I-Firefox Community Forum

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 don't recall clearing the history.

Also, starting a few days ago, if you type it into the search bar on the homepage, it will drop to the top. What is the cause of these issues? I'm using Windows 11.

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

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 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

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?

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.

good morning,

I am having problems using a third-party website, playing chess, and one of the functions on their website is not available to me because I keep getting an error message. they have a forum on which I am discussing this issue with one of their Mod's, and he seems to be under the impression it has something to do with my Browser (Firefox 115.32.0esr) storing site data, and that the file in which this is stored has become corrupted in some way. I have no idea how he arrived at this conclusion but that is what he said.

I assured him that, "in Firefox, under <Privacy and Security>, in <Cookies and Site Data>, there is an option marked: "Delete cookies and site data when Firefox is closed." this has a tick box next to it and on my computer this has been selected for about the last five or six years. the browser does not retain site data or cookies and deletes them each time it closes. when I follow the instructions you linked to, and click <Manage Data>, there is no data to manage. it does not exist."

however, he replied to this that: "I don’t think that setting deletes Local Storage, though I’m not 100% certain."

one observation I make is that when I open the <Cookies and Site Data> <Manage Data> dialogue, the websites I have visited in the current session are listed. this data therefore does exist, and there must therefore be a file, even if only temporarily, containing this data. my question is about what exactly happens to this file when I close the session.

1) is the file emptied of data, but still exists as a file.

or

2) is the file physically deleted so that it no longer exists.

if, after the session, I reopen the browser and select the <Clear Data> dialogue and click <Clear> does this simply empty the file or does it physically delete the file. if the file still exists, is there any way to ensure that it is physically deleted in order to confirm that it is not corrupted in some way?

thank you.

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.

using linux cinnamon, have to continuously sign in to my sites. I didn't have to do this before. what can I do to stop the cookie deletion or whatever is causing this??

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.
