message old version
I'm using a 2017 MacBook Pro running OS 10.13.1 with Firefox Quantum 57.0. Most websites give me an error message that I'm running an old version of Firefox. Sites like Facebook & Twitter will only load partial versions without all features, other sites won't load at all.

hi, your useragent (the information the browser sends to websites to identify its version) - apparently mistakenly - shows you're on firefox version 3.5. probably some sort of toolbar or adware has overwritten it. please see here in order to reset the user-agent settings in firefox and fix this problem: How to reset the default user agent on Firefox
