Есть два типа плагинов для браузеров, в зависимости от API, на котором они основаны:

- Netscape plugin API (NPAPI): эти плагины работают в Firefox, Opera и большинстве других браузеров (не в Chromium).
- Pepper plugin API (PPAPI): эти плагины работают только в Chromium и Chrome.

Most plugins on this page are NPAPI-only, unless noted otherwise.

## Flash Player

### Shumway

Shumway is an HTML5 technology experiment that explores building a faithful and efficient renderer for the SWF file format without native code assistance. As of 2013-01-01, the plugin may be installed directly from Mozilla's github.io site. According to the Shumway wiki, "Integration with Firefox is a possibility if the experiment proves successful."

Shumway is also embedded in Firefox Nightly/Aurora builds.

### Gnash

See also Wikipedia:Gnash.

GNU Gnash is a free (libre) alternative to Adobe Flash Player. It is available both as a standalone player for desktop computers and embedded devices, as well as a browser plugin, and supports the SWF format up to version 7 (with versions 8 and 9 under development) and about 80% of ActionScript 2.0.

There are multiple packages available: gnashAUR[ссылка недействительна: сохранено в aur-mirror], gnash-kde4AUR[ссылка недействительна: сохранено в aur-mirror], gnash-gitAUR.

Note: If you find that Gnash does not work properly right out of the box, then you may also need to install gstreamer0.10-ffmpegAUR from the official repositories.

### Lightspark

Lightspark is another attempt to provide a free alternative to Adobe Flash aimed at supporting newer Flash formats. Lightspark has the ability to fall back on Gnash for old content, which enables users to install both and enjoy wider coverage. Although it is still very much in development, it supports some popular sites.

Lightspark can be установлен with the package lightsparkAUR[ссылка недействительна: сохранено в aur-mirror] or lightspark-gitAUR.

### Adobe Flash Player

#### Установка

Пакет, который нужно установить зависит от браузера, которым вы пользуетесь.

- Версию NPAPI можно установить с помощью пакета flashplugin из официальных репозиториев. Этот плагин больше не поддерживается Adobe и остановился на версии 11.2; однако Adobe будет предоставлять обносления безопасности в течение 5 лет (т.е. до 2017).

- Версия PPAPI распространяется вместе с Google Chrome. Если вы используете Chromium или какой-либо другой браузер, использующий интерфейс PPAPI, то смотрите Chromium#Flash Player plugin для дополнительной информации.

Примечание: Некоторым Flash приложениям требуется ttf-ms-fontsAUR из AUR для того, чтобы правильно отображать текст.

#### Configuration

To change the preferences (privacy settings, resource usage, etc.) of Flash Player, right click on any embedded Flash content and choose Settings from the menu, or go to the Adobe website. There, a Flash animation will give you access to your local settings.

You can also use the Flash settings file `/etc/adobe/mms.cfg`.

Warning: Flash hardware acceleration could be still unstable. See [1]

To enable VDPAU, uncomment the following line:

    EnableLinuxHWVideoDecode=1

A more detailed example configuration:

    /etc/adobe/mms.cfg

    AVHardwareDisable = 0
    FullScreenDisable = 0
    LocalFileReadDisable = 1
    FileDownloadDisable = 1
    FileUploadDisable = 1
    LocalStorageLimit = 1
    ThirdPartyStorage = 1
    AssetCacheSize = 10
    AutoUpdateDisable = 1
    LegacyDomainMatching = 0
    LocalFileLegacyAction = 0
    AllowUserLocalTrust = 0
    # DisableSockets = 1
    OverrideGPUValidation = 1
    DisableDeviceFontEnumeration = 1 #Prevent sites to identify you by snooping the installed fonts

You can also refer to the mms.cfg from Gentoo, which is extensively commented.

#### Disable the "Press ESC to exit full screen mode" message

Note: This only works for the NPAPI plugin.

For a way to disable this message see this ubuntuforums.org post.

