When I close my browser, my session with Google, Facebook and occasionally other sites is broken. The current work around to fix it is: Settings -> Clear Cookies & Site Data -> type in google.com & youtube.com - remove those (see attached screengif) So far I've tried: '''Creating a new profile''' I previously had a Firefox profile called "default" for many years. It served me well, after this happened everytime I restarted the browser, I created a new one called "Tim". The problem persists. '''Clearing my cache''' As mentioned - this works right up until I restart my browser. '''An idea I have''' Something weird is happening in the cache. If you see my second screencastgif - by clearing my google cookies and cache, apparently the size of the cache drops by 900mb. That's not plausible really, and it seems to be consistently happening every time I do this. In fact, the large number seems to be going up every time. It makes me wonder if somehow, older cookies or cache are being reintroduced everytime somehow? Is that possible? I'm somewhat technical but I haven't been doing weird stuff with my browser or tinkering much - I'm using Debian 11.5 with Firefox 102.3.0esr (64-bit) from Debian packages. I have a few extensions like ublock and firefox containers but far from overkill. I'm happy to open sqllite files in DB_Browser_for_SQLite if it'll help. My cookies.sqlite seems? to be in good? condition? Any sense of where to go hunting this down?
