Have you ever wanted to get something for free but you couldn't because you didn't knew how to use a manual proxy?
Well, I dediced to explain how to use it on Mozilla Firefox.
Follow the steps:
1. Open Moxilla Firefox, go to Tools and click Options
2. At the Options tab, click Advanced
3. Click Settings
4. At the Settings, click Manual Proxy Configuration. Than put the proxy and the port as shown in the picture.
5. Simply click OK and use it as normally when you want to get something for free.
P.S: Clearing all the browsing data (history) will help the proxy work faster.
Hope I helped :)
