I'm running Firefox 144.0.2 (64-bit) on a Mac using Sequoia 15.4.1 OS.

At the most recent Firefox update, I added VPN.

Since then, I've had a problem with Firefox hanging. Not immediately but after varying amounts of time, 20-60 minutes. I get an "Out of Application Memory" pop-up but the usage for both Firefox and other elements are well within normal range, not high. It's completely frozen and the only way out is to do a Force Quit.

There are times when doing a shut down I notice that VPN has somehow been turned Off and once I saw a message of Background Service Error attached to it.

Having to constantly re-start Firefox is a major pain. Oh-- I did turn off the background AI thing under Tabs. I hate AI and try to turn it off everywhere I find it. A resource suck and bad for the planet.

Any help appreciated.

I have no idea how my bookmarks disappeared, but I cannot locate any of them. How can I get, at least, my bookmarks from one month ago. Have an upgraded computer, new hard drives, etc. I've searched my computer, cannot find any bookmarks. Is there hope? Win `11

I installed Firefox yesterday, and everything was fine for a day. Today, when I play a YouTube video, the entire page freezes - I can't pause it, select text, or do anything. The page starts responding after about 10 seconds from last interaction.

Compared to Chrome, I can play 20 YouTube videos at once and everything works fine.

The problem only occurs on YouTube. Sites like CDA and Jellyfin work fine.

I've blocked access to nearby devices without knowing that this would affect my local network websites. Now the option to change this on the settings simply does not appear for me. What can I do?

Speech output for Albanian on the website "loecsen.com" > language course "Albanian". Words cannot be heard under Windows 11. What can I do? I downloaded the Albanian language pack, but the voice isn't there. Is this a Firefox or Windows problem?

Greetings from Switzerland

I am a pensioner in te UK. Due to restricted mobility I spend a lot of time using Firefox to access many web sites. This normally works perfectly. Today I tried to access the web site of national chain store specialising in outdoor clothing and equipment because I need a new showerproof jacket. I have never used that site before, yet Firefox reported Error 403 : Forbidden. Have you people never been told tat error messages are supposed to be useful? What is Forbidden. Why when it has not happemed before?

The web site is https://www.millets.co.uk/

I have a web site so I have other browsers just for checking for layout problems.

I tried Chromium, same error but the message said You are not authorised to access this site. Presumably that is what your incompetent message should have said. But why should a pensioner trying to buy something from a chain store ever need any sort of authorisation?

I tried Opera. Connected me no problem!

I tried Edge. Connected me no problem.

Clearly somebody somewhere is an incompetent idiot, but it isn't me. So who is it? If it is yourselves then please do something to fix this.

Hello, I reinstalled Firefox and am unable to recover my bookmarks and other data. Before the re-installation, I manually backed up my data, but when I try to restore from the backup, it does not work. All my bookmarks and previous data are still missing. How can I fix this and recover my information?

Hi,

I am using mTLS to authenticate my computers reaching websites I manage. I imported client certificate on firefox and cloudflare is checking if the client is sending the right certificate. I am using Debian and Windows. On Debian (13), everything was working great until the version 140 ESR. I don't know why but the client certificate is not sent to cloudflare, sometime it is (when CTRL+F5) but no CSS is rendered. So I can't reach my websites. Firefox is still asking for the right certificate to send but that's all. This is weird because on the same version on Windows, with the same certificate, it is working. I tried newer version (144.0.2) on Debian but it is not working. The version I use at the moment is 128.14.0esr. Cloudflare is blocking the traffic because no certificate is sent. If I disable the rule, it is working.

Could someone help me? Feel free to ask for more details.

When I click on KPN TV+ I see a message: Firefox is installing missing components, try later. But Firefox is NOT providing missing components.. Or is the problem that KPN (and Ziggo IPTV) can NOT run on Linux???

On my other Laptop I experience weird behavior since 1st of October. Only on FF Desktop I couldn´t zoom on Google Maps. The mousepad gesture moving your fingers apart and closer together to zoom in and out only increased the zoom of the page with the searchfield, all the buttons and so on. I could repeat the behavior with FF Nightly. On other browsers it worked.

When trying to report it, I was send into an endless loop while trying to post a question.

MacBook Pro M4, OS v 26.0.1 Firefox runs fine as administrator. There is an issue with standard users. I have completely uninstalled and reinstalled Firefox multiple times from the Firefox webpage. When I try to run Firefox as a standard user a screen pops up. Firefox is trying to install a new helper tool - enter admin name and password. After I enter the user name and password the pop up screen disappears. If I click on the Firefox icon the same pop up screen appears again. I can select cancel, however, when I go to the Firefox icon it is bouncing up and down for several minutes. If I click on the Firefox icon again after it stops bouncing the process repeats itself.

One last thing Firefox was running fine until the latest update on 11/02/2025.

How can I resolve this issue?
