Firefox hangs and stops loading any pages after random period of time

more options

I'm not sure what is causing this, but it started at least a few months ago. I will be using firefox, and anywhere between a few minutes, or a few days, it will suddenly stop loading anything and I will have to completely quit it and restart it to get anything working again. No, it is not the HTTP3 problem; that was the first thing I tried. I've also uninstalled, and reinstalled the entire program, clearing all settings, etc. I am on windows. Generally good on firefox updates, will check and update usually every week or two.

Funny thing is, I also installed firefox nightly and that does not have this problem (although I have not used it as extensively as I normally do when browsing, so maybe I didn't hit whatever triggers this issue). It also works properly on other computers (as far as I'm aware). So I still think something is corrupt or wrong with my normal firefox program. I just don't know what or how.

Does Firefox still has internet access if you check this in the Network Monitor or via the DNS Lookup tool on the about:networking page ?

I will give this a try next time it happens, thanks!

Ok so I think I figured out when it happens. It's only when my VPN (ProtonVPN) disconnects or reconnects, then firefox seems to not know how to handle the new connection? And so it just doesn't load anything at all. Is there anything I can do about that?

Helpful?
