Well, This Add-on may have problems with some Stylish Scripts (with skinning scripts in the most of cases).

Stylish is another Firefox Add-on

In this moment, I know that the Script "Gmail Redesigned (by Globex Designs)" have problems, the text editor is always on top, so the signature prev.box couldn't be seen.

I Don't know how to fix that script (I think that could be easy, maybe something about the bakground image box); if you want to see its content, please go to...

...and show me the solution, please :)

I know that in this case the problem is the Stilish Script, but...

Believe in me... is possible that new problems with new scripts are comming :(

Thank you so much.
