How to use Proxy Firewall

Proxy Firewall is an innovative program that requires programs to use a proxy at the socket level. It works with SOCKS 4 & 5 proxies and HTTPS proxies. Also, it will allow you to selectively choose which programs are affected by it. For example, if you're running AIM and FireFox at the same time, you can choose to allow AIM to operate without a proxy and still surf the web safely on FireFox with a proxy. It is also possible to set up proxy chains, and rotate proxies randomly or by time.
The first time using Proxy Firewall can be a little confusing to novices, so here is a basic tutorial on how to use PF (Proxy Firewall).
Get your list of proxies (saved in a .txt doc), and open Proxy Firewall.
Choose the "Open Proxies" tab and click on "Add Proxies". Now, choose "Import" and import your list. Click Okay
Check your proxies with the built in checker. I like to uncheck "Keep bad" as I don't need to keep the bad ones, they're still in the .txt doc.
Open your browser, you will get a popup saying that "{Browser} is trying to connect" and some options. You want to choose, "Use Proxy Server", and from the drop-down on the right "Rotate Open". Click on the radio button for SOCKS or HTTP(S), whichever type you are using, and then "Rotate Randomly" and set the rotation timeout.
Come to this site, and check to ensure that it is showing the proxy's IP address and not your real one. If you see the proxy IP, then you've set it up correctly.
Now you can surf safely knowing that you are not leaving an IP trail everywhere you go. Bear in mind that if your connection seems slow, that's because your speed is only going to be as fast as the proxy server you are using. Often, I'll find the fastest one and just use it for awhile.
