If I want to do a 'clean' install of MS Windows - Windows 11 Pro v 22H2 (Build 22621.1485) - where are FF's sttings stored & how do I restore them after the re-install?

Firefox saves files that I only wanted to open with another application.

I checked the previous solutions in the forum, but they did not work for me. (Windows 11) I changed in system> general > download , applications > the app to open that file type and it works, but besides this Firefox keeps saving the files in the default download folder.

I tried also about:config browser.download.improvements_to_download_panel to false. browser.download.start_downloads_in_tmp_dir change to true No change - still saving copies.

Decided to switch to firefox from brave. Am completely unable to run Firefox. Doesn't even show up in task manager. I have one split second of a window, then it vanishes. Tried safe mode, tried running as admin, nothing. Brave and edge work, and I even downloaded opera to see if it would mess that up too, but opera booted fine. Running Windows 10 22H2, OS build 19045.3324. Any help is appreciated.

Hi! I have latest version of Firefox installed on my PC. But sometimes I am programming for web. So I would like to have Firefox Developer Edition as well. But I don't want them both at the same time - one for my usual web surfing and another one for web programming using leading (or even bleeding) edge features.

How do I install and use them separately? I tried running Firefox Dev Edition installer, but it does not ask questions like where to install and which Firefox profile to use.

Hi there,

i'd like to copy my Firefox profile from PC1 to a new PC2;

Last time i tried this, i ended up with PC2 having the same "name" as PC1 in "Sync". This caused weird sync issues, as the system thought my PC2 was PC1 as vice versa.

So, is it possible to copy my entire profile with all addons/settings, BUT, make "Sync" recognize it as a NEW pc ?

Thank you in advance :-)

Can I transfer my existing Firefox profile on the Windows 7 machine to a new installation on a new Win10Pro machine by copying the profile from the "AppData" location onto a pen drive, and then copying that into the comparable folder in the new machine.

I assume if I can I will then need to make the copied profile the default one using profile manager?

The bar that contained those items disappeared in Firefox after the update to 110 I believe. I don't know how to get it back, I've searched settings. The bookmarks and all the data appear to still be there. It's been there since, I think, version .9 something. I updated to windows 10 from windows 7 about 3 months back. I noticed the change immediately. I don't even know what the bar is called. I still have my windows 7 machine since I am still trying to resolve problem with windows 10 and I'm even thinking of going back to window 7. It did the update to 109 without a problem.

HELP!!

It is probably something simple by windows is more a game machine to me. I learned computers on a GE-645 to give you an idea of how old I am.

Thanks

Windows 10, Firefox will not load URLs or settings page. Uninstalled Firefox and downloaded a new copy. Upon install system error message attached appeared but browser appeared with all my bookmarks and loading error message (attached with bookmarks erased). New pages will not load.

After last update V104.0.2 fire fox will not allow me to access router to change settings message given, unable to connect, can I revert to previous version of firefox as always worked before update
