>Description:
I use a lot firefox with the pentadactyl add-on ( http://dactyl.sourceforge.net/pentadactyl/ )

After upgrading from firefox-7.0.1_1 to	firefox-7.0.1_2, the add-on stopped working.
The run logs of firefox show some errors: resource://dactyl-ce6854d61/base.jsm:1270: InternalError: too much recursion

The devs of the addon have no idea what happens ( http://groups.google.com/group/pentadactyl/browse_thread/thread/95da835e687849c2/36b996c48124b5c9?show_docid=36b996c48124b5c9&pli=1 )

The problem stays with firefox-7.0.1_3, but when I reinstall my old firefox-7.0.1_1, then the addon works.

I doubt this is an upstream bug, or more people would experience it, and I seem to be the only one (yet).
Maybe it's a bug introduced in porting firefox to freebsd?

I tried running firefox from a new account, the same behaviour is observed.
>How-To-Repeat:
Install firefox-7.0.1_2 or firefox-7.0.1_3, then the addon pentadactyl.
