Hello,

I am having an issue with my Bluetooth headphones (Sennheiser HD 450BT) in Firefox on Windows 11.

The headphones are properly connected to Windows and work correctly with other browsers (Edge, Chrome).

Windows shows the headphones as the default output device (stereo), and test sounds play through them.

However, in Firefox, the audio does not go through the headphones. Instead, it plays very loudly through the laptop speakers.

The problem started today; there were no issues for about a year.

I have tried reconnecting/reinstalling the headphones, but it did not help. Drivers are also up to date.

Could you please advise how to make Firefox correctly use my Bluetooth headphones as the audio output device?

Thank you for your assistance.

Hi Team , I am using my firefox browser profile logged in with "[edited from public] @tothenew.com" . Today when i open browser and got to know my account has been logged out while trying to sign in again to my profile it required to get authentication code sent on mail id but i had lost that mail id . so could you please help me to gain acces to that profile i have bookmark some important document on this .

Reader view doesn't work on many Lifehacker pages/articles. Can something be done to make it work on those pages? Here's an example:

While I'm using Firefox, I try to go to a new website and Firefox says that it's installing a new version and I need to stop what I'm doing and restart. When Firefox restarts, it forces me to create a new profile and I've lost everything I had before.

This happens two or three times a day.

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

Hi -- I'm getting quite a few page crashes that seem mostly tied to YouTube, although not exclusively. I only recently swapped over to Firefox from Chrome because I was having similar crashing issues with that browser as well. This is after a fresh install of Windows 11 Pro and a number of different benchmark tests (no known issues with CPU, GPU, or RAM).

Since there are so many reports that all seem different, could someone help troubleshoot? I really can't tell if it's a browser problem, maybe something with my MOBO or PSU or other hardware.

I'm having trouble opening urls in a private window from the command line on Windows 11.

Firefox version: 144.0.2

Starting a new private window works fine with "C:\Program Files\Mozilla Firefox\firefox.exe" -private-window

But doing: "C:\Program Files\Mozilla Firefox\firefox.exe" -private-window "https://www.google.com"

just opens the link in the last selected window if the last window selected is non private it just opens the link there instead of a new or existing private window

I have also tried with no success: "C:\Program Files\Mozilla Firefox\firefox.exe" -private "https://www.google.com"

Hello!

I use a VPN when I access the web and I recently updated my OS (Mac OS Tahoe). I updated Firefox and now DNS over HTTPS (DoH) is enabled in Firefox. When I have my VPN enabled, I cannot access the web, there is some problem with DNS resolution. I have changed my Firefox DoH settings to Standard (I have also used Strict) and have typically been unable to resolve web URLs correctly. There have been a few times that I have been able to use 'Standard' DoH strictness / settings and also use the VPN successfully at the same time, but typically when I have the VPN enabled Firefox cannot access whichever 'mozilla.cloudflare' address it is attempting to use for DNS resolution.

The VPN vendor suggested always using the VPN's DNS resolver. I have done this and I still have the same problem. What should I do to ensure that I have secure DNS and can successfully use a VPN?

Thank you.

When I want to duplicate a tab, can I configure the 'duplicated' tab so it appears exactly next to the tab I'm duplicating instead of at the end of all the open tabs at the far right end of my browser? If I can't would it be too much of a bother to include that as an option we can configure? Maybe it's ridiculous or I'm using the interface wrong but it's super annoying to have to manually grab the duplicated tab and scoot it back next to the tab you duplicated from. Thanks!

I have recently encountered reproducible failures when attempting to download files or save pages to local storage. The target directory is located on a mounted NTFS file system with the options umask=007, user=root, and group=disk. My Firefox browser is running under a non-root user account that is a member of the disk group. However, I consistently receive the error message: “XXX could not be saved because the source file could not be read.”

I would greatly appreciate anyone's assistance in resolving this issue.

Today is 11-12-2025. After the last update a few days ago, many of my websites would not load up on firefox and when try on Edge or Chrome, they would work perfectly. I did a recovery back to 10-31-2025 and everything worked fine. Now I am afraid to do another update until I know what is going on. What would you suggest? Thanks,

Hello there, today was released a new version of firefox. downloading it not only crashed my computer, it also removed all my history and bookmarks. is there any way to revert this?
