Comment:

 From #22814:

 Mozilla finally decided to fix this 11 year old bug report and set
 `middlemouse.contentLoadURL` to `false` in Firefox 57:
 https://bugzilla.mozilla.org/show_bug.cgi?id=366945

 I think it would be nice if someone from the TB team backports this easy
 patch,

 It handles Android as well
