I'm having issues with Ubuntu now. It had been a smooth ride since the start over a year ago, but I've started using my spare laptop with Ubuntu 24 on it and Firefox keeps acting up. Occasionally, it won't take text inputs at all, preventing me from typing anything. I eventually figured out that restarting the browser fixes the issue, but I didn't have this before. I'm not seeing errors at startup, I have my computer set to be "verbose" during boot.
No weird mods to the OS, just straight forward apt/snap/flatpack installs for everything. I haven't tinkered with any system parameters or settings in a long time.

I'm guessing an update borked something, is it fixable?
