Great add-on!

But I first have to report a bug to you. It seems, that the synchronization is broken in Firefox 4.

Also I have some suggestions for you:

1. Change the font color
2. Change the color of background and font color by using a pipette function, like it is used in every photo editor.

This review is for a previous version of the add-on (0.7.0.3.1-signed).
