Rated 5 out of 5 stars

Seems nice, but when I tested it with TB24, the preference window just show the option to select the width. I have 4 accounts, no one is detected... PS sorry to post this in the review, but I didn't find a "support email" field.

Update 23 Sep 2013: 1.0.4 perfectly fine now. Thanks!

This review is for a previous version of the add-on (1.0.3). 

Hi, thank you for reporting me the bug.
It was an issue with the changes introduced with the last versions of TB.
I updated BorderColors GT to the version 1.0.4 and it should work now. Please report me if you notice more problems!

PS: Yes I forgot to add my email address for the support. My fault, I just added it. :)
