Firefox plus local websites

I'm getting frustrated. Firefox has crashed twice this morning causing me to lose a bunch of work.

The first time I was working on a post about D209 and the Proviso Township High Schools website triggered Firefox crashing.

The second time I was working on the template for this website and opening ForestPark.com resulted in Firefox crashing.

Any suggestions?

What do you recommend including on the template?

* blogs
* taxing bodies
* elected officials
* media
* reference information
