Since last week there is a cookie that I can not remove in the Manage cookies and website data panel. It is called about.ef2a7dd5-93bc-417f-a698-142... There is probably more but that is not shown in my view. How can I remove that?

so i installed the atarashii extension, but it didn't work for me, so i deleted it, then rebooted my pc to notice that it's running, and i can't unistall it, i disabled it but for some reason it still works

VPN has been working like a charm...today I go in circles...it asks me to sign in...ok...screen says go to open screen and open VPN...I click there but VPN takes me back to the original screen coming up first time today.

Wenn ich im Suchfeld etwas eingebe, kommt immer dieser Fehlercode und ich müsse mich an den Administrator der Webseite melden. Obwohl ich sämtliche Virenprogramme verwendet habe und den PC mehrmals runter- und wieder raufgefahren habe, kommt immer wieder dieser Fehler.

I have Firefox 15.3.0.1 on two computers. One one, when I go to about:config, there is a search bar with an option to "Show only modified preferences." On the other computer this search bar is missing. How can I make it display on the second computer?

When I download an update and restart firefox, it opens a https://www.firefox.com/en-US/whatsnew/ tab. I want it to not do this.

Good Day.

I have encountered a problem recently with on particular forum site.

When I attempt to login I receive an error after pressing the submit button. 

The form displays this error "The submitted form was invalid. Try submitting again."

I have been using the site regulary for several years and have never had this problem

The following is what I am using:

    Firefox ver 153.0.1 64 bit
    Windows 10 and/or Windows 10 (yes this is happening on all 3 of my PCs)

The forum site is using phpBB Forum Software. I do not know the version. As stated above they have been using this software for several years.

In trouble shooting this issue I have discovered that if I do the following in the specified order I can login and create and respond to posts and Private Messages. But as soon as I log out I receive the invalid form message until I do the following steps again.

            1) Clear all cookies, temporary cache, site settings, browsing and download history, site settings
               and saved form info.
            2) Shutdown Firefox 
            3) Navigate to my profile with Windows Explorer 
            4) Delete the file cookies.sqlite

I must do this each and every time I access the site.

I am at a loss as to what to do about this. Does Firefox have any error logs or console logs? If so how can I enable them to see if I can get a better idea of what is happening?

Thanks in advance for any help with this.

I would like to know whether this is a normal process that happens when using firefox browser or has my version of the app been compromised? Or should I allow this to be accessed?

Subject: Help recovering old Firefox Sync data using my Recovery Key

Hello Mozilla Support,

I’m trying to recover my old Firefox Sync data, especially my bookmarks and saved passwords.

I still have an Account Recovery Key that I saved on August 27, 2025. However, after signing in to my Mozilla account today, my account page shows “Account recovery key: Not set”, and syncing does not restore my old bookmarks or passwords.

I may have reset or changed my Mozilla account password today without using the old Recovery Key during the process.

Could you please confirm:

Is there any way to use my old Recovery Key now to recover the previously encrypted Firefox Sync data? Is the old Sync data still retained on Mozilla’s servers in any recoverable form? Is there any other recovery procedure available for bookmarks, passwords, or previous Sync data?

I still have access to the same Mozilla account and the original Recovery Key file. I will not send the Recovery Key itself unless there is an official secure procedure that requires it.

We recently had an update on our printer drivers and somehow this has swapped settings from the previous system print dialogue to "Firefox - Print". The Firefox print dialogue does not have print preview and I need to be able to see a print preview. I've noticed that this was an issue in the past and people have solved it by going into about:config and setting print.tab_modal.enabled to false, but this hasn't worked for me. I am asking this question because if I can't find a solution I will have to switch to Chrome so I can see a print preview and I would rather not. If there is another way to force the system print dialogue instead of Firefox, please let me know.

Every thing will be working fine? And then I click on something, and it takes a long time. And then at the top of my prompt, it says Mozilla firefox is not responding. I've been dealing with this for some time now. You can't figure it out. This is happening on my computer. Also I would update it the program and the very next day.There's a prompt asking me to upload again. I upgrade, and then I still get the same thing.Mazilla is not responding.

this issue has arisen suddenly over the last month. so i try to load bandcamp and for a few moments i'm able to go from page to page. after a certain short amount of time has passed between me opening the site and using it, just seconds, upon me clicking a link, pages initially appear to load [the refresh button switches to the X icon] before they quickly halt and keep me stuck on the same page. attempting to open a link in a new tab in this state gives a blank page - not showing as about:blank in the url but the intended destination. sometimes when i try to confirm a change on something i have uploaded to the site or try to log in, bandcamp gives an error reading "There was network error. Please try again."

so i originally thought it had something to do with using a VPN; initially i thought it was alleviated when i turned it off but i was wrong, problem soon reappeared. i've actually been using zen browser for a while, so maybe it was localised to that? i switch back to regular firefox and it was there too. troubleshooting mode didn't yield any difference either, so there's no conflict with extensions... clearing all bandcamp site data hasn't worked either, now because of this issue i just can't log back in lol. i ended up testing on a non-firefox browser, microsoft edge, and found that this issue isn't present there. so i'm kind of stumped on how to figure this out by myself now. keep in mind this is the only website that is affected by this issue

When I drag a URL from the browser to the desktop, clicking on it triggers a prompt, saying "Do you want to open this file". If I look at the general tab in the properties of the link, it says "This file came from another computer and might be blocked to help protect this computer". This happens on both of my windows 10 computers since they upgraded to the latest version of Firefox (153.0.1.) I need to check the "unblock" option in the link properties to unblock the link. This does not occur with other browsers.

The recent changes to the right-click menu on YouTube are a backward step. The menu is now cluttered with options I don't use, while the useful “Open in New Window” option has disappeared. I regularly use this function and having to use Shift+click instead is unnecessarily inconvenient. Please consider restoring “Open in New Window” to the context menu. Not every new feature is an improvement, and sometimes the simple, familiar options are the ones users actually want.

When Firefox is running in a non-maximized window, an unwanted empty space appears on the left side of the tab bar, before the first tab.

This space is not present when the Firefox window is maximized. It appears automatically whenever the window is restored to a smaller/non-maximized size.

The issue affects the tab bar layout and leaves a noticeable unused area on the left side of the tabs. I would like to know whether this is expected behavior or a UI bug.

Firefox version: 155.0 64-bit Operating system: WINDOWS 11 25H2 64-bit
