I am pissed as all get-out.
Because every time I opened up Firefox, I had to go through an obstacle course of saying "yes" to this thing and that thing and this other thing.
Some of it had to do with making Firefox my default browser--I kept saying "yes," but the little window popped up every time I opened Firefox.
Some of the rest of it had to do with setting up default programs for all file types and protocols--I kept saying apply the ones the computer thinks best, but every damned time I opened up Firefox, I got this again.
I wish I could show photobucket screen-shots, but at this time (3:15 a,m.) photobucket.com appears to be down, so I can't do that.
So.....I "uninstalled" anything having anything to do with Firefox (i.e., anything where the date was listed as 10/24/16) and am back to using Explorer 11 and Microsoft Edge, both of which appear compatible with every web-site.....excepting Skins's island.
Now what should I do? Any suggestions? How come Firefox ignored my instructions about defaults?
Damn.
