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?

I am following all the online instructions I can find to turn off private browsing on Firefox - in Privacy and Security by clicking on 'Remember History' for example, and also restarting laptop - but it is not working and I must constantly log back into all my accounts and websites, including my e-mail account. I need assistance with specific and exact instructions how to remove private browsing and explanation why not working what I have already tried. Thank-you for your assistance.

Recently, websites (e.g., YouTube) have stopped keeping me logged in. I've already checked all the security and privacy settings, but haven't found anything that seems to be causing this.

I hope someone can help me. It's really annoying having to log in to all the websites every day.

Hello, I encountered an issue today where, upon starting my PC and opening Firefox, I found that I had been logged out of every website. My bookmarks, browsing history, and extensions are all still present, and I am using my usual profile. However, all active login sessions were cleared. I haven't changed any privacy settings recently, and I'm wondering if this is a known issue following a recent update or if it indicates a corruption in my profile's cookie storage. Could you please advise if this is a "normal" occurrence or if there are steps I should take to prevent this from happening again?

I look forward to hearing from you. Best regards, Luka.

I have Firefox set to "Delete cookies and site data when Firefox is closed" and also "Clear history when Firefox closes" (with everything set to clear except site data).

Then I have an exception list of sites to save cookies and site data for (for example, youtube.com).

The problem I have is that not all of the cookies are deleted when I exit. In addition to the sites on the exception list, there are others not on the list that remain.

For example, in the screenshot, this is a cookie from gleam.io. It's setting it for domain .youtube.com, and this is one of the cookies that remains. I believe it's remaining because youtube.com is on the exception list. However, it should be deleted because it's for the gleam.io site. If I check the browsing data in Firefox after restarting, it shows up as site=gleam.io.

Furthermore, I question whether the cookie should be allowed in the first place, since I have Strict Tracking Protection enabled, which should disable all cross-site cookies.

I don't know how to fix this in Firefox.

Google sent the following message when I tried to open a Youtube video.

I need to find how how check if cookies are enabled on my Firefox browser

Why are you NOT clearing browsing data. I click on clear browsing data. Temp Cached files goes to zero. When I open a new browser that data still remains. I insist that you clear data for real not just for show!

Hi, After the latest update, I experienced unusual Firefox behavior. When I turn off PC Firefox signs me out from all sites and when I open them it also requires me to accept cookies again (on any site, even when I visited it in the previous session). I thought that the update accidentally turned on the option to delete cookies after closing Firefox, but I still have this option unchecked in settings. I can also still se all my previous cookies in settings. Passwords are also still saved in Firefox password manager. The PC is new (3 months) so I don't expect it to have memory problems.

Should I go back to the older version of Firefox? Any help will be appreciated. Thanks
