use of menus crashes Firefox?

[Keith Seyffarth]

After updating gtk following (and most other ports) following the
instructions in UPDATING, Firefox now crashes if I click on any
menu. This includes the menus such as "file," "edit," and "help" in the
main menu bar as well as right-clicking or clicking a menu from an
extension.

So far I have tried
rebooting the computer
forcing reinstall of Firefox and dependencies (portupgrade -fR)
deleting firefox using pkg_delete and reinstalling

This seems to be the only thing in the log:
Dec 19 19:35:59 janet kernel: pid 1260 (firefox-bin), uid 1001: exited
on signal 12 (core dumped)


I'm not sure what else to try. Any suggestions?
