Hi team in general the browser works fine and firefox is my first choice, I haven't any error or crush. My problem is about the video player, in particolar looking video on Youtube. When the video are running in the middle of the screen some lines appear for few seconds, lines are looking an horizontal flash. The video continue to run and the audio too just only the images are disturbing by this lines.

I tried to reinstall Firefox but problem persist.

Thanks

Fabio

Chosen solution

You can try to disable hardware acceleration in Firefox.

  • Options/Preferences -> Advanced -> General -> Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.
