Great extension but... Rated 1 out of 5 stars
I think your extension is very useful and also give to Firefox's interface some happy colors but I am really sad to read the license policy.
I was considering the possibility to translate ColorfulTabs 3 in Italian (my native language) but I think my work can be in contrast with your license.
Please Varun, let us able to translate your extension with the structure for localization like the version 126.96.36.199 and most of the available extensions hosted on Firefox Add-ons.
Have a nice day
