Windows 11 Home 64-bit

For the last couple of days, FF has been signing me out of all social media sites and some other sites that are open in tabs also. I'll go back to the tab, and be signed out when I was signed in 5 minutes ago. Google, FB, Reddit all have this problem and some streaming sites. I had changed my settings to clear all data when it was closed, so I thought that might be it, but I changed it back and restarted FF and the computer and it's still doing it. Haven't tried another browser yet.

I changed nothing in settings, and doubled back and checked, still set to open windows/tabs where left off, and not to delete site data/cookies when closed, but every time I open the app, nothing, no history, no tabs, have to re-sign-in to everything. Why might this be, as it didn't seem like an update happened in line with this occuring, or anything at all for that matter that would change how things behave.

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

System: Windows 11 Pro 25H2, Firefox 146.0 (20251205151434), I don't use any Add-ons

I manually clear all youtube cookies. I have these youtube exceptions. After going to youtube, then checking "Manage Cookies and Site Data" I still see Firefox saved a youtube cookie.

Thank you

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.

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.

Just a question. When I clear the browsing data I always use the same options and clear from 12AM. The result is I have anywhere from 12-22 MB of remaining data. Why is there a difference?

This Help Article: ( [|"Manage local site storage settings"]) says: Allow or block websites from storing information "You can set up Firefox to always allow or block specific sites from storing information. You can also allow a site to store only for a single session. "

So I added a URL into 'Cookies and Site Data' > 'Manage Exceptions' with the option "Allow for Session". But it appears to have no effect. The site's cookies and data don't disappear from the "Manage Cookies and Site Data" window after Firefox is quit.

Does "Allow for Session" mean that a site's cookies and data will be deleted when Firefox is quit? If yes, the feature is not working ... in my version of Firefox which is 115.32.0esr. Or, am I missing something? I have "Enhanced Tracking Protection" set at "Strict", if that has any relevance.

Thanks !

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 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.

I'm trying to log into my gmail account, but every time I try, I am sent to the clear cache and cookies page. I have cleared my cache many times and still am unable to access my email on my computer through firefox. Can I get help with this? Thanks in advance!

While attempting to change my password in my TrendMicro antivirus, it was suggested that I clear my Firefox "Cookies & Site Data" and I cannot find that option in Firefox. How do I accomplish this task presently--it used to be so easy.

Hi folks

I have a particularly infuriating problem. A few weeks back, Firefox stopped displaying my usernames and passwords whenever I wanted to log into a site. This coincided with my installing BitDefender, although I don't know why.

Through googling I eventually realised I could go into about:config to fix this. signon.rememberSignons displays as false, when I turn it to true it fixes the issue.

But here is the problem I can't solve. Everytime I restart firefox or my PC / Mac (I am using both, with a syncronised account on both windows and MacOS) it sets signon.rememberSignons to false AGAIN. Which means every single time I browse I have to go into about:config and fix this. Maddening.

Please can you help?
