ColorfulTabs par Shivanand Sharma

The first addon you should be installing on a fresh Firefox install. A must have. The most beautiful yet the simplest add-on that makes a strong colorful appeal. Colors every tab in a different color and makes them easy to distinguish while beautifying the overall appearance of the interface. An essential. A comment from one of the millions users...

"...Just wanted to let you know I absolutely love your Colorful Tabs add on
for Firefox! It's one of the best and my personal favorite of all add
ons available. Thank you so much for this!..."
