I am not able to use Mozilla Firefox on my computer. It's the only browser I have been using. When I tried logging in today, I got a pop up the said: 147.0.1 is not compatible with min version 147.0, max version 147.0. Try to reinstall. I reinstalled but no luck. Please help. I need my bookmarks.

I recently wiped & reloaded my computer. Multi-Account containers re-installed successfully & I see all my containers. The issue is with sign-in to Reddit.com website. If I try to login using a container, I get invalid username or password error. If I login without using a container, it's fine. I am copy/pasting my account info. I tried different containers; same issue. Tried creating a new container; same issue. Try again without using a container; login to Reddit is successful.

I love Firefox and generally really appreciate the way y'all operate as a company and developer.

However, I really don't like this new function to add tabs to a group. Since it rolled out, I'm always adding tabs into groups when I don't mean to. Really, it's creating a group almost every time I move a tab around. If I delete the group, it's just more clicks and distractions to deal with.

In the past, when you've rolled out new features like this, you've also made it very easy to turn off any new feature we don't like. But I can't figure out how to turn this off. Is it possible?

Thanks for your help.

Through extensive troubleshooting, I am unable to get firefox to open at all.

I've done a full uninstall, cleaned all user directories, program files / x86, program data, appdata roaming and local, etc. I used the Microsoft uninstaller and even Revo Uninstaller to remove everything related to Firefox, did a restart and reinstall of the latest one and it still won't launch.

Firefox was previously working until a reboot occurred and now it won't launch.

Firefox 32 bit seems to work when installed, and running Firefox as an admin previously worked but no it no longer does.

I looked at the following articles: - https://support.mozilla.org/en-US/kb/firefox-wont-start-find-solutions - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles#w_start-the-profile-manager-when-firefox-is-closed

There's no malware on this machine (business EDR on it, even disabled it as a test and it still didn't open).

I was able to launch the profile manager but now I am unable to as the processes launch in task manager and then within 5 seconds they close.

Firefox is not running in the background for any user (I'm the only one logged in after a reboot as well)

I'm unable to open in troubleshoot mode either. Tried run as and admin cmd "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode

Ran SFC / scannow / DISM restore health commands as well and both came back fine / no integrity violations

A couple days ago, some weird issues have started:

• All my bookmarks are gone
• Any of the buttons in the UI that open a smaller UI do not work (such as the 3 bar menu)
• Similarly, right clicking to open a menu (such as "Save Image") also does not work
• Any dropdown menus in websites seem to also not work. For example, in this very support page, I could not select an option in the "Which topic best describes your question?".

I can't restart and troubleshoot Firefox since I can't access the 3 bar menu.

How do I remove the pop up blocker on Firefox for certain websites? I am doing an online course and each introduction for each chapter has a short video that pops up but as soon as that happens Firefox sends a "Critical error" message then the video stops so I thinks that's happening because pop up blocker is turned on and I just dont know how to turn pop up blocker off for specific websites only like this one I am using for my study course. How can I turn the pop up blocker just for this one website so that this doesn't keep happening?

I don't want AI I don't even want to be near it. I don't want it lurking in the background of my browser. I don't want to waste a single processing cycle on even considering it. I never wanted AI, and they jammed it into my browser.

Currently, they popped up an ad for "AI Enhanced Tab grouping" and said that you can turn it off in the settings. I looked in the settings, and could not find such a thing. Searching for "Tabs" "Suggested" "AI" and other such related terms yields no AI things.

Why tell me I can turn something off in the settings if there is no setting to turn it off?

But that's just the start.

I want nothing to do with AI. I don't want to use a browser that supports it.

I WILL MAKE MY OWN DAMN BROWSER IF I HAVE TO. I QUIT GOOGLE, I'LL QUIT FIREFOX.

Mozilla used to be a safe-haven from all the bullshit other tech companies were pulling. And now this.

GET. AI. OUT. OF. MY. BROWSER.

I DON'T CARE IF IT'S LOCAL. I DON'T CARE IF YOU SAY IT'S SECURE. I DON'T CARE IF IT'S GETTING BETTER. I. DO. NOT. CARE.

GIVE ME THE OPTION TO PURGE AI FROM MY BROWSER OR BY FUCK I'LL FIND A NEW BROWSER.

As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you.

Since Update 147 just a half hour ago I am having trouble with pages not accepting commands. ChatGPT the Login does nothing,along with the things I have shown in attached. A few other pages that I thought was my computer playing up and did not take notice of. Any ideas and please no "dont use ChateGPT ect" I just need fixes to my problem.

A few days ago my saved passwords all disappeared. I have been logging in manually and when I do Firefox asks if I want to save the password and I click yes. The password then shows up in the saved Passwords. But... in a day or so it disappears again. What's going on? I have not changed any settings.

when I try to log into my gmail account, it is asking me to verify by log in first to an inactive account that was linked to my gmail account. with Chrome I have no problem log in to my gmail account

I am using Firefox on my MacOS Tahoe. There is a persistent annoying issue where whenever I close (physically fold) my laptop screen and reopen it, Firefox will be frozen. It will be frozen in the sense that I am unable to interact with any tabs or anything until I manually quit Firefox and reopen it (which automatically reopens all my tabs), making it usable again. This doesn't happen every time I close and reopen my Mac, but it definitely happens the majority of the time and makes the browser hard to use.

I've attached a screenshot of what a new window looks like when Firefox is frozen. It looks just like a Firefox window when unfocused.

Notes:

• It doesn't entirely freeze Firefox. In fact, I can "switch" to a different tab by clicking on the tab and then shutting and reopening my laptop again. The new tab will show on reopening but Firefox will still be frozen. This process can be repeated.
• I can pretty consistently replicate the bug by shutting my laptop, waiting 10 seconds, and reopening it. This will almost always result in the freeze.
• The bug still happens if I'm not focused on the Firefox window but on a different app.
• The bug doesn't seem to happen if I just lock my screen but don't shut it closed.

Things I've tried that haven't fixed it:

• Updating my OS.
• Restarting my laptop.
• Disabling hardware acceleration.
• Disabling themes and extensions.
• Deleting and reinstalling Firefox, including deleting the user data in the "Library/Application Support" folder.

Let me know if there's any more information I can provide or fixes I can try. Also let me know if I should go ahead and file a Firefox bug report for this. Thank you.

I'm afraid I picked up malware despite Sophos due to this message upon routine searches, e.g. "Where's the nearest pet store".