Backup `libflashplayer.so`:

    # cp /usr/lib/mozilla/plugins/libflashplayer.so /usr/lib/mozilla/plugins/libflashplayer.so.backup

Make a copy of it in your home directory:

    # cp /usr/lib/mozilla/plugins/libflashplayer.so ~/

Install wine from the official repositories.

Download `Flash Fullscreen Patcher.zip` from this page, extract and execute with `wine`:

    $ wget https://www.dropbox.com/s/ssrlsnx1csdyc8p/Flash%20Fullscreen%20Patcher%20v3.00%20%2B%20Source.zip
    $ unzip Flash\ Fullscreen\ Patcher\ v3.00\ +\ Source.zip Flash\ Fullscreen\ Patcher.exe
    $ wine Flash\ Fullscreen\ Patcher.exe

Patch `libflashplayer.so` (the one from your home directory) using the GUI. Copy the patched Flash Player back to the plugins directory:

    # cp ~/libflashplayer.so /usr/lib/mozilla/plugins/

#### Multiple monitor full-screen fix

Note:

- This only works for the NPAPI plugin.
- There is also a package flashplugin-focusfixAUR in the AUR that includes this fix.

  sourced from this post on webupd8

When using a multiple monitor setup, or swapping between virtual desktops, it is possible to lose focus on a fullscreen flash window. In such a case, the adobe flash-plugin will automatically exit full-screen mode. This may not be to your liking.

Unfortunately, this behavior is hard coded into the binary. In order to change this behavior it is necessary to alter the binary.

First you will need a hex editor, such as ghex.

Then, you will need to alter the adobe flash-plugin binary, which is commonly located at `/lib/mozilla/plugins/libflashplayer.so`. It is prudent of course to first backup the file, in case you want to revert the behavior or make a mistake while editing.

    # cp /usr/lib/mozilla/plugins/libflashplayer.so /usr/lib/mozilla/plugins/libflashplayer.so.backup

Then open the binary in the hex editor with root privileges:

    # ghex /usr/lib/mozilla/plugins/libflashplayer.so

Using the hex editor find the string `_NET_ACTIVE_WINDOW`. In ghex the readable string is on the right hand side of the window, and the hex is on the left, you are trying to locate the readable string. It should be easy to find using a search function.

Upon finding `_NET_ACTIVE_WINDOW` rewrite the line, but do not change the length of the line, for example `_NET_ACTIVE_WINDOW` becomes `_XET_ACTIVE_WINDOW`.

Save the binary, and restart any processes using the plugin (as this will crash any instance of the plugin in use.)

#### Fullscreen fix for GNOME 3

If you have problems with Flash's fullscreen-mode (video freezes but audio keeps playing), then it is probably because the fullscreen flash window is displayed behind the browser window. This is a known upstream bug in mutter. You can easily fix this by using devilspie:

Install devilspie from the official repositories.

Create the `~/.devilspie` directory:

    # mkdir ~/.devilspie

Now you have to create a config file for each browser you use (see below)

Finally, add devilspie to your list of startup items by adding the following file to `~/.config/autostart`

    ~/.config/autostart/devilspie.desktop

    [Desktop Entry]
    Name=devilspie
    Exec=devilspie
    Hidden=false
    NoDisplay=false
    X-GNOME-Autostart-enabled=true

##### Firefox

    ~/.devilspie/flash-fullscreen-firefox.ds

    (if
    (is (application_name) "plugin-container")
    (begin
    (focus)
    )
    )

##### Chrome / Chromium

    ~/.devilspie/flash-fullscreen-chrome.ds

    (if
    (is (application_name) "exe")
    (begin
    (focus)
    )
    )

##### Epiphany / GNOME Web

    ~/.devilspie/flash-fullscreen-epiphany.ds

    (if
    (is (application_name) "WebKitPluginProcess")
    (begin
    (focus)
    )
    )

### Video players workarounds

#### Open-with Firefox extension

1. Install Open-with add-on.
2. Open `about:openwith`, select Add...
3. In the dialog select a video streaming capable player (e.g. /usr/bin/mpv).
4. (Optional step) Add needed arguments to the player (e.g. you may want `--force-window --ytdl` for mpv)
5. (Optional step) Choose how to display the dialogs using the left panel.
6. Right click on links or visit pages containing videos. If the site is supported, the player will open as expected.

