I can't install flash on ubuntu 14.04 to play facebook games, videos or youtube videos [duplicate]

I can't install flash on Ubuntu 14.04 to play facebook games, videos or youtube videos.

I'm using firefox.
I've installed Ubuntu restricted extras.

Solution 1:

An alternative would be trying Google Chrome, which has flash built in. If you also need to install java support to your browsers, I recommend using the iced tea plugin here

How to manually install Adobe's Flash NPAPI plugin for browsers such as Firefox, Iceweasel and SeaMonkey

Access https://get.adobe.com/flashplayer/otherversions/
Select your architecture: Linux (32-bit) or Linux (64-bit).
- If you're unsure about your system's architecture, run the shell command uname -i: if it returns something having the number 64 in it, your system is 64-bit. Otherwise, it's 32-bit.
Download the NPAPI tarball: select the option having (.tar.gz) - NPAPI in it and then click onto the "Download now" button.
- A tarball is a file with a ".tar.xxx" extension, where "xxx" is an extension for compressed files, like e.g. zip, gz, bz2, 7z etc. Hence, tarball.tar.gz, tarball.tar.zip, tarball.tar.7z and tarball.tar.bz2 are all examples of tarballs.
Save the tarball into the /tmp folder with the name flash.tar.gz. If your browser automatically downloads the tarball, thus making it impossible for you to rename the tarball before the download starts, wait for the download to end, then go to the folder where the tarball's been put, rename the tarball to flash.tar.gz and then move it to /tmp.
Start the shell terminal and then run this command:
```
cd /tmp ; tar -xvf flash.tar.gz
```

Now run this supercommand in order to place the Adobe Flash plugin in the system folder:

if ! [ -d /usr/lib/adobe-flashplugin/ ]; then sudo mkdir /usr/lib/adobe-flashplugin ; else echo /usr/lib/adobe-flashplugin/ already exists ; fi ; sudo cp -f libflashplayer.so /usr/lib/adobe-flashplugin/ ; sudo ln -sf /usr/lib/adobe-flashplugin/libflashplayer.so /usr/lib/flashplugin-installer/libflashplayer.so

Then run this command in order to place the Adobe Flash folders in their respective locations:
```
sudo cp -rf /tmp/usr /
```
You can now run your Mozilla/Gecko browser (Firefox, Iceweasel or SeaMonkey) and then access the URL about:plugins in order to check if your browser has detected the flash plugin located at /usr/lib/adobe-flashplugin/libflashplayer.so (it should be also visible by accessing about:addons and then the Plugins section). If you see something like Shockwave Flash 24.0 r0, then go to http://www.adobe.com/software/flash/about in order to check if the flash applet detects your NPAPI flash install and tells you which version you're currently using.
- It's possible that your browser will show the plugin location as being /usr/lib/flashplugin-installer/libflashplayer.so instead of /usr/lib/adobe-flashplugin/libflashplayer.so. If it happens, ignore it: it's normal.
Restart your computer just to make sure that the applications menu shows your brand-new "Adobe Flash Player" control panel. If it doesn't, you should be able to start it by running this shell command:
```
/usr/bin/flash-player-properties
```

Note: if you're using the 32-bit SeaMonkey on a 64-bit system, the browser won't "see" the plugin. Use another browser (e.g. Firefox).

How to manually uninstall Adobe's Flash NPAPI plugin for browsers such as Firefox, Iceweasel and SeaMonkey

Open a shell terminal window and run this supercommand:

sudo rm -r /usr/lib/adobe-flashplugin /usr/lib/flashplugin-installer/libflashplayer.so /usr/bin/flash-player-properties /usr/lib/kde4/kcm_adobe_flash_player.so /usr/lib64/kde4/kcm_adobe_flash_player.so /usr/share/applications/flash-player-properties.desktop /usr/share/kde4/services/kcm_adobe_flash_player.desktop /usr/share/pixmaps/flash-player-properties.png ; cd /usr/share/icons/hicolor ; sudo find . -name "flash-player-properties.png" -delete

