Whenever I open a lesson on duolingo, rectangles start to appear, flickering on the screen. It's completely fine on troubleshoot mode, but when i disable all my extentions on normal mode (i still had account containers on), it still happens.

You can try to disable hardware acceleration in Firefox.

Close and restart Firefox after modifying the setting to make changes effective.

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