Flash not working in Firefox

I have installed Ubuntu 11.10 in my system with gnome shell.

When I try to watch any videos on any video streaming website in Firefox, I am not able to watch. At the same time those videos can be played in Chromium browser.

I have already installed Flash 11 and the Flash plugin for Firefox as well.

Solution 1:

I had a similar issue before. Try to remove flash first by running the following command in a terminal:

 sudo apt-get purge adobe-flashplugin

Then try to reinstall flash with this command:

sudo apt-get install flashplugin-nonfree

That worked for me.

Solution 2:

Try to install the Firefox Add-On Flash-Aid, that Add-On will configure Flash for your system. You can easily choose between stable and beta version.

Solution 3:

I had a similar problem. This is how I was able to resolve it.

1. Go to the Firefox add-ons screen, ► Tools ► Add-ons ► Search for flash-aid then install it.
2. Restart Firefox.
3. In Firefox go to ► Tools ► Flashaid ► Quick Mode - Install beta flash
4. Restart the browser.
