Login required each time

(About) each time I open a https://www.pathofexile.com/ page (forum page, trade page, etc.), it requires logging in (again). Something has changed? Formerly (about a few months ago) this was not the case. It "forgets" my password (my session, I guess). Despite that in Firefox, all cookie storage is allowed (for https://www.pathofexile.com).

If the pathofexile site starts "not recognizing" me, then the next step will be: it will not recognize me anymore? (Cannot login anymore?) It seems dangerous.

Not able to reproduce.

If you use a different browser for a week, do you have the same problem? If not, you're likely looking at 1) an extension misbehaving, 2) a setting of some kind, or, 3) a corrupted Firefox profile.
