a problem with firefox been the default browser

No I don't remember seeing it before installing Waterfox. Also, I tried uninstalling both Firefox and Waterfox and then installed Firefox, still not present on the Default Browser list.

Windows 10 1809 with the latest updates but the same problem was there in 1803. I didn't notice it before then.

I tried the suggestions in the link you provided and nothing worked except the last one with the command prompt command. That worked on the laptop that was most affected and made Firefox appear on the list and is now my default browser.

I also have a desktop which has had Firefox as the default browser forever but it doesn't show up on the Default Browser list and none of the suggestions worked to make it appear. I'm not going to mess with that one too much as Firefox is already the default browser so I'll be fine unless it somehow gets changed.

Thanks for your help.
