Lots of issues with Mozilla
Mozilla lags a lot when it's started, it takes ten thousand hours to open a tab when it's started. YouTube lags a lot and specially when 60fps videos are watched and shorts are being watched. Otherwise everything works well with other browsers, but Mozilla.
Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.
You will need to restart Firefox for this to take effect so save all work first (e.g., mail you are composing, online documents you're editing, etc.,) and then perform these steps:
- Click the menu button and select Options (Windows) or Preferences (Mac, Linux).
- Select the General panel.
- Under Performance, uncheck Use recommended performance settings. Additional settings will be displayed.
- Uncheck Use hardware acceleration when available.
- Close Firefox completely and then restart Firefox to see if the problem persists.
