Memory safety bugs fixed in Firefox 55 and Firefox ESR 52.3
these packages pull in GCC_REQD+=4.9 via mozilla-common.mk, and
are very widely used (I suspect only www/firefox actually needs it)
this will take care of most of the fallout from major bumping
pkgsrc-gcc-libstdc++ to 7 on netbsd. these are the most widely
used packages setting GCC_REQD>4.8.

FIx hangs when using a proxy with NTLM authentication (bug 1360574)
Mozilla Firefox is a free, open-source and cross-platform web browser
for Windows, Linux, MacOS X and many other operating systems.
It is fast and easy to use, and offers many advantages over other web
browsers, such as tabbed browsing and the ability to block pop-up
windows.
Firefox also offers excellent bookmark and history management, and it
can be extended by developers using industry standards such as XML,
CSS, JavaScript, C++, etc. Many extensions are available.
