If you type C-g when this happens, does it help to unlock Emacs,
so you don't lose your edits?

If C-g does unlock Emacs, try typing (' again, after setting
debug-on-quit to t.  Then, when you type C-g, Emacs should present a
backtrace, which might help to find the code that hangs.

Anyway, what version of Emacs is that, and what .el file do you use
for the "JavaScript Moz" mode?
