Cannot login with Firefox Mobile (Android)

Bug Report

Platform

Operating System: Android 9
Browser: Firefox Mobile

What is happening and/or broken?

Periodically, after having logged in previously with the "remember me" option checked, Tildes will forget who I am. When attempting to login with a valid username/password, the message "Page expired, reload and try again" is displayed, and login fails. Reloading the page does not resolve the issue.

This has happened several times over the last few weeks. Each time it has resolved itself within about 24 hours, with the site suddenly "remembering" who I am without having to log back in.

Opening a Private browsing tab in Firefox mobile does not resolve the issue. Logging in via Desktop continues to work even when the mobile version does not. Logging in via the Duck Duck Go mobile browser does work even when Firefox mobile does not. This seems to only happen on Sundays?
