this is the best thank you

love this addon, i can finally customize firefox as much as id like :D

Upgrading changes my background color scheme without permission. This has happened twice in the past 6 months.

Does a good job from first installation a long time ago, but CAN"T figure out how to restart the %^&#%#$@ editing process !!!!! WHERE is a user instruction ?!?

Em no lo puedo descargar se queda alli sin hacer nada F

AWESOME!!!!
