Rated 5 out of 5 stars

5 STARS - as this addon is lightweight @6kb and works perfectly

I'm using it for applying below css style :

This review is for a previous version of the add-on (0.1.6.1-signed). 

Please do not make any more userStyles comments in your reviews. There is a forum at userstyles.org where you can communicate with people. Not only is this the wrong place, but I have no desire to dig through the default theme to figure this out.
