Suddenly my Firefox cannot open saved .htm/.html files on my pc but Edge can. I don't know when this happened but probably during the last month or so. When I try to open a saved .htm or .html file Win10 gives me a "Windows cannot find (path and file name)" error. If I "OPEN WITH" Edge it works just fine. I've checked my default apps and file type associations and they are all properly set to Firefox. I did a RESTART in Firefox but that was no help. Is this actually a Windows problem, or do I need to do a complete uninstall and reinstall of Firefox? Currently running Win10 (64-bit) and Firefox 126.0.1 (64-bit).
