Firefox 45.9.0 can no longer play Youtube movies ?
« on: September 20, 2019, 08:09:16 am »
I can no longer get Firefox 45.9.0 to play Youtube movies. It used to work in the past but I cannot remember when that would no longer work.
Is this a known problem ? And is there a solution ?

Hi Lars

I have just checked  - it works here as usually.

Maybe I screwed something up about the configuration ("about:config"). Is there a way to reset the configuration to some "safe default" or do I need to create a new profile ?

You could try setting parameters: / safe-mode
Or refresh it
But the one that suits me best is the Seamonkey version 2.42.9 esr

You can start with --safe-mode or go to about:support which gives a couple of options. The nuclear one is refresh which will reset your profile. There's other possible relevant info on that page.
Make sure you have the FFmpeg libs installed as well.

1) I did have FFMPEG installed
2) I now did a "Refresh Firefox" and that has fixed the problem.

Many thanks for your help !
