I am trying different add-ons from your suggestions hoe ever nothing is working. Youtube videos are not playing same as videos and audios from different other sites

Chosen solution

Did you disable those add-ons?

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.
    Fx55Performance-disableHWA
  4. Uncheck Use hardware acceleration when available.
  5. Close Firefox completely and then restart Firefox to see if the problem persists.

Did this fix your problems? Please report back to us!

If the problem is resolved, you should check for updates for your graphics driver by following the steps mentioned in these Knowledge base articles:

Thank you.

You have several YouTube add-ons. Disable them.


Make sure you are not blocking content.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

In that case : would you please remove the Chosen Solution mark  ?

You can do so by clicking on the 'Undo' button to the right of that post.

When you say :

" Youtube videos are not playing same as videos and audios from different other sites "

Could you be a bit more specific - like : what exactly is the difference  ?

Chosen Solution

Did you disable those add-ons?

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.
    Fx55Performance-disableHWA
  4. Uncheck Use hardware acceleration when available.
  5. Close Firefox completely and then restart Firefox to see if the problem persists.
