There is a new, free, Web browser for the Macintosh, and this browser is really interesting.
Why? Well in addition to a BUNCH of really great features, such as ad blocking, download acceleration, anti-tracking, protection from malicious Web sites, etc....
this browser has a built-in (free) VPN (a rare feature), and it's the only browser currently that automatically scans your downloads for malware!!!
UR Browser (free)
The UR Browser is based on Chromium, and it's already 64-bit. I've been testing it, and so far it's FAST and has good compatibility with various Web sites.
