At my office, there is a proxy to access internet. When a site is blocked by blue coat filter, I launch putty to open a tunnel to my webserver and I launch firefox portable using my tunnel as a proxy. I used to do it using chrome, but the enterprise has set a policy to block configuration of chrome proxy (like internet explorer). firefox is the only browser that allows uncensored (and private) internet access in my office. At my house (ubuntu gnome), windows firefox on wine is the only way I have found to access some webTV based on flash.
