Firefox keeps randomly logging me out of certain sites overnight

[Red Squirrel]

This has been happening ever since I did a clean install. I'm on Linux Mint 19 Cinnamon I think... whatever was the latest a few months ago.

Basically when I go to bed and I come back the next day I will find that I've been logged out of a bunch of sites, but not all of them, it's very hit and miss, and VERY annoying. I thought it was maybe Facebook Container extension that caused it, but I disabled it, and it's still doing it. I don't really have that many extensions, and I've always had these same extensions before and it never did this. Ublock and Privacy badger. Anything I can do to stop it from doing that? Even if it's left running it still does it.

I think I experienced this problem a couple of months ago. I dimly recall it was related to some privacy changes that they made.

Try going to about:config and change the setting for privacy.purge_trackers.enabled to false to see if this makes a difference.

It probably starts with v75 since March 2020

Someone said he has to delete profile to make it work.

So that extension did not work unfortunately. And it's not ALL cookies that are being deleted, it's just some. Like I never lose my login for AT for example, but I lose Youtube, Reddit, Facebook etc. It seems to be hit and miss too, sometimes I can go a few days, but lately it's been more aggressive and happening every single night.

I'll try to set purge_trackers to false and see... though I hate that it can't just purge the trackers without actually killing the login session. Ex: make it stop tracking me on other sites but if I go on that actual site then still keep the cookies.

I got 2 copies of Firefox installed, one is normal C:\Program Files\Mozilla Firefox installation and the other is from PortableApps.com under a portable drive folder.

When I tried to install Forget Me Not add-on on the normal version, it would not let me click the icon on the toolbar, it was dimmed, and another Multi Account Container add-on even though is installed, it won't show it's icon on the toolbar, yet the portable version worked fine for both add-ons.

I had to create a new profile and delete the Default profile to make normal version of Firefox to have both add-ons to show properly on the toolbar.

Firefox probably is really bug-ridden, I guess.

Yeah guess I will try another profile. I already have multiple clean profiles I use for when I want to test stuff such as multiple users into an application so I logged into FB on one of those just to see if it stays logged in tomorrow. Though that profile has zero extensions so if I do make a new profile I'm still going to want to use adblocker etc. Hopefully it's not one of those causing an issue. I've used those extensions for a long time though so it's weird it only started this now.

This seems to have magically went away... not sure if that extension I installed is working, maybe it just took a while to kick in.
