firefox just lost all open tabs (even pinned ones), history (for this device only), open windows

on PC A, firefox just lost all open tabs (even pinned ones), history (for this device only thank gods), open windows.

I installed a windows yesterday on a different PC (lets call it B), and logged in with the same microsoft account PC A uses. Then installed firefox and logged in to sync (on PC B).

Did that somehow overwrite the profile? Even though it was a different PC?

Mystery solved.

"Clear history when Firefox closes" was checked. Needless to say, I didn't activate this, this is slightly terrifying to think that it's possible to do something in firefox and this can lead to that option getting activated.

Maybe there is a keyboard shortcut and my cat managed to find it? No idea. But this option needs to be protected behind a "are you sure?" popup.
