Every time I manually update firefox, it reinstalls the automatic update malware "Mozilla Maintenance Service". I can't stop this malware from being installed with my browser every time I update Firefox. I call it malware because its not wanted, and it behaves like malware by secretly downloading content without my consent and then shutting down my browser when it finishes by blocking access to all new tabs.

I've tried adding policies to stop auto updates, but Mozilla Maintenance Service ignores all policies. I'm going to see if I can contact AVG and explain to them that Mozilla Maintenance Service is malware and see if I can get it classified as such to see if that'll finally get through to someone because I'm sick of this crap constantly being installed and forcing things on me whenever they want and not when I want.

Now after this update, every google search forces open my location service trying to force me to give location rights. This update is even more malware than all the other updates before hand. Firefox is getting extremely dangerous.

Firefox is screwing my display with a screen logging warning message. Removal instructions are 100% useless.

This is so annoying. I’m sure its simples if you’re a techhie, but for muppets its hopeless, I’m desperate for a solution as i cant use Firefox now

Здравствуйте. Я установил сертификаты по инструкции, которая лежит на s.sber.ru/70VQ2B . После этого в мозилле не прогружается полностью окно входа на online.sberbank.ru, не видно содержимого фреймов (сейчас попробую сделать скриншот). В Microsoft Edge работа нормальная. Удаление сертификатов, перезапуск браузера и компьютера не помогли. На других компьютерах ещё не проверял. Посоветуйте, пожалуйста, что можно сделать. Windows 10, Firefox 153.0.3 (64-разрядный).

Since the last update 155.01 I can't use Firefox as it freezes and hangs after 3 - 10 seconds. On Windows 10 , 64 bit. There seems a bug with the last update for Windows 10 users

Crash report: https://crash-stats.mozilla.org/report/index/c0455e29-69e9-4030-8b03-fdf430260909

Not sure the crash report is related to the issue.

The same issue happens to all of my 3 Windows 10 PCs since the update from today.

I have uninstalled Firefox and downloaded again, but same issue happens again.

I cleared the cache also but to no avail

How can I use Firefox again?

I installed a Mozilla/FF GMail Notifier App. I tho't that I removed it as I no longer needed it. It still Notifies me; annoying. But it's not in my Extension List to Remove again if need be??? How can a hidden/invisible App be still operating, that is supposed to be Removed?

Since Mozilla/FF has no option to Delete a Question, I found the answer to the above posted. MY error: It was a Google Linked App, not the one I Removed which did indeed become Removed. Sigh!

PLEASE HELP!

I get the following error message when trying to access Microsoft Outlook.

Something went wrong server Error(/): GetSections returned no conversation history

I've already 1) restarted the computer, 2) cleared my cookies and cache, 3) re-started firefox in troubleshoot mode, 4) reinstalled firefox... none of those fixed the problem.

On Thursday 3rd September 2026 Firefox stopped working. I tried lots of things to get it to work to no avail. Today, 8th September 2026, I had already deleted the Firefox that was already on my PC so I downloaded a fresh copy from the Firefox website and installed it. It ran perfectly for about 30 minutes then I shut it down. 5 Minutes later, a Firefox crash report appeared which I duly sent of. Checking Event Manager a string of error messages saying the same thing, Its the XUL.DLL file that keep crashing! This was the same file that caused the failure last week. I had made sure that XUL.DLL was not on the pc when I downloaded Firefox today. When I click on the Firefox icon it open but stays on a black lower half of the screen and boxes at the top, white lined but black and transparent lines moving left to right across them, eventually it fails and closes, after a few minutes it send the crash report. Its a shame because I have used Firefox for many, many years and now having to use Edge!!!!

I downloaded and installed Firefox. I've set up an account. But nowhere does it show me, or tell me, how to "open" Firefox and start browsing. There is no "search bar/window", just the address window at the top. I'm getting close to deleting the whole thing because it is needlessly frustrating.

Hello, I have formatted my laptop and downloaded firfox, but I'm not able to restore my old bookmarks and passwords after I signed in to my account and sync. Could you help me with this and thank you.

Has anyone reported this before? I am working as a contractor for a BigTech company. I am using an online platform/tool of theirs for several years now but after a recent update the work area doesn't show scroll bars anymore. That means I cannot scroll the editor window and can't go beyond the first page. This makes working (and earning money) almost impossible. As even for the tiniest edit I have to download huge tasks which is extremely time-consuming. An inquiry with my manager there indicated that other contractors on firefox experience the same issue. so they consider it a firefox compatibility issue of some kind. They gave me the advice to use Chrome, Edge or Safri instead. Well, I use firefox because I do not want to use Chrome/Edge... Don't know about Safari but my PC is on Windows... Any idea what can cause it and how to resolve the issue?

Hi I've attempted to disabled the entire new block of 'Stories' but they continue to show up cluttering my screen. Why isn't 'disable' working? How can i get rid of everything except the search window and my single line of helpful links? Gary

I AM RUNNING WINDOWS 10 ON THIS COMPUTER AND I FIND YOUR UP DATES EITHER STOP FIREFOX FROM WORKING OR LOADING PAGES AND I AM TIRED OF THIS...

FIX YOUR BROWSER SO I CAN USE IT OF I WILL FIND ONE THAT WORKS. I AM SITTING HERE WATCHING WHAT USED TO BE AOL'S OLD LOGO MOTION...

''''PLEASE FIX IT OR LET ME KNOW OF A BROWSER THAT WORKS OR I WILL FIND IT MYSELF''''.

Latest Stable Firefox, windows, over 4000 tabs. Overall Firefox works great for me. but when I restart it to install the latest versions etc, it only restores one active/loaded tab per window. Rest are restored, but in a closed/unloaded state. I usually have 5-20 open tabs per window, and hundreds more unloaded, it's how I work. How on earth can I get it to restore all the open/loaded tabs as they were, not in the unloaded state they default to?

Issue still occurs in a new install with no addons, default settings, under 30 tabs etc. Ditto Win 10 or 11.

Also, how on earth can I get official Mozzilla pages to use Dark Mode??

How can I stop Firefox from automatic granting sites cross-site cookie permissions (see screenshot)? The problem is that the cross-site cookie(s) granted for a site more often than not is completely unrelated to that site. This problem is very frustrating.

I have tried changing several settings in Tracking Protection but nothing has stopped Firefox from auto-granting these permissions. I have for example turned off "Fix major site issues (recommended)" but it has not changed this behavior.

Thankful for any help.
