hello,

Start Firefox in Troubleshoot Firefox issues using Safe Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).

Don't make any changes on the Safe mode start window.

Try to disable hardware acceleration.

Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

I hope resolve your problem then reply back to me.

Thank you for asked Question in Mozilla Support.

Hello,

Precisely! Turning hardware acceleration off will fix this problem. Thanks!
