UPDATE
It turns out I didn’t lose all logins in Firefox, just a couple of major ones. It was very surprising. And this was after losing all in LibreWolf, so I thought it was all in Firefox, too. My bad.
As pointed out in the comments, LibreWolf is basically “Private Browsing Mode” by default. I did not know that. I turned that off, re-copied my profile, and I’m good to go.

I just installed Librewolf (Flatpak) the other day, here’s the sequence of events:
- Install Librewolf
- Run it once and close it.
- Copy the contents of my profile folder from Firefox to my new profile folder in Librewolf after deleting its default contents.
- Run Liberwolf and see that everything is good: bookmarks, logins, extensions, etc.
The next day I run Liberwolf and notice I’m logged out of every website that I normally keep logged in. I figured I probably failed to change some default privacy setting in the new browser and it wiped my logins.
So I open Firefox and I’m logged out of every website there, too! I still have all my bookmarks and such, so I know I didnt move my profile contents by accident.
What in the world happened? Why did I suddenly get logged out of everything in both browsers?
OpenSUSE Tumbleweed with btrfs.


Depending on which accounts we’re talking about some services like google use a rotating session identifier where if it rotates while in one browser and you open another browser using an older version of same session token it’ll kick you out because it’s expired. I know it happens if I rollback a snapshot of my profile even just like 24 or so hours. But ALL accounts, yeah I’m not sure there either
This has never happend before. For example when I migrated from Windows to Linux I had no issues copying my profile. It’s still active in Windows which I occassionally boot. Same with copying my profile to my Steam Deck.
That makes me wonder… I should go boot my SteamDeck to desktop mode and see if my profile there still has active logins. Windows, too.
