When I first opened Firefox after installing, I configured all the settings for myself. And I unchecked >Always check if Firefox is your default browser. It checked it back on by itself and now I can’t uncheck it! It’s grayed out.
I suppose that is because you have to have a default browser. Well, strictly spaking you don’t, I suppose, but some things are going to stop working.
It’s not up to Firefox to scan your system for a list of browsers to offer you, so I suppose this is the easiest way.
As someone else said, just open up the browser you want to be default and check the option there.
I want firefox to be my default browser, but I want it to stop checking if it is as I won’t install any other browsers on my system. I don’t understand why would firefox give an option to disable checking if I can’t choose. Annoying.
The check doesn’t cost you anything, why do you care? Do you think edge isn’t checking every time you start up the system or windows calls it for some reason?
They most likely do, but if there is an option to disable it, then I want to be able to disable it, even if it doesn’t matter.
I managed to change it by:
opening about:config
finding browser.shell.checkDefaultBrowser and changing to false
