Firefox Community Forum

We are experiencing an ongoing issue with Firefox that persists even after performing the following troubleshooting steps: - Uninstalled Firefox completely. - Removed all browser add-ons and extensions. - Reinstalled the latest version of Firefox. Despite these steps, the issue still occurs: Browser crashes, pages not loading, extension not working. Additional Information: - Operating System: Windows 11 Pro - Firefox Version: 145.0.1 - Error Message:

We would appreciate guidance on resolving this problem, as standard troubleshooting has not resolved it.

Thank you in advance for your assistance. Kind regards, Edward

The previous version allowed me to have Firefox as my browser and Brave as my search engine. Now Brave is both my browser and search engine. In the general settings, it says Firefox is my default browser. I'm confused. I just want to be like it was before the update. Please help.

Is there a way to completely opt out of having AI in my browser?

I find recent implementations of AI in Firefox quite frankly disgusting. I don't want to see it, I don't want to use it, I don't want it suggested to me. Not only it's unneeded, but also all your LLMs are a waste of electricity, fresh water and are a threat to my privacy, and we don't even mention all the legal trouble AI scraping creates.

I need a switch to completely remove any mention of LLMs/AIs in my Firefox browser unless I search for it on the internet (and, trust me, I wont; I'd prefer to continue thinking for myself and having real people with skills and talents do things if I can't do them myself) and have none of them touch me in any way. Kill that thing with fire.

Ideally Firefox, one that advertises itself as a secure browser with respect towards its users, shouldn't have any mention of AI in the first place, you know. But since companies are in a craze about it for some unknown reason (trust me, we don't want it; if I want to be lied to, I'd go to a paediatrician to talk about my symptoms, not a language model I can't trust with my data), at least give your users an option to get that awful thing out of their browser it they want to.

Have a nice day. <3

When following the instruction to sync bookmarks on Android phone it leads me to items that are not there. Open Firefox mobile on phone. Ok. Hit the 3 dots drop down. Ok. Choose sync and save. Not there? I click my email and it shows sync. I click that and it shows the last time I sync my phone. 0 minutes. Ok. It shows a QR code to scan from the Firefox app. It instructs to click ready to scan. That's not there either. If instructions lead you down paths that are not present, the instructions are useless. Anyone else having this experience? Thanks..........

When pasting an image from the clipboard in Outlook Web Access in Edge there's right mouse button option to "Paste as Image". This places the image inline. In Firefox there's no option like this.

Safe mode (troubleshooting mode) doesn't fix this. Ctrl + V or Shift + Ctrl + V doesn't fix it. Shift RMB to get Firefox menu does show Paste and Paste without formatting but it doesn't paste any inline image.

I've attached a screenshot of Edge and Firefox with the Outlook context menu and Firefox context menu.

Firefox version: 140.0.4 (64-bit) Edge version: 138.0.3351.83 (Official build) (64-bit)

I was asked to create a new profile in order to keep using Firefox, despite never having an account. After I clicked okay, it opened the new version of Firefox, but without all the passwords, bookmarks and history of the past few years. This is really inconvenient. I have since then made an account, but the fact that I can't find any of this data anywhere has me worried that every time I update Firefox it will wipe my account.

I have Firefox installed on three Windows Desktop Computers. On one, I just cannot delete Bookmarks, no matter what suggestions I try. Verify Integrity of the database produced no results. I do not, for a variety of reasons, sync bookmarks (or anything else) between the three installations. Experienced user that has spent far too long on what should be a simple issue.

At your recommendation I signed up to Ad Avoid and now FireFox tells me that I could/should not access BT.Com because of the certificate issued by Ad Avoid

I did some research recently on some travel sites.

Today, while trying to research which tab was doing DNS queries to SnapChat (which I never use) I learned about `about:processes`. I found 5 "hidden" tabs from various travel sites (some of which I never visited) running in the background. I did not explicitly hide any tabs.

WHY IS IT ALLOWED FOR SITES TO KEEP OPEN HIDDEN TABS AT ALL WITHOUT TELLING ME ABOUT IT?

This is not conducive to trusting Mozilla.

