firefox not deleting cookies after close
Currently using Firefox 36.0.1 - but I'm not sure if it started in the previous version as I recently updated.
Pertinent settings in Options --> Privacy
Firefox will: Use custom settings for history Always use private browsing mode - disabled Remember browsing/download history - enabled Remember search and form history - enabled Accept cookies from sites - enabled Accept third-party cookies: From Visited Keep until: I close Firefox
Despite the last setting above, cookies are not deleted after Firefox is closed. Previous versions would delete these cookies upon close

Make sure that you close all open tabs before closing Firefox to prevent Firefox from storing the cookies in sessionstore.js as part of the session data.

If clearing cookies didn't help then it is possible that the cookies.sqlite file that stores the cookies got corrupted.
- Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete other present cookies 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

Is this a new requirement for 36? I have not previously had to close all the tabs for this option to work. This would seem to be contrary to the option to Show my Windows and Tabs from last time when Firefox starts.
I'm assuming Safe mode disables all the extensions. Should it also delete cookies on exit? I.e., if I repeatedly open and close Firefox in safe mode, this would eliminate all interference by add-ons (I don't use other themes). and remove cookies on close?
So far manually deleting them has been the only way.
Installing 35.0.1 resolved this problem (all other settings/add-ons being equal).
