Rated 3 out of 5 stars

Good job, but I hate the red cross at statusbar.

This review is for a previous version of the add-on (0.1.2). 

hmm

it shouldn't normally show a red X
for some languages i haven't been able to add translations so that would give red Xs
you can hide the icon by adding this to the bottom of userchrome.css
#statusbar-display>image{display:none!important}
