I'm reading one of the adblocking threads today and one other time recently. Both times I see Bluhell Firewall mentioned, so today I tried it. Just amazing! I have a really fast PC. An SSD, Ivybridge 3570K CPU and eight gigs of RAM, yet starting a browser session with Cyberfox or Firefox was never instantaneous. I'd just always assumed it was because of Sandboxie. Memory consumption has been from the low 300,000k to mid 300,000k. It never concerned me since I rarely even ever use two of the eight gigs of RAM. Now a session opens instantly and memory is always the low 200,000k. The developer is getting my $5 donation!
