Firefox sometimes forgets all site sessions over restart

Sometimes, after restarts, FF forgets every site I'm logged into. Open tabs persist, the login sessions do not. I have no better observation of when this happens, I'm afraid - it's not every time. Because of this it's very hard to reproduce reliably - over the past 2 weeks, it didn't happen and now it was 2 days in a row. "Clear cookies and site data" is definitely off. I have no extensions apart from Dark Reader and uBlock. Because my daily work requires me to use a dozen sites I have to log into, all using 2FA, this is incredibly annoying. I have also completely reset my profile, which did help for a while but then it started again - so I'm thinking the profile reset was more of a coincidence than actual causality.

Sounds like Firefox isn't saving all session data (cookies) when you close Firefox. Is this about tabs you want to keep across the session or merely about the website remembering you?

Use one of these to close Firefox if you are currently doing that by clicking the close X on the Firefox Title bar, especially if you have multiple windows or Private Browsing windows open to prevent losing tabs in unnoticed windows.

  • "3-bar" menu button -> Exit (Power button)
  • Windows: File -> Exit
  • Mac: Firefox -> Quit Firefox
  • Linux: File -> Quit

You can check "History -> Restore Previous Session" and "History -> Recently Closed Windows/Tabs".

This is about website sessions / cookies / local storage / something like that - websites remembering me. Keeping tabs open works fine (otherwise, I'd probably have switched browsers immediately, I'm depending on that feature).

What really drives me insane is the seemingly random nature of when this "bug(?)" occurs, if it was reproducible, I at least would have something to work with...

Hi,

What extensions do you have? Is there a chance that one of them interacts with cookies (and maybe does something wrong)?
