Firefox Support Forum

Howdy,

Workflow: I have a firefox instance already running. I want to launch a new firefox in safe-mode to test something without disrupting my existing firefox.

Problem: I try to launch a new firefox in safe mode using `firefox --safe-mode`, but firefox just opens a new window NOT in safe mode.

I think it may because firefox in safe-mode requires launching launching from a new instance rather than attaching to existing instance.

`firefox --help` shows a flag I can use:

--new-instance Open new instance, not a new window in running instance. --safe-mode Disables extensions and themes for this session.

So I run `firefox --safe-mode --new-instance`

now I get error popup with message:

"Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."

Now I think what is the point of the flag "new-instance" if Firefox doesn't support multiple instances?

Regardless, how can I launch firefox in safe-mode without disrupting my existing firefox instance and without relying on creating a profile just for this?

I cannot open any Games on the NY TImes site with FIrefox for the past month; no problem with Chrome. Today, two article links opened but then the page went blank (repeatedly), while other links worked fine. Again, no problem with Chrome. My wife can't get into proxyvote.com with Firefox--again, a blank screen. Where is this weirdness coming from?

Hello! I have some proplem to update Firefox on all my six computers. It is also impossible to download a new Firefoxand install on a clean computer . The message I get is as the image below. Regards/Sture Axelsson sobaxe@gmail.com

I'm encountering an issue with accessing my website, www.mobilepackages.in. When I try to access it using the HTTP protocol (http://), the website doesn't appear. However, when I use the HTTPS protocol (https://), the website shows up without any problems. What could be causing this discrepancy? Any insights or troubleshooting steps would be greatly appreciated!

My default search engine is Duck Duck Go. I frequently use a VPN.

I am usually in North America and want to search sites in North America. When I run a search by typing a search term in Firefox, I get results beginning in UK, and I see that a blue toggle switch has been set to UK. (See image.)

This started 2-3 weeks ago.

How do I set things so that my searches begin in North America?

I have checked "about:config" preferences and do not see anywhere that UK is specified. I don't see a region preference setting, either.

Thank you.

Hi Friends.... This morning logged into my website as usual and this message appeared on the home page. I have not checked the link as it seems potentially malicious ... It does not appear when visiting my site on Safari. I have emptied the cache I have been through troupbleshooting mode I have reinstalled Firefox and it still is there..

How to rid myself of this

All help gratefully received Graham

Macbook pro 2017 OS 12.7 Firefox 125.03

when I entered this string - chrome://pippki/content/exceptionDialog.xul - I got a 'file not found' message. Is there another way to access that? I am trying to get to https//mlb.tickets.com and get this message: The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

I keep needing to sign back into my main (default) Google account when I restart Firefox. Checked cookies and even disabled blocking of any cookies. Still same issue, and unique to Google. All other sites (Facebook, LinkedIn) stay signed in upon browser restart.

Ever since the latest update, the picture-in-picture function stopped working properly. If I activate it, the video will automatically go to full screen, and I need to press the full screen button multiple times to move it down to a small box. I am using Firefox on a Mac laptop.

Hi,

I have Windows OS and use Firefox as my main browser. Firefox settings are set for dark mode and it works in google.com etc, but when I open iCloud Notes, it's full white and not in dark mode. Can someone advise how to change iCloud Notes also to dark mode? I have cleared cache etc, not helping.

Firefox can’t establish a connection to the server at wss://centralindia.stt.speech.microsoft.com/speech/recognition/interactive/cognitiveservices/v1?language=en

So for some reason I have two versions of Firefox on my computer (Windows 64 bit), I am logged in and using one of them, and the other is just there. I could log in there but I don't want to, I just want to get rid of it. Links from Telegram open in it, creating a second Firefox window instead of opening in another tab in the already open Firefox window, which is very inconvenient. The windows list of programs which can be uninstalled only has one Firefox (I've tried deleting and reinstalling, it doesn't help). But when I try to choose a default browser I get 2 icons to choose from which look the same (see screenshot). What the heck? How do I manage this!

Just transferred from old MacBook Pro to new one. Successful migration except: The icon for the WE Transfer service doesn't show up in the narrow black ribbon at the top of the Firefox page - instead there's a blue exclamation point in a blue circle. Clicking the blue circle/exclamation point takes me to the WE Transfer page. What do I need to do to get the actual icon to replace the blue circle/exclamation point? Thanks in advance.