Firefox kept eating my RAM, running dozens of processes. I have gone into about:config and set the dom.ipc.processCount to 1 - then I restarted Firefox and found 5 processes running straightaway before even using the browser. I closed it down and have started it again and now there are 11 processes running with just one tab open. Firefox(9044) Utility(7552) JavaScript oracle Network (15912) Data Decoder (11364) GPU (18744) About pages (12536) Preloaded new tab Extensions (20544) Preallocated (16132) Preallocated (13780) Preallocated (16044)

The problem repeats on three different computers which are not infected with malware. One computer with slightly less RAM I now cant even use Firefox at all (though all other browsers work fine) because the tabs constantly crash due to the high number of processes. Is there any way to set the process limit low in a way that Firefox actually responds to?

I GOT TIRED OF FREQUENT FIREFOX CRASHES (C0000005) IN BOTH THE 64-BIT AND 32-BIT DESKTOP VERSIONS. I HAVE BEEN USING THE 64-BIT VERSION IN WINDOWS 11 (I HAVE A HIGH-END SAGER LAPTOP WITH 32GB RAM. I INSTALLED THE FREQUENT FIREFOX UPDATES BUT THE PROBLEN PERSISTED EVER SINCE VERSIONS 42X WERE RELEASED. I TRIED THE 32-BIT VERSION BUT THE PROBLEM PERSISTED. FINALLED, I TRIED THE DEVELOPER VERSION: NO MORE CRASHES! I READ THE RESPONSES FROM YOUR CLUELESS STAFF TO OTHER CUSTOMERS WITH THE SAME TROUBLE. THIS IS NOT A WINDOWS ERROR; THIS IS A FIREFOX APPLICATION ERROR. MAYBE SOME OF YOUR FIREFOX DEVELOPER CODERS SHOULD ASSIST THE 32-BIT AND 64-BIT DEVELOPERS. OR, DUMP THE VERSION 4X CODE AND BUILD ON THE MORE STABLE 39X CODE. ALSO, DON'T BLAME WINDOWS FOR FIREFOX APPLICATION ERRORS. AND...NEVER SUGGEST A WINDOWS REINSTALL FOR FIREFOX ERRORS!!!

Good evening,

When the translator starts translating from English to French, it displays Indonesian, but I haven't installed anything in Indonesian, and I don't read Indonesian, so where is it coming from?

I'm hacked ?

If I have taken photos in past years on a particular date, I get an email from Microsoft to review them. I normally do it on my phone, but today tried it from my computer. The path is "One Drive" "Photos" "Moments" and then "On This Day." If you click on the photos that in the graphic that looks like a movie strip, a montage of the photos shows up and you can also click on one. However, in Firefox, I click on a picture and the screen goes gray, but nothing ever loads. I thought it was a Microsoft issue so used their help function. The rep and I tried it, then cleared the cache, then tried it in a private setting. We got the same result every time. Then he tried it whatever Microsoft's browser is called and it worked just fine. They said it was a problem on the Mozilla Firefox end, so I'm reporting it. Please let me know if you can help me make it work. I don't like using anything except Firefox.

I am so tired of the stupid banner popping up every time I put something into full screen, that says "press escape to exit full screen".

Is there a way to disable that?

I am on a windows 10 PC.

mozilla won't save my previous windows and tabs even though i have that check marked in the settings. it's been like this for months. to keep them i've had to keep my pc on for moths. help, i'm thinking of leaving Mozilla because of this, it's incredibly frustrating to lose all my work every time.

Hello,

I'm facing an issue where my microphone does not work in Google Meet when using Firefox, even though I’ve granted all necessary permissions. This problem is specific to Firefox, as the microphone works perfectly fine in Google Chrome.

I prefer using Firefox because of its convenient screenshot features, but this microphone issue has caused major inconvenience during important meetings.

Kindly help me resolve this issue.

Thank you.

I have been trying to enable Firefox Sync on my Windows 11 PC (Firefox 145.02). I open the Firefox Sync window, I click on Log In, I enter my e-mail and click on "Sign up or Sign In" and then the view freezes and I never get any further. The attached screen capture never changes, no matter how long I wait.

Hello,

I’m experiencing an issue where I cannot use ChatGPT-5 in Firefox. When I log in and try to select or use GPT-5, nothing loads or functions properly. Other models like GPT-3.5 work normally, but GPT-5 does not respond.

I’ve already tried refreshing the page, clearing cache and cookies, and even disabling extensions — but the problem persists. Could this be a compatibility issue with Firefox? Any advice or support would be appreciated.

Thank you in advance for your help!
