'''During the last week or so I have encountered the issue that one or more of my Firefox profiles keep resetting after every update.''' I noticed there's couple of threads with similar issues already but the generic profile restore instructions are not helping at all since it seems that Firefox is actually wiping the default profile on every update. I'm running Firefox 150.0.1 for Arch on CachyOS. After an update when I click on my default profile in the selector, I get greeted with a completely fresh Firefox install. There's no extensions, it's not logged in to my account and no browser history. The edit profile button shows a pop-up ''"Firefox is already running but not responding--"''. If I try to switch profile via the Account button on top, I get another pop-up stating ''"Your Firefox profile cannot be loaded. It may be missing or inaccessible."'' I do not have the clean session after closing Firefox set on. I followed the instructions to see if I can restore or recover my profiles. * I can find three profile directories under ''$HOME/.cache/mozilla/firefox'' * In $HOME/.config/mozilla/firefox there are matching linked directories for the profiles * The broken profiles seem to have broken link, ie. no target in /run/user/1000/psd/<profile> is not found Searching for the profile that should be under /psd/ doesn't seem to yield any results, meaning it's been wiped after the update.
