Firefox Community Forum

BT yesterday misspelt my email address with an additional 'h'. Although the original address has now been restored, firefox will no longer accept the original version (displaking a red sticker saying 'email address or user name misspelt') and I can only read my emails using on my Windows laptop using Microsoft Chrome. As I dislike having anything to do with google, please can someone explain how to resolve this problem (by removing cookies or whatever else).

Many thanks,

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 !

I deleted coockies and since then (even though the Settings appear correct) every time open a web site I hace to accept cookies and re enter my log in. Nothing is rememebered. I evern have some sites opening blank (without my saved options) but on my home computer the same user name and password displays the data that i missing on my work computer. I exported passwords, deleted and re-installed Firefox but there is still the same problem.

Help please!

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 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.

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.

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

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

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

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.

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?

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.

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!

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.

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.
