Firefox 'help' does not work, as there is no option for Firefox as a default browser in Windows 10

more options

I have followed the Firefox instructions to set Firefox as my default browser in Windows 10 Pro. When I get to the menu for default browsers, Firefox is not an option. There is an option to find another browser in Windows Store, but Firefox is not in there. It has a Firefox User Guide for £2.70. Firefox keeps asking me to set it as default browser, but it seems impossible. Please help? Terry

Chosen solution

As explained in the Setting Firefox as the default browser does not work - What to do document, if you don't see Firefox as an option in the default browser list, try uninstalling Firefox and then reinstalling Firefox.

This can often force Windows 10 to include Firefox back on the default browser options screen.

Hope this helps.
