I appreciate the Tor Browser's privacy features, but I don't want to run my data through the tor network. Instead I have a socks5 proxy I'd like to use.

I've tried disabling the TorLauncher addon, which allows me to use TorBrowser normally without a proxy. If I try to add my proxy however, I get the "Unable to find the proxy server" error page.

If I use the same exact proxy settings in a normal Firefox browser, the connection works.

Is there some sort of hidden setting specific to TorBrowser that's causing this behavior? Alternatively, is it possible to replicate TorBrowser's privacy settings in a normal Firefox instance?(afaik TorButton is no longer released separately)
