Comment 8 for bug 1082446

I think I have the same problem. I am on Linux with this Firefox (FF) profile since ages. Using the binaries (local: de) from the mozilla website. Updated from 16.0.2 to 17.0 by manually downloading a new binary, deleting the old fox, extracting the new one (since the FF updater said I already have the newest version - which was wrong).

I use the userdefined privacy setting with cookies expiration set to "ask me every time". I always use the "remember this" checkbox, so I am only prompted on first visit of some page.

This is the experience (which I successfully reproduced by restoring the backupped profile from 16.0.2):
Right after the first start with 17 I visited two websites which I frequently visit (so cookie acceptance rules are stored). On both visits FF asked me if I want to accept cookies. I accepted with the remember checkbox checked. Closed FF. Started FF again, visited the pages again: FF asked me again.

If I "mv permissions.sqlite permissions.sqlite.old" and start FF afterwards, visit some website, accept. Exit FF. Then a new permission.sqlite file is created and the settings are remembered (if I start FF again and visit the websites I am not prompted).

So, as mentioned elsewhere, it seems that my FF17 is really not happy about some rules in my permissions file which was accepted by FF16 without any problems. I never edited the permissions file by hand. The workaround which involves deleting the permissions file to get a new one is not really a workaround since that means I would loose several thousands of permissions entries. I am afraid, I cannot post the apparently broken permissions file here since it contains (obviously) personal information - all the sites I visited. Hope you can get FF17 a bit more fault tolerant (like the versions before were).
