Another thing to try : Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

You will need to restart Firefox for this to take effect so save all work first (e.g., mail you are composing, online documents you're editing, etc.,) and then perform these steps:

In Firefox 54 and below:

  1. Click the menu button New Fx Menu and select Options (Windows) or Preferences (Mac, Linux).
  2. Select the Advanced panel and the General tab.
  3. Uncheck Use hardware acceleration when available.
  4. Close Firefox completely and then restart Firefox to see if the problem persists.

In Firefox 55 and above:

  1. Click the menu button New Fx Menu and select Options (Windows) or Preferences (Mac, Linux).
  2. Select the General panel.
  3. Under Performance, uncheck Use recommended performance settings. Additional settings will be displayed.

  4. Uncheck Use hardware acceleration when available.
  5. Close Firefox completely and then restart Firefox to see if the problem persists.

While removing your firefox, won't delete your profile. try with new profile.


Create a new profile as a test to check if your current profile is causing the problems.

See Creating a profile:

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem

In case you have Adobe Flash installed on your system, would you please go to Options => Add-ons => Plugins and make sure that Shockwave Flash is set to 'Ask to Activate'  ?

I was under the impression that you couldn't play videos on other sites
either (?) You shouldn't have to install 'HTML5 Video Everywhere' for YouTube, as YouTube uses HTML5 by default these days.
