Today is 11-12-2025. After the last update a few days ago, many of my websites would not load up on firefox and when try on Edge or Chrome, they would work perfectly. I did a recovery back to 10-31-2025 and everything worked fine. Now I am afraid to do another update until I know what is going on. What would you suggest? Thanks,

Fullscreen Error with Multiple Displays when Hardware Acceleration is disabled

I have my desktop extended across two displays. If I disable Hardware Acceleration in Firefox, entering fullscreen causes the window to be slightly offset down and right, leaving a thin band on the top and left sides of the screen where the desktop background and taskbar are visible behind the Firefox window.

From testing I have determined that this issue does not occur if I only have one monitor enabled or the monitors are mirroring the same display. I have also determined that the issue only occurs when Hardware Acceleration is disabled.

Firefox may still be downloading the latest update in the background even if the “About Firefox” window says it’s up to date. Updates are applied after restarting Firefox
