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

Wow, thanks for all the suggestions!

Tried the DNS switch and disabling IPv6—no luck yet.

But launching Firefox in Troubleshoot Mode actually worked?? Guess one of my extensions was messing with the firefox proxy. Time to play detective with my add-ons...

Any way to pinpoint which extension is the culprit without disabling them one by one?

Also, gonna test those free proxies later. Appreciate the help!
