Firefox Community Forum

I have noticed for quite a long time (>1 year) that even though I have this setting correctly enabled to delete cookies and cache when closing the browser, when I reopen the browser, even after a computer restart, the data is still there. I have to manually direct the browser to delete these items for it to ever get rid of them.

I have spent countless hours looking at the same settings, all correctly enabled, yet this feature just will not work. I am fully current with the latest updates for the browser and computer. I have checked, and double checked to make sure I don't have anything listed in the 'exceptions' list. It is, and always has been empty. Using Win11 Pro desktop, current version of FF is 146.0.1 (64-bit) as I write this.

Seriously, what is going on? I even switched to another browser for a while and that browser's settings worked just fine and deleted all cookies and cache when closing.

Recently, Firefox has started making me log into my "keep me logged in" sites such as facebook, slickdeals, etc. I've tried changing setting to not clear history. But still every time I close Firefox and open it back up, I have to log into those sites again. Any help would be appreciated.

For a couple of days now my cookies have been getting deleted or corrupted every time I turn off and back on my computer. The only temporary solution I've found have been to delete my cookies.sqlite file, copy cookies.sqlite.bak and renaming it to cookies.sqlite. It is very frustrating to lose all my extensions, my cookies, my bookmarks and logins to my usual websites. I am using Firefox version 146.0.1, on a Windows 11 computer running version 25H2. Also, my original cookies.sqlite file is 512kb while my backup is 2048kb exactly, if that is useful in any way. How can I fix my issue?
