If you want to use putty as a dynamic proxy to go across the firewall, just select "Dynamic" and type any available source port you wish(ie. 9050), then press "Add". Things get done :D
Go to your system proxy setting(ONLY configure in your browser if you want it to be the browser's proxy) , only set the socks v5 proxy as 127.0.0.1:yourport (ie. 127.0.0.1:9050)
Wanna use it to break the firewall in Browsers, then continue reading the information as below otherwise that's all.
If you are using firefox, type about:config in the address bar, then search "remote_dns", set the value to True
If you are using chrome, just install the "Proxy SwitchySharp" extention, remote dns resolve is used by default.
Have fun with your newly setup proxy and have fun bypassing the firewall between your PC and your target hosts.

According to the description of the homepage of Proxifier, the software Privoxy looks like a good recommendation. Privoxy is a proxy application which filters a lot privacy related things (cookies, webbugs etc.). However the software allows you to configure HTTP, SOCKS and other types of software and is very flexible. I am sure that this is a good replacement.
After reading your comment I can go a bit more into detail: The central configuration file is
/etc/privoxy/config. The directory/etc/privoxyhas some other files, too. Theconfigfile is very well documented.Lets assume you want to send all traffic to example.com though proxy-a and all traffic to askubuntu.com through proxy-b. SSL/TLS traffic (HTTPS) should not use any proxy. So you add the following lines:
The keyword
forwardis followed by a site or a pattern. It can be an IP address, hostname or a regular expression. All traffic which matches will be send to the last entry in the line. This the proxy address. When you use a.(a dot) a the end of a line, it means that the pattern before will not use any proxy. You will find more information at the handbook.
