Ever since Mr. Kalita had withdrawn the very useful service of surfing via tools.superhit.in, we had to search for new ways out of bypassing firewalls. We had a very powerful firewall / filter called Websense in office. It even blocks access to most common proxy sites. However, the superhit site was innacuous and as such it avoided detection by Websense. Forced into finding a new solution, I found a site that listed four pages of proxy sites. Most of the site listed evaded detection by Websense. So if you have a firewall problem in your office, then try the links from this site Top 20 Free.
