I keep getting a pop-up error message about an expired certificate from jetpackgallery.mozillalabs.com.443. The certificate expired on 08/13/2011, and I've been getting this message constantly ever since. It just pops up, regardless of what I am doing, even when Firefox is not the active application. The details say that it is from Equifax. I'm using version 3.6.2 on a G3 Mac laptop, OS 10.4.6.

Enough of this garbage! How can I block this dang certificate!?!

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

Thanks, I found jetpack in the add-ons and disabled it. Haven't seen the error message all day.
