Firefox clipboard stops working after a while
Hello, My Windows desktop Firefox browser's clipboard randomly stops working usually about 30-60 minutes in from its launch. Restarting the browser doesn't help. Only fix is to restart the whole computer. It's not a system-wide clipboard failure since when the issue occurs, the clipboard continues to work in other utilities and browsers (tested in Chrome). I can copy something from elsewhere and paste to Firefox. But, can't copy from Firefox and paste somewhere inside or outside of Firefox. Hence, surely the issue's isolated to the browser.
If it helps, I'm currently using Firefox 92.0.1 (64-bit) on a Windows 10 Pro computer (HP EliteBook 850 G7) running Windows 10.0.19042 Build 19042. Please refer the attached screenshots for my currently enabled add-ons.
