Firefox Community Forum

One of the recent updates changed Firefox's behaviour. It now remembers my login status to various sites when I close the browser. For example, if I was logged in to facebook when I closed the browser, I will be logged in when I open the browser and navigate to facebook.com. This was not the case until very recently (a few weeks at most). Is there a way to change this?

I have strict privacy settings, and Firefox should delete all cookies when it is closed. There are no 'exceptions'. I have 'always use private mode' checked for history. Also: I haven't changed any settings recently - something changed in Firefox.

Any advice? Thank you.

I recently noticed that my Microsoft account remains active after I sign out if I press the back button. All my personal and account information is still displayed, indicating that the account is still signed in. I even tried clearing all browsing data and history, but that didn't resolve the issue. This doesn't happen with my Gmail account, nor when I access my Microsoft account using Edge or Chrome.

I understand that closing the browser likely signs me out, but I have no way to confirm that unless I check for active devices in my account settings. Can you explain why this timeout issue occurs? It seems odd, especially since Mozilla prioritizes security and privacy.

When ever I shut down browser clears history and most importantly signs me out of all my accounts making me to sign in for every account I have. I need to stay signed in all my accounts.

When I try to log on to a particular web page using my password, I get an error page. When I do so using the Private browse function it works. Following is the error I get: {

 "callId": "019a1701de257ed0a722da6257f2896e",
 "errorCode": 403005,
 "errorDetails": "Unauthorized user",

 "apiVersion": 2,

}

Does anyone have any great ideas??

This may seem like an old problem, but I seem unable to fix it. I have a web site for which I updated the home page. But when I tried to have Firefox load the home page from the web site to be sure it looks OK, Firefox loads only the local copy from past loads of the home page and I do not see the updated page at all. I have tried clearing the cache, but that does not fix the problem. It seems that something has changed as this method, if I recall correctly, used to fix the problem. I am sure the fix is simple, but it has eluded me. Can anyone share the fix for this? I currently use Windows 10.

A few days ago, my Firefox browser stopped clearing browsing data, cookies, history, cache. I am using a custom-built desktop computer with Windows 10 Home, Firefox v. 143.0.4. What is the setting I need to change so this will start clearing data again? The "Clear data and cookies" no longer works, and my search has brought up no other options that I have found. I need simple instructions, please.

How do I turn on cookies for firefox so I can watch youtube videos, I never had this problem for the 6 years I've been using this laptop but all of a sudden google say's my cookies is the problem.

ブラウザゲームサイトUnityroomなどでゲームを遊んでいると、Cookieの容量が10ギガバイトを超えることがよくあります。 どうやら10ギガバイト以上のcookieをFirefoxでは保存できないようです。 FirefoxでのCookieの容量を10ギガバイト以上にしたり、ページごとに個別に管理できるようにしてほしいです。

heres what the error page says:

" We've detected a problem with your cookie settings. Enable cookies

If you have cookies enabled but are still having trouble, clear your browser's cache and cookies. Adjust your privacy settings

If clearing your cache and cookies doesn't resolve the problem, try adjusting your browser's privacy settings. If your settings are on high, manually add www.google.com to your list of allowed sites. Learn more"

cookies are enabled, i whitelisted google and youtube, i clear cache. the only thing that works is if i clear cookies for youtube, but then i have to sign in again. and this is reset next time i open firefox.

I have FireFox set up to reset every time I start a new session which causes DuckDuckGo's AI search to reset every time. Does anyone know how I can set it so it doesn't do that? It's annoying always having to disable to every time I open a new session.

As has been mentioned many times before I am sure, it would be really helpful to be able to have a less laborious way to add exceptions but as I have been through the ridiculous process of typing in site addresses manually one by one without having any sensible way to record these addresses already I guess it won't help me now. The ridiculous aspect came from having to take screen shots of the list of sites from the manage data list after deleting everything not wanted, scrolling down a windows worth at a time, copying that screen shot into multiple copies of a graphics program then shrinking each copy of the graphics program and Firefox so each can be seen so I can manually type each address across.

I know I am supposed to be nice but this is just insane. It is 2025. There is a thing called copy and paste. Apparently some people at Mozilla are not aware of this.

Having got that off my chest the next issue is that the deletion of cookies and data only occurs when Firefox is closed. Who closes Firefox? Why would you close Firefox? I currently have 24 tabs open. Why on earth would I want to close them down just so they have to be selected one at a time and reloaded? What is the thinking behind this stupidity?

The only time I close Firefox down is when Windows is restarted for updates (every application) or when IDM needs to update as I found this negates the need to restart Windows (Firefox only).

Other than those situations I am trying to work out how to fit this cookies/data deletion into the normal operation of my computer. There appears to be a lack of a suitable way to deal with this situation. Would it be considered acceptable to just wait for those times Firefox has to be closed? This would be far better than what I have been doing up to now but why wouldn't Firefox delete this data when the last tab for a site is closed? There are a huge number of sites I bring up due to searching for something and close them immediately or after reading what they have to say.

I have been using computers for about 30 years and have long lost the inclination and to be honest the ability to delve deep into them. Today I just want to have them do what I want/need without unnecessary complications.

Have I got this situation right or is there something I have missed? At the moment IDM has been having a lot of updates thanks to YouTube's greed but before that I found I generally only had to restart my computer for MS updates and when strange things started to happen.

I used to be able to clear all data with no problem, but now it's holding to Gmail login data (I think that's the problem, anyway). I clear all data after each browsing session and have been doing so for a long time, but it's not working anymore. But it is working on my husband's laptop and we're on the same version of Windows (11) and have the same settings. Can someone please assist in figuring out what's happening behind the scenes? Thank you!
