I've noticed for a while that I have to manually log back in to websites frequently even when I check "remember me" to enable permanent or long-lasting cookies. I always thought it was an extension causing the problem, but recently I reinstalled my OS (Arch Linux) and it happens on the latest Firefox (30.0) even with no extensions installed. For one website that exhibits this problem, Hall.com, I even reached out to them about it but they couldn't find any problem on their end. After logging in, there is a rembember_user_token cookie that is set to expire in 3 years. Is this a bug, or could there be anything else preventing the cookie from being stored?


It seems to have been this issue:

Firefox does not remember login information1

It may be due to a corrupted cookies.sqlite file in Firefox's profile folder. In order to fix this, just rename or remove cookie.sqlite while Firefox is not running.

Open a terminal and type the following:

cd ~/.mozilla/firefox/xxxxxxxx.default/
rm -f cookies.sqlite

Note: xxxxxxxx represents a random string of 8 characters.

Restart Firefox and see if it solved the problem.

  • I answered too soon. The issue persists. Could it be the server is invalidating my cookie when my IP address changes (due to proxy)? – Reed G. Law Jul 17 '14 at 7:08
  • It indeed worked the first time I removed the cookies.sqlite. But now (after a day) it's broken again. Removing cookies.sqlite does no longer fix the issue (even temporarily). – Taylan Nov 9 '16 at 6:13
