Firefox Community Forum

After having upgraded my W11 system to 25H2, I cannot install any extension. Installation terminates with "... something may be broken. I'm using FF 144.0,2. FF is used an more than one account alternatively.

An a second system, with less security measures I have no problems.

Hello, I reset my PC yesterday.

I didn't know my Firefox password anymore and clicked "Forgot password."

Then I created a new one.

Now my saved online pages and everything else are gone. So synchronization isn't working.

I have an account recovery key.

Will that work? And how?

Please help me.

Regards, Daniel

Hi, after latest update just now, the browsers uses up to 45gb of ram within a few minutes! Not sure what it is, I am on MACOS Sequia Version 15.6.1 (24G90) macbook pro M1

Firefox updated to the latest version and it lost everything. All my saved passwords are gone, all my bookmarks, data, etc. It said I could sign in with my account and it would sync them and bring them all over, it didn't. I can't use the original profile because it says it's outdated, I don't even know if it's the correct profile anyway. What am I supposed to do?

When i open firefox, i can choose what profile to open. I have two screens, so i was wondering if it was possible to be able to open both profiles i use, and have one on each screen. If not possible, would it be considered for an update in the future? It would make it easier, so i can have my personal profile on one screen, and my work profile on the other.

THE ABOVE ERROR MESSAGE HAS PREVENTED ME FROM ACCESSING 3 WEBSITES - PaddyPower, Ladbrokes, & UK National Lottery. None of the suggested remedies has had any effect. Can you fix it?

Hi everyone, I run a website, which provides information about mobile phone prices and SIM packages in Bangladesh. I’ve been working on improving page load speed using LiteSpeed Cache and Cloudflare CDN. While it works well in Chrome, I’ve noticed that Firefox doesn’t always cache pages or static assets (like images and CSS) as effectively. Does Firefox handle cache-control headers or service workers differently than other browsers? I’d also love any advice on best practices for implementing browser caching or service worker scripts that improve performance on Firefox without causing outdated content issues. Thanks for your time and any insights!

I have your current fire fox...Each time I try to access my bank...I get a message to upgrade my browser...FIREFOX wont let me upgrade, and I cant get into my bank..

I need a way to keep firefox and still access my bank info...I have tried other browsers but they wont work since I have windows 7..

Is there anyway to keep my current firefox browser and still be able to get into my bank.

THIS is very inconvenient for me...I have enjoyed using your browser but this causes me alot of hardship.

THank you for any help

whenever I do a Firefox update, there sometimes is a new extension included that I personally feel no use or need for..most of the time I can disable them w/programs like Ccleaner (see image), but some are persistent, and return the next time I open Firefox. Firefox always consumed a significant portion of my 8gigs of RAM, and my latest update to 144.02, it is approaching 15%. Any way I can stop this short of reverting back to previous version?

My question is above!

I had a free chatGPT on firefox sidebar. you changed it to Anthropic Claude without my permission. Now I have to pay for something I was getting free as a student of a university.

How can I restore the FREE ITEM AND GET RID OF SOMETHING I WILL HAVE TO PAY FOR...AND STILL USE ai?

For the last couple of weeks my default search engine keeps changing. Even though I change it in the setting to the one prefer eventually it changes. Why is this issue happening and is there anyway to force my preferred search engine as a constant default?

Went to bed last night & firefox was fine.

Opened it this morning & I don't see my bookmarks. The folders on the toolbar from Africa to Healthcare all say empty. Lottery thru web cameras have links in them that I can see. I I open another tab & go to google, then save that bookmark in the google folder it won't let me yet edit bookmark shows.

If I click edit bookmark it tells me that it's in the google folder already yet when I click on the folder, it says empty..

Ran a virus scan. It was clean. I tried restoring bookmarks from a previous day. Firefox was unable to do it.

What is going on? If the bookmarks are there, why can't I see them?

I've used this browser for years without a problem. Now all the sudden it's one problem after another. I'm ready to jump ship to a different browser.

I'm on version 144.0.2 (64-bit) using Windows 11 Pro.

Launched this morning and the interface is totally different. That's not the problem All my bookmarks are gone and I'm unable to restore them

Can I move back to the previous version of FF?
