Firefox

I don't know if this is a Firefox or Google issue tbh, but I'm getting signed out of Google more than once a day lately for no reason and this is getting really annoying. Is anyone else experiencing this?

Edit: I was able to narrow down to Nodium. As I visit a medium website with the extension enabled, I need to sign in again to Google. It seems they're a bit sloppy when deleting medium cookies.

Yesterday I checked if there were unknown devices in the security dashboard, but everything seemed alright. The supposedly signed out devices still show up as active sessions, which leads me to believe something's up between Firefox and Google.

And it's only happening with Google, for both accounts that I use. I disabled some extensions that could be getting in the way, but that didn't help. There's also no "you were signed out message", yesterday I was even using Google Meet when it happened and I just got kicked out of the meeting.
