While checking email for one account, I keep getting an "HTTP ERROR 400" message saying "Problem accessing/service/preauth. Reason: auth token expired.

I can Refresh FoxFire and the problem goes away for that session, but the next time I go to that sight to get my email, I get the same error message and have to Refresh FoxFire again. Refreshing is not a big deal, but it screws up all my settings, and I have to go back and reset all the options. This problem used to happen about weekly, but now it is almost daily.

Chosen solution

This issue can be caused by corrupted cookies or cookies that are blocked.

Clear the cache and remove the cookies from websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).

"Clear the cache":

  • Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

"Remove the cookies" from websites that cause problems.

  • Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"

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

  • Rename/remove cookies.sqlite (cookies.sqlite.old) and if present delete cookies.sqlite-shm and cookies.sqlite-wal in the Firefox profile folder in case cookies.sqlite got corrupted.
