Firefox is not vulnerable.

Chrome was shown to be vulnerable like 7 years ago but nothing changed.

Closed source stuff like MSIE or Safari? No idea, ask a Windows os OS X user.

MS EDGE, unlike the now hopelessly outdated Internet Explorer, has an open issue tracker. And as Safari is literally just webkit, which also has an open issue tracker, there was no need to pretend to be better than Windows and OSX users by pretending they're on their own.
