Firefox 18 not keeping persistent cookies.

This also happens in FF 18 - cookies that are supposed to be retained are not.

I tried the SQLite Database Browser tool, but found no questionable entries like the ones outlined above.

I tried deleting site preferences - no change. Tried deleting permission.sqlite. Still no change.

What this is showing up in is my online banking. It asks you to register the computer, and supposedly puts a "secure cookie" in the browser. This no longer works - everytime I have to go through the process of asking for a new code via email. This works fine in IE, and used to in Firefox. What is odder is that if I ask it to show cookies, it shows it with an expiration of Jan. 2100. But it does not seem to be accessble to FF anymore, while it used to be. Any other ideas?

It is possible that the cookies.sqlite file that stores the cookies is corrupted.

Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete other present cookie files like cookies.sqlite-journal in the Firefox Profile Folder in case the file cookies.sqlite got corrupted.


Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe mode start window or otherwise make changes.

Renaming the cookies.sqlite file, allowing FF to create a new one, solved the problem. Thank you very much!
