OK... I just went and tried to install the Brave earlier after I posted that. But that file link they give in that instructional was bad and couldn’t find it. Sorry about that. Give it a shot if you like and see if it works for you. In the mean time I will look for a link that is correct for the Brave download file.
I’m having a similar problem loading the TOR browser. Can’t seem to get it to work on my system for some reason. Not a big deal because I don’t go to the dark web but I would still like it to be an option. On the other hand the dark web is good place to get hacked so maybe it’s a good thing.
