FireFox quit working and would not even launch. I had to uninstall and do a new installation. Firefox works but I cannot make FireFox the default browser. I have looked thru all of the Support topics and none are helpful. What I need is simple instructions to fix the problem. I am running Windows 10 Home. When I launch FireFox, the program asks to make FireFox the Default Browser. I click on the Make Default and it opens Default Apps, I click on Web Browser and there is no FireFox.

What do I have to do to make this work like its supposed to? I have attached a file with screen capture of which browsers I can choose. FireFox is not there.

Chosen solution

There is a command line switch "-setDefaultBrowser" that you could try.

Hi, please do a uninstall and reinstall this way : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files , C:\Program Files(x86) & C:\ProgramData Then restart system. Then run Windows Disk Cleanup. (Note: This should be Pinned and run Weekly, If never done below expect 10's of gig's) Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do :

Reinstall with Current Release Firefox 61.0.2 with a Full Version Installer

Please let us know if this solved your issue or if need further assistance.

Well there went an hour of my life with no results.

As I said before, I followed all instructions in the topics and nothing works. And followed your instructions to the 'T' and nothing. Still cant set FireFox to default browser.

Please give me useful help and fix this.

Finally, why was this so hard? Further investigation showed Microsoft pushed an update and this is when FireFox quit working. You would think Mozilla would be on top of that.

Its fully working now.

I have the same problem. I have reinstalled Firefox 62.0 on a new Win10 Home 64 bit computer. Windows does not recognise Firefox as a browser option. I looked at ttps://developer.mozilla.org/en-US/Command_Line_Options but this is a guidance note, which gives no information on how, where or when to apply the switch as the default mode for all actions on the computer. I imagine that MS is deliberately making it difficult to use Firefox. If so, they are succeeding.
