I'm running Firefox 99.0.1 on Ubuntu 22.04. Recently (I think since I updated to Ubuntu 22.04 about a week ago), Firefox has been refusing to show me file upload dialogs. When I click a button that's supposed to give me one, nothing happens.
This has been happening with: - The "attach files" button in Gmail - A file upload button on Gradescope (website for managing homework assignments) - File -> Open File... and Ctrl+O.
Dragging and dropping a file onto an email in Gmail does attach the file -- it's just that the button doesn't work.
I've tried restarting, and I've tried running Firefox in Troubleshoot Mode -- so far nothing has fixed the problem. What else should I do?