The same procedure can be used to associate video downloaders such as youtube-dl.

## PDF viewer

### PDF.js

PDF.js is a PDF renderer created by Mozilla and built using HTML5 technologies.

For Firefox it is available as a plugin, which is included in Firefox since version 19.

For Chromium and Google Chrome there is an experimental extension in the Chrome web store or alternatively it can be built from the source of Pdf.js.

### External PDF viewers

To use an external PDF viewer you need #MozPlugger or #kpartsplugin.

If you want to use MozPlugger with Evince, for example, you have to find the lines containing `pdf` in the `/etc/mozpluggerrc` file and modify the corresponding line after `GV()` as below:

    repeat noisy swallow(evince) fill: evince "$file"

(replace `evince` with something else if it is not your viewer of choice).

If this is not enough, you may need to change 2 values in `about:config`:

- Change `pdfjs.disabled`'s value to true;
- Change `plugin.disable_full_page_plugin_for_types`'s value to an empty value.

Restart and it should work like a charm!

### Adobe Reader

Due to licensing restrictions, Adobe Reader cannot be distributed from any of the official Arch Linux repositories. There are versions available in the AUR. Please note that no matter how many votes it receives, Adobe Reader will never be included in the official repositories.

Also, there are localizations available in many languages.

#### 32-bit

Adobe Acrobat Reader is only available as a 32-bit binary. It can be installed with the acroreadAUR package, available in the AUR.

This package installs the Acrobat Reader application as well as the Firefox plugin. Note that hardware-assisted rendering is unavailable under Linux (at least using a Geforce 8600GTS with driver version 185.18.14).

#### 64-bit

There is yet to be an official 64-bit version of Adobe Reader.

To use it in a 64-bit environment, you can:

- Follow this guide originally posted in the forums. It involves creating a chrooted environment that could be reused for other 32-bit only applications.

- Install acroreadAUR (with all its 32-bit dependencies) from AUR. Be advised that the Firefox plugin cannot be used directly with this binary -- it will not load in the 64-bit browser. To load it install the nspluginwrapper package from the official [multilib] repository and run:

    $ nspluginwrapper -v -a -i

as a normal user. This checks the plugin directory and links the plugins as needed.

## Citrix

See Citrix.

## Java (IcedTea)

Note: Java does not work on Chromium, since they've disabled all NPAPI pluggins. Install another browser to use any Java plugin.

To enable Java support in your browser, you have two options: the open-source OpenJDK (recommended) or Oracle's proprietary version. For details about why OpenJDK is recommended see this.

To use OpenJDK, you have to install the IcedTea browser plugin, icedtea-web.

If you want to use Oracle's JRE, install the jreAUR (or jre6AUR) package, available in the AUR.

See Java#OpenJDK for additional details and references.

Note: If you experience any problems with the Java plugin (e.g. it is not recognized by the browser), you can try this solution[broken link: invalid section].

## Pipelight

See Pipelight.

## Multimedia playback

Many browsers support the GStreamer framework to play multimedia inside HTML5 `<audio>` and `<video>` elements. Check the optional dependencies of the browser package (or webkitgtkAUR/webkitgtk2AUR if using a webkit-based browser) to see which version of GStreamer is supported: this can be either `gst-*` for the current version, or `gstreamer0.10-*` for the legacy version. See GStreamer#Installation for the description of each plugin.

## Other

### MozPlugger

MozPlugger can be installed with the mozpluggerAUR package.

MozPlugger is a Mozilla plugin which can show many types of multimedia inside your browser. To accomplish this, it uses external programs such as MPlayer, xine, Evince, OpenOffice, TiMidity, etc. To modify or add applications to be used by MozPlugger just modify the `/etc/mozpluggerrc` file.

