It's my fast day in Firefox browser but I am little bit unsatisfied as sometime a small black screen pop up by which I cannot interact with the product properly. I have share one screenshot of a YouTube video, you can clearly see that two small black box is there in the video. You may check the video here- https://www.youtube.com/watch?v=T9A_KkNyxh8. I really become very angry when it happen, for that I cannot even sign in into my google account properly.

Is this with all websites/pages, some, a few?

Start Firefox using Troubleshoot(Safe) Mode {web link}

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

Nope, nothing happen, still the problem is there. For now I know it is happening in YouTube and while signing in in my google account.

Do this for Google and YouTube.


Delete browsing, search and download history on Firefox {web link}

Remove a single website from your history {web link}

Open the History Manager <Control> (Mac=<Command>) <Shift> H. In the search bar, enter the name of the site. Right-click on one of the listings and select Forget About This Site. This should remove all information, including any site settings And Passwords.

Could this possibly be Closed Captions (CC button) or an ad that is blocked someway ?

Did you close and restart Firefox after disabling hardware acceleration in Firefox as that is mandatory ?

what do you mean disabling hardware acceleration in Firefox ???????

Start Firefox in Safe Mode {web link} While you are in safe mode;

Disable Hardware Acceleration {web link}

Restart Firefox. Are there any problems?
