I started using it about two months ago when too many sites started disallowing IE11. Only three problems with it so far.
Can't figure how come once I enter a URL by pasting from somewhere else, to go to it, I have to use the keyboard Enter key. There doesn't seem to be an onscreen Go button for the mouse that I have found. Minor annoyance.
I can't get to one site I've been on for a long time since it wants me to sign in again, but when I do, the site treats me as a newbie and wants me to enter a screen name. When I do, it tells me that screen name is already in use. Not sure if that's a Brave problem or a site problem, but I'll go over there on IE11 and see "What's up with that?"
Migrating APS to Brave from IE11 was no problem whatsoever.
I'm having trouble with the NOAA weather site, but they've changed everything completely around. To what purpose, I cannot fathom, unless they're tailoring it completely for mobile sites or all the weather people in the nation got together and asked them to stop putting all that good information on the net. Boy, I'm getting paranoid about everything, ain't I?