For example, MozPlugger uses OpenOffice by default to open `doc` files. To change it to use LibreOffice instead, look for the OpenOffice section:

    /etc/mozpluggerrc

    ...
    ### OpenOffice
    define([OO],[swallow(VCLSalFrame) fill: ooffice2.0 -nologo -norestore -view $1 "$file"
        swallow(VCLSalFrame) fill: ooffice -nologo -norestore -view $1 "$file"
        swallow(VCLSalFrame) fill: soffice -nologo $1 "$file"])
    ...

and add LibreOffice at the beginning of the list:

    /etc/mozpluggerrc

    ...
    ### LibreOffice/OpenOffice
    define([OO],[swallow(VCLSalFrame) fill: libreoffice --nologo --norestore --view $1 "$file"
        swallow(VCLSalFrame) fill: ooffice2.0 -nologo -norestore -view $1 "$file"
        swallow(VCLSalFrame) fill: ooffice -nologo -norestore -view $1 "$file"
        swallow(VCLSalFrame) fill: soffice -nologo $1 "$file"])
    ...

Note: Be sure to also choose LibreOffice as your preferred application to open `doc` files.

As another simple example, if you want to open `cpp` files with your favorite text editor (we will use Kate) to get syntax highlighting, just add a new section to your `mozpluggerrc` file:

    /etc/mozpluggerrc

    text/x-c++:cpp:C++ Source File
    text/x-c++:hpp:C++ Header File
        repeat noisy swallow(kate) fill: kate -b "$file"

To change the default of MPlayer so that mpv is used instead, change the appropriate lines such that:

    /etc/mozpluggerrc

    ...
    ### MPlayer

    #define(MP_CMD,[mplayer -really-quiet -nojoystick -nofs -zoom -vo xv,x11 -ao esd,alsa,oss,arts,null -osdlevel 0 $1 </dev/null])
    define(MP_CMD,[mpv -really-quiet $1 </dev/null])

    #define(MP_EMBED,[embed noisy ignore_errors: MP_CMD(-xy $width -wid $window $1)])
    define(MP_EMBED,[embed noisy ignore_errors: MP_CMD(--autofit=$width -wid $window $1)])

    #define(MP_NOEMBED,[noembed noisy ignore_errors maxaspect swallow(MPlayer): MP_CMD($1)])
    define(MP_NOEMBED,[noembed noisy ignore_errors maxaspect swallow(mpv): MP_CMD($1)])

    ...

    #define(MP_AUDIO,[mplayer -quiet -nojoystick $1 </dev/null])
    define(MP_AUDIO,[mpv -really-quiet $1 </dev/null])

    #define(MP_AUDIO_STREAM,[controls stream noisy ignore_errors: mplayer -quiet -nojoystick $1 "$file" </dev/null])
    define(MP_AUDIO_STREAM,[controls stream noisy ignore_errors: mpv -really-quiet $1 "$file" </dev/null])
    ...

For a more complete list of MozPlugger options see this page.

### kpartsplugin

The KParts plugin is a plugin that uses KDE's KPart technology to embed different file viewers in the browser, such as Okular (for PDF), Ark (for different archives), Calligra Words (for ODF), etc. It cannot use applications that are not based on the KPart technology.

The KParts plugin can be installed with the package kpartsplugin[ссылка недействительна: сохранено в aur-mirror], available in the official repositories.

## Troubleshooting

### Flash Player: no sound

Flash Player outputs its sound only through the default ALSA device, which is number 0. If you have multiple sound devices (a very common example is having a sound card and HDMI output in the video card), then your preferred device may have a different number.

For a list of available devices with their respective numbers, run:

    $ aplay -l

     **** List of PLAYBACK Hardware Devices ****
     card 0: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
       Subdevices: 1/1
       Subdevice #0: subdevice #0
     card 1: DX [Xonar DX], device 0: Multichannel [Multichannel]
       Subdevices: 0/1
       Subdevice #0: subdevice #0
     card 1: DX [Xonar DX], device 1: Digital [Digital]
       Subdevices: 1/1
       Subdevice #0: subdevice #0

In this case, the HDMI output is `card 0` and the sound card is `card 1`. To make your sound card the default for ALSA, create the file `.asoundrc` in your home directory, with the following content:

    ~/.asoundrc

    pcm.!default {
        type hw
        card 1
    }

    ctl.!default {
        type hw
        card 1
    }

### Flash Player: blocking sound for other applications or delayed playback

If sound is delayed within Flash videos or Flash stops sound from any other application, then make sure you do not have `snd_pcm_oss` module loaded:

    $ lsmod | grep snd_pcm_oss

You can unload it:

    # rmmod snd_pcm_oss

and restart the browser to see if it helps.

