Firefox Community Forum

I've been using Firefox in Windows for years as my default browser. Suddenly tonight, Microsoft Edge became my default. When I go into Windows Settings and try to change back to Firefox, Windows offers me only Microsoft browsers as alternatives (or offers to let me into the Microsoft Store): Windows Edge or Internet Explorer.

The Control Panel / Settings page "Set Default Apps" is the only way that I know that Windows lets users set default browsers, but it suddenly seems to be restricting me to only MS browsers.

Firefox works normally in every other way, but warns me now every time I launch it that I have a different default browser. When I click the button in the warning (or in Firefox's Tools / Settings) I just get put back to the Windows "Set Default Apps" page, which, again, only lets me choose Microsoft browsers.

What could have happened? I haven't altered my Firefox configuration or installed extensions or plug-ins in a long time. If I uninstall & reinnstall Firefox, will I lose my many configuration & interface settings and will I have to reinstall all my extensions -- or will the reinstalled Firefox remember its existing configuration? Or would that probably not help at all.

I'm very computer-savvy, but have run out of ideas. Can you help??

My issue is that if I access the upper right corner of the screen, titled "Open Application Menu" and go to Settings I'm told my Browser is not the default AFTER THE PROCESS OF JUST MAKING IT THE DEFAULT.

It seems there is an effort to try and drive all of us nuts. This never happened before, and if it continues it will be the end of electronic communications (which it is suspected is the plan by those who engage in violence to achieve their objectives).

What I came here for was to have my settings, after the process (done many times previously) show a response in Settings that, "Yes" my browser (Firefox) is the default, which it did for a time today. Obviously there is no persistence.

When I got help on this issue previously, my response was I already tried that, and it didn't work. There used to be a lot of different browsers. Now I haven't come across any of them currently. Some are having great success in seeing to it that only their browser will survive. That seems like a "gangland" type of mentality to me.link text I believe I spent enough of my time on this issue and explained it in detail. There's really nothing else I can "contribute".

I, by the way, went to my Internet provider today who found an email under Preferences that she said had the capability to steel my emails. It had an extension in Australia (*.AU). If that has anything to do with this problem I'd like to buy a pair of handcuffs to see if that individual(s) being constrained from using a PC keyboard is a cure for this problem.

I have firefox set as the default browser on my PC : windows 10, dell pc. but edge often comes up when I click on a link in an email or website [even searched in firefox] how do I turnoff Edge's override?

hello, how to display only the preferences that I have personally modified, without those that an external program has modified: there are too many of them, and this button loses much of its usefulness.

I tried to do this: [quote]Locate and delete the file prefs.js (or rename it, for example, to prefs.jsOLD, to keep the old file as a backup). If you find more than one, a prefs.js.moztmp file or a user.js file,

delete (or rename) these as well. (/quote]

but it doesn't work because there are still “modified preferences” coming from who knows where.

Is there a setting that prevents Firefox from closing immediately when the X in the upper right corner is clicked? Thinking a question "Are you sure that you want to close Firefox" should pop up. Recently I've closed Firefox accidentally and lost all of my open tabs (I don't keep history).

I run Linux Debian 12 (bookworm), and there seems to be no way to disable Firefox from automatically starting up after system boot. I've searched through settings, read countless articles on the internet, looked at system auto-startup applications, but wasn't able to find anything that worked. I even looked in about:config, but couldn't find anything. Firefox isn't automatically started by my system and there is no parameter that disables it. I also didn't click through any choices about autostart when I first opened Firefox.

I'm on v137 on Windows 10.

I cannot play my Unifi camera videos because they require HEVC. I thought v134 and higher had HEVC support?

There were some mentions of needing to get the HEVC codec from the Windows Store, but I could also not locate that from Microsoft either.

Under about:support, it says HEVC is Unsupported. What am I missing?

I was advised by Sainsburys to change my default browser to Chrome due to a problem with their website. that did not solve the problem and I now can't restore firefox . Have I been blocked from firefox for moving away if not please help me return to firefox.?

Hello

Thank you gregor neusch
