Hi, the developers are gathering information on this odd bug to try to figure out what might be causing it.

Was Firefox 111 able to interpret your cookies database normally, or was it corrupted and unusable in Firefox 111?

See:

• /questions/1410735 Firefox update from 111.0.1 to 112 set the dates of most cookies into the far future and keeps doing it

You can try to clear all the cookies

• https://support.mozilla.org/en-US/kb/delete-browsing-search-download-history-firefox

If clearing cookies doesn't help, it is possible that the cookies.sqlite file in the Firefox profile folder that stores the cookies got corrupted.

• rename/remove cookies.sqlite (cookies.sqlite.old) and when present delete cookies.sqlite-shm and cookies.sqlite-wal in the Firefox profile folder with Firefox closed in case cookies.sqlite got corrupted.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).

• Help -> More Troubleshooting Information -> Profile Folder/Directory:
  Windows: Open Folder; Linux: Open Directory; Mac: Show in Finder

There is a new update to resolve the future-dated cookies bug:

• Update Firefox to the latest release
