I want to turn on my Firefox vpn in my iPhone but when I tap my Firefox icon, I get get the google browser instead of Firefox browser and there is no icon to turn on vpn in the google browser page.

Anyone succeed with running Firefox in headless mode under Ubuntu?

I tried:

firefox --headless --safe-mode -P headless https://quan.hoabinh.vn

but got this error:

[12545] Sandbox: CanCreateUserNamespace() unshare(CLONE_NEWPID): EPERM

• • • You are running in headless mode.

[GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt

I installed Firefox as from "https://packages.mozilla.org/apt" repo.

PLEASE HELP! One day last week, Firefox for my PC disappeared and it seems that Duckduckgo has taken over. I have used Firefox on my PC for a few years and occasionally use duckduckgo as my browser. Now I cannot find Firefox. It is up-to-date, as of last week.

Please Help RhonCa

It is as if Firefox has disappeared from my desktop. I click on the shortcut but nothing happens. It was working fine last night. I have tried uninstalling/reinstalling but still nothing. A window does not even appear.

I am not able to open my Firefox browser tonight. It was work yesterday. WHen I tried to refresh it the wheel kept spinning for over 15 min and there was no sign that it would complete the process.

After the last update, Firefox won't open. Instead, I get this message:

"Firefox is already running but is not responding. The old Firefox process must be closed to open a new window."

I have closed it within the error message but the error message comes back each time I try to open Firefox.

Please help, Deb

This morning I reset my PC, and upon doing so Firefox would just not work. Anytime I tried booting up firefox it would for a split second show the browser than revert to a screen where its just the firefox logo, where upon clicking it would become unresponsive

I've uninstalled and reinstalled twice both times completely clearing out firefox data from across my pc, i've tried to make new profiles, i've cleared out caches etc, yet anytime i try boot it up it still doesnt work

i've spent the past 6 hours just looking through fixes and still, nothing works every other browser works fine, aside from firefox

Can you help me repair my FireFox Browser? The shortcut did not launch the browser. It stated that the file had moved or was no longer working. It still appears in my App folder but the only option is to uninstall it. I have a great deal of short cut tabs and all my stored passwords. How do I repair this? If I re-download Firefox will it access all of my stored information and preferences?

Hello and I hope you are doing good,

Sadly for me it is absolutely not the case It has been a few days since I can't use Firefox at all. When I try to open it, it tells that there is a "side by side error" and that I should use sxstrace.exe. I did that and it tells me that It can't find mozglue, mozglue.MANIFEST, mozglue.DLL. I use Mozilla in French (it is my mother tongue), and it can't find them in French, English or in Neutral :

Thinking it was also linked to the Redistribuables Microsoft Visual C++, I just downloaded all of them again.

My version of Mozilla is 152.0.6.595 and I am on Windows 10.

Please I really need your help and don't want to lose any of my tabs, bookmarks and passwords as I was making very important research for my PHD studies.

Real thanks in advance for your help.

I don't use Firefox daily, so not sure exactly when it last opened ok on my iMac (26.5.2). So I downloaded Version=153.0.1 BuildID=20260727124451, and tried again. When attempting to launch, the icon in the dock bounced a few times, then nothing. When repeated, it only bounces once.

Likely unrelated, but I had very recently upgraded my LuLu app (4.4.3) from Objective-See. It monitors outbound connections. But disabling the app changes nothing.

I'm not a MacOS guru. I expect there is an error in a log file somewhere that reveals the problem, but I don't know where to look.

Suggestions?
