There's a bug in this version of Firefox where it prioritizes Socks over Http proxies. If you don't proxy all protocols and ensure that the Socks settings are empty then the world should be a better place.

Hi, As Gabriel has noted Firefox version 71 has a bug in it (https://bugzilla.mozilla.org/show_bug.cgi?id=1601871). Please either use a different browser, change the settings as noted by Gabriel or use FoxyProxy to configure the browser proxy settings.