### Flash Player: performance

Adobe's Flash plugin has some serious performance issues, especially when CPU frequency scaling is used. There seems to be a policy not to use the whole CPU workload, so the frequency scaling governor does not clock the CPU any higher. To work around this issue, see CPU frequency scaling#Switching threshold

### Flash Player: low webcam resolution

If your webcam has low resolution in Flash (the image looks very pixelated) you can try starting your browser with this:

    $ LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so [broswer]

### Flash Player: black bars in full screen playback on multi-headed setups

The Flash plugin has a known bug where the full screen mode does not really work when you have a multi-monitor setup. Apparently, it incorrectly determines the full screen resolution, so the full screen Flash Player fills the correct monitor but gets scaled as if the monitor had the resolution of the total display area.

To fix this, you can use the "hack" described here. Simply download the source from the link given on the page, and follow the instructions in the README.

Совет: The hack is available in the AUR and can be installed with the fullscreenhackAUR[ссылка недействительна: сохранено в aur-mirror] package
Примечание: While the author mentions using NVDIA's TwinView, the hack should work for any multi-monitor setup

### Flash Player: blue tint on videos with NVIDIA

An issue with flashplugin versions 11.2.202.228-1 and 11.2.202.233-1 causes it to send the U/V panes in the incorrect order resulting in a blue tint on certain videos. Version 0.5 of libvdpau includes a workaround to fix this, see the official announcement.

### Flash Player: leaking overlay with NVIDIA

This bug is due to the incorrect color key being used by the flashplugin version 11.2.202.228-1 (see this post on the NVIDIA forums) and causes the Flash content to "leak" into other pages or solid black backgrounds. To avoid this issue simply export `VDPAU_NVIDIA_NO_OVERLAY=1` within either your shell profile (e.g. `~/.bash_profile` or `~/.zprofile`) or `~/.xinitrc`

### Flash Player: videos not working on older systems

If you have Adobe Flash installed on an older system and you start playing a video which simply turns black with nothing happening, it is most likely that your CPU does not support SSE2. You can simply check this by looking at your CPU flags with this command:

    $ grep sse2 /proc/cpuinfo

If no results are returned, then you need to install an older version of Flash (for example 10.3, or 11.1). Older versions possibly will have vulnerabilities. You should then consider sandboxing Firefox using sandfoxAUR. See the sandfox homepage for usage information.

Older versions of Flash are available here: https://www.adobe.com/products/flashplayer/distribution3.html You need to copy `libflashplayer.so` to the folder `/usr/lib/mozilla/plugins/`

Older flashplugin packages can be downloaded from the AUR e.g. flashplugin-10AUR[ссылка недействительна: сохранено в aur-mirror].

The most recent package without SSE2 is `flashplugin-11.1.102.63-1-i686.pkg.tar.xz`. If you use the packaged version, you have to add `IgnorePkg = flashplugin` to `/etc/pacman.conf`.

### Plugins are installed but not working

A common problem is that the plugin path is unset. This typically occurs on a new install, when the user has not re-logged in before running Firefox after the installation. Test if the path is unset:

    echo $MOZ_PLUGIN_PATH

If unset, then either re-login, or source `/etc/profile.d/mozilla-common.sh` and start Firefox from the same shell:

    source /etc/profile.d/mozilla-common.sh && firefox

### Gecko Media Player will not play Apple trailers

If Apple Trailers appear to start to play and then fail, try setting the user agent for your browser to:

    QuickTime/7.6.2 (qtver=7.6.2;os=Windows NT 5.1Service Pack 3)
