Desktop environments are in a bit of a mess at the moment. Arch was maybe a bit too eager with the recent round of updates. But that's why we love it. ;-)
The problem is that pressing any of these key combinations:
volume up
volume down
brightness up
brightness down
super (alone; KDE only)
super+space (GNOME only; changes IBus method)
in both GNOME (3.14.1) and KDE (5.1.0.1-2) causes Firefox and Thunderbird to become completely unresponsive, without any particular increase in CPU or memory usage. This happens whether or not they were in focus. Also, in KDE, the volume control keys don't work.
That list was done by memory, since doing the testing is very tedious.
EDIT: also happens in GNOME when changing IBus method/keyboard layout using the keyboard layout indicator with a mouse. I haven't had a problem with other indicators, and haven't tested on KDE.

I too can confirm this, it is rather annoying.
I use Xmonad as my window manager, but I do have both Gnome and KDE installed.
Nevertheless, just pressing Volume Up and Volume Down is enough to hang firefox, as the OP stated.
Perhaps a bug report?

Do any of you have evince installed, because if so, that might be the problem:

Simply disabling the evince plugin in in Addo-Ons -> Plug-Ins was not enough, btw. I had to remove the /lib/mozilla/plugins/libevbrowserplugin.so to get firefox stable again. The Problems have dissappeared since.

Thanks! Moving that file worked. What does that file do, anyway? I can still see PDFs in the browser.

It's probably there so that the PDFs are displayed by using the evince libraries. But since Firefox has it's own PDF viewer integrated for a while now i don't really see the point either.
