How to Set Up and Use a Firefox Proxy for Better Privacy? or Is a Firefox Proxy the Best Way to Brows

Yo!

Double-check the port numbers in your firefox proxy settings. I once spent hours debugging only to realize I typo’d the port lol.

Also, some proxies don’t play nice with IPv6. Go to about:config and search for "ipv6"—disable it if enabled.

If all else fails, maybe your proxy is just dead. Test with another one from free-proxy-list.net.
