Mozilla Firefox 2.0.0.14 is now available.  The update is a security and stability release and this explains why Firefox users might have been seeing more crashes than usual.

Fixes for security problems in the JavaScript engine described in MFSA 2008-15 (CVE-2008-1237) introduced a stability problem, where some users experienced crashes during JavaScript garbage collection. This is being fixed primarily to address stability concerns.

I knew something wasn't right with my favorite Web browser.  You can download the latest Firefox (and Thunderbird) at Mozilla.com.
