I'm using the Mozilla-provided install of Firefox instead of Ubuntu's, because of an issue with KeepassXC and snap.
When I went into the Web Browser setting, I somehow clicked on Chromium, which is the only entry in the drop down. Now I can't get rid of it, so web links now bring up Chromium, which isn't what I want.
I would be happy just to get it cleared out, but even happier if I could replace it with my custom Firefox.
If I need to go to a config file to fix manually, that would be fine too.
Thanks.
