Some versions of Flash on Mac OS X will cause Firefox to crash on pages using the Flash plugin. Adobe has released an updated version of Flash that should fix this.

1. Go to Adobe's Flash download page and follow the instructions to download the latest update of Flash Player.
2. Run the DMG file to mount the disk image.
3. In the Finder, select the Flash Player disk image, and run Adobe Flash Plyer.pkg, to run the installer.
4. Restart Firefox.

Read the Using the Flash plugin with Firefox article for more information about the Flash player plugin or the Firefox crashes article for more help with crashing in Firefox.