How to manually install Adobe's Flash PPAPI plugin for a WebKit browser such as Opera

Access https://get.adobe.com/flashplayer/otherversions/
Select your architecture: Linux (32-bit) or Linux (64-bit).
- If you're unsure about your system's architecture, run the shell command uname -i: if it returns something having the number 64 in it, your system is 64-bit. Otherwise, it's 32-bit.
Download the PPAPI tarball: select the option having (.tar.gz) - PPAPI in it, and then hit the "Download now" button.
- A tarball is a file with a ".tar.xxx" extension, where "xxx" is an extension for compressed files, like e.g. zip, gz, bz2, 7z etc. Hence, tarball.tar.gz, tarball.tar.zip, tarball.tar.7z and tarball.tar.bz2 are all examples of tarballs.
Save the tarball into the /tmp folder with the name pepflash.tar.gz. If your browser automatically downloads the tarball, thus making it impossible for you to rename the tarball before the download starts, wait for the download to end, then go to the folder where the tarball's been put, rename the tarball to pepflash.tar.gz and then move it to /tmp.
Start the shell terminal and then run this command:
```
cd /tmp ; tar -xvf pepflash.tar.gz
```

Now run these commands in order to place the Adobe Flash plugin in the system folder:

if ! [ -d /usr/lib/adobe-flashplugin/ ]; then sudo mkdir /usr/lib/adobe-flashplugin ; else echo /usr/lib/adobe-flashplugin/ already exists ; fi ; sudo cp -f libpepflashplayer.so /usr/lib/adobe-flashplugin/ ; sudo ln -sf /usr/lib/adobe-flashplugin/libpepflashplayer.so /usr/lib/flashplugin-installer/libpepflashplayer.so

You can now run your WebKit / Opera browser, then access the URL about:plugins in order to check if your browser has detected the flash plugin located at /usr/lib/adobe-flashplugin/libpepflashplayer.so. Don't forget to click the Show details button (upper right) in order to expand the information fields and show extra info about each detected plugin. If you see something like Adobe Flash Player located at /usr/lib/adobe-flashplugin/libpepflashplayer.so, then go to http://www.adobe.com/software/flash/about just to make sure that the flash applet detects your PPAPI flash install and tells you which version you're currently using.

How to manually install Adobe's Flash PPAPI plugin for Google Chrome and Google Chromium browsers

If you're using Google Chrome/Chromium, it already comes with its own bundled PPAPI Flash plugin located at ~/.config/google-chrome/PepperFlash/some_version_number/libpepflashplayer.so. However, if videos aren't working with Google Chrome/Chromium when you're on Facebook, YouTube et cetera (you hear the audio, but doesn't see any video), then you're probably trying to watch HTML5 videos but your GPU (Graphics Processing Unit) has a built-in rendering blacklist that's avoiding video acceleration required by HTML5.

In order to fix this issue, start Google Chrome/Chromium, access this URL:

chrome://flags/#ignore-gpu-blacklist

...then activate the above option and restart Google Chrome/Chromium.

If the above solution doesn't solve the issue, follow the 6 steps provided at How to manually install Adobe's Flash PPAPI plugin for a WebKit browser such as Opera, then back up Google's PepperFlash plugin and create a symbolic link to Adobe's flash PPAPI plugin.

If e.g. your Chrome/Chromium browser is using PepperFlash plugin version 24.0.0.186 and you downloaded Adobe's flash PPAPI plugin version 24.0.0.186 (same version of Google's PepperFlash), then this is the shell command you'll have to issue after you install Adobe's Flash PPAPI plugin:

mv ~/.config/google-chrome/PepperFlash/24.0.0.186/libpepflashplayer.so ~/.config/google-chrome/PepperFlash/24.0.0.186/libpepflashplayer.so.bak ; sudo ln -sf /usr/lib/adobe-flashplugin/libpepflashplayer.so ~/.config/google-chrome/libpepflashplayer.so
