Most probably.

has a link to the FF 50.0.2 patch which links to the bug discussion

see comment 17:
This file hasn't changed substantially in 5 years, so I imagine all
branches are affected.

Most sites that require javascript I just close that tab.  But yes,
there's a few that I do enable javascript for.. in which case

I do.  Along with requestpolicy continued
  https://addons.mozilla.org/en-US/firefox/addon/requestpolicy-continued/
*AND* I log in as a regular user with no privileges.  The idea  being
that for an exploit to work not only does the exploit have to run on
my machine, it also has to do a privilege elevation before it can do
any serious damage.

When I need to do some admin function like updating software I'll log
out & log back in as the admin.  The downside for some people is
things like the FF/SM automatic update don't work if logged in as a
normal user (which I see as a Good Thing)
