Windows 10: Can Not Set Firefox as Default Browser

I've been able to set Firefox as my default browser before, but recently after reinstalling FireFox, Wi10 is simply not allowing me to set a default browser at all (other than default - Edge).

Can't set Firefox as Default Browser

I can't seem to set Firefox as my Default Browser, for some reason. It's really getting on my nerves. I've just done a clean install of Firefox to see if that solves it, but nope. Any suggestions?

I'm on Windows 10 with the latest update. It's unactivated at the moment, I'm going to buy a key as soon as I can, not that it should make a difference. My PC is an i5 powered desktop with a GTX770 overclocked and 8GB RAM, if it makes a difference.

Thanks in advance

 

My Win7 that Upgraded to Win10 retained most of the default programs settings including Firefox. I checked my Win10 Insider Preview and using Control Panel, Default Programs successfully set Firefox as the default.

 

You can try the link below. It was the same problem as yours.

Thanks guys. TopGun's method worked, however if you're control panel is set to Categories, you'll want to change the View By to large/small so you can more easily find the Default Programs selection.

 

Hi from Win 8 on, programs (not just FF) are not allowed to set defaults from within the program. Unfortunately, mostly (VLC player being one exception) you don't get any warning. Defaults have to be set outside the program -
- from Settings
- from the Control Panel
- using Open With.

Note too that you may wish to check the association of HTTP and HTTPS in the Control Panel, Default Programs, Associate a File Type.. is set correctly. I've found previously this needs to be set manually for embedded URLs.

 

Since you have the answer and your problem is solved, please mark it as Solved so that others with the same question will know there is an answer here.
Thank you.

 

Hi,

Thanks to everyone involved.

I found a new twist to this, I think I did anyway.

I had the same problem but I was trying to set Firefox as my default browser on a second Microsoft login on this PC. I mean a guest login, not the administrator's.

So I couldn't open the Control Panel and if I ran Firefox as administrator it just logged me into my main Firefox account on my main, ie administrator's, login. (Which I set as default there without any problems earlier).

In my case Firefox didn't even appear in the default browser settings options list. It was just not there although other non Edge browser options were, eg. Chrome.

Turned out that under 'Settings - Apps - Default Apps' there's a clickable 'set defaults by app' option. It was easy to choose Firefox once that had loaded.

Hope I haven't just repeated something someone else said earlier in the sister thread about this and that this is helpful to someone.

Cheers.
