I posted the same question on a general forum, I guess it's a wrong place.
I'm on Mac and looking into BANS. I emailed their support a question if BANS works with Mac. The guy said, that there is some problem using it on Safari.
I hope somebody has some solution, because I don't want to install on my new iMac any other browser. Safari is the perfect lightweight browser, and I had enough of them on PC.
Thanks!
