FireFox does not save cookies

Since I installed a recent update of FireFox 3, cookies were not being saved after a browser session ended.

While there seem to be different causes, if you’re on Windows and using AVG, the file that contains cookies may be locked by AVG for some reason. Deleting that file or disabling AVG to scan cookies may help.

FireFox saves cookie information on Windows in:

[DRIVE]:\Documents and Settings\[USER]\Application Data\
Mozilla\Firefox\Profiles

The file is named cookies.sqlite.

If you delete it however, you’ll have to check quite a few “remember me” boxes in the near future.
