I don't know how to reproduce this but twice now xstandard has crashed my Firefox 3.0.1. Lost a page long blog, oh well.
Some Joomla users appear to also be having crash issues with xstandard and some of them point to bad php on the CMS side.

henrrrik commentedI doubt that it's a server side issue. Judging from the last comments in that thread it seems that it might be the XStandard plug-in colliding with one or more Firefox extensions.

kylehase commentedDamn, I got a ton of extensions. Since all my other add-ons work just fine I'm going to just ditch xstandard for now and use another editor. Hopefully those Joomla guys narrow it down and I'll decide if it's something I can live without.
