Firefox Community Forum

Hello everyone, I run into a problem setting up my new mini PC, Geekom A6. I downloaded Firefox as usual from https://www.firefox.com/de/. I started the installation, and everything went through perfectly fine. When I expected that Firefox would start, only the Profile Manager started. When I try to create a new profile, the wizard appears for a millisecond and closes instantly. Here's the whole start process as a video: https://streamable.com/zkeb46 https://streamable.com/zkeb46

What I already tried to fix it:

• Run Firefox as Admin -> nothing changed
• Rename profiles ini -> nothing changed; ini was not newly created.
• Manually create the Profiles folder. That actually let me start the wizard but would end in this failure message:

"Profile couldn’t be created. Probably the chosen folder isn’t writable. [Exception... "Component returned failure code: 0x80520015 (NS_ERROR_FILE_ACCESS_DENIED) [nsIToolkitProfileService.createProfile]" nsresult: "0x80520015 (NS_ERROR_FILE_ACCESS_DENIED)" location: "JS frame :: chrome://mozapps/content/profile/createProfileWizard.js :: onFinish :: line 250" data: no]" I gave this folder every access right for everyone, but still the same error. I tried to choose a custom folder, which worked (once in Document and once in C:/Firefox/Profile). But when I wanted to start Firefox, this error came: "An unexpected error has prevented your changes from being saved." and the option to restart Firefox. When I do so, I am once again back at the Firefox profile selection (but the previously created profile is not visible to select).

• Use an older installer of Firefox -> I tried 1.40, 1.39, and 1.38, but the same problem everywhere.
• Using winget but that led to the same error.
• Starting firefox in save mode (firefox -safe-mode) also leads to Profile Manager

I am using the latest Windows 11 24H2 and drivers are up to date.

I hope you can help me using Firefox on this device.

Upon installing Firefox, it appears to run fine. However, upon closing and attempting to reopen Firefox, a small window showing "Run Firefox in Troubleshoot Mode?" will appear briefly, then close. I have already tried running it as administrator, and reinstalling several times, to no avail.

Application error: a client-side exception has occurred while loading (see the browser console for more information).

where is the browser console? how do i fix it never had an issue with until the last two days?

Fix it. Tnx, Larry Yesterday I got a full page notice that told me my access to Firefox will be shut down because my Defender detected that I had stepped in some SHXT while visiting something in Firefox. They gave me a phone number of Microsoft something to call to fix it. I did not call because it seemed like malware, I guess it wasn't because soon after Firefox would not load. I will get this when I try: Says: cannot find server v3lpea6ndyxwl4.azureedge.net , I have run Malwarebytes and Defender and rebooted. Any ideas?

I'm having major problems with Firefox and was able to use it for a long time and I love the software to death. But it has given this problem that I have run into before which the only way I was able to fix it was a full wipe of my computer to factory settings. So with this I started to troubleshoot on what I could do and reinstall was the first and send commands to refresh the dns but I found to what seems to be a startup incomplete file in the Firefox software and it seems to create itself even when deleted. It could be this which is causing problems but all I know for certain that when I click on Firefox it won't open at all or startup. With the only evidence that it responded from task manager or a popup talking about wanting to refresh Firefox for 0.1 milliseconds
