Hi megapro17,

If you are willing, please try to reproduce the issue entering safe mode as here: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

If it is still reproducing, can you please give me some more details about the version of Firefox on which you reproduced this issue, and what add-ons you have installed on it? I tried on some versions of Firefox and didn't managed to reproduce.

I tried with safe mode, no difference. 
None of add-ons was installed.
Just try to watch any video at 2x speed firstly in chrome, then in firefox. You must clearly hear the difference. In chrome speech is clearly understandable, in firefox some distorsions appear. 

Here is video example. I can hear heavy distorsions on 1:07, 1:42 https://www.youtube.com/watch?v=VJ-syLh4JV0

What version of Firefox do you use?

Try also with a new profile. You can find the steps here: https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles

I tried a new profile and etc, it is not a problem in settings, it in the program.
