It's better than i thought ! Rated 5 out of 5 stars

I have been a long time tab mix plus user until it was disabled in 3.5. Since then i have downloaded tab kit. The first time i downloaded it i was turned off by it having no session manager and disregarded the useful features. Luckily, since then, a separate add-on called session manager has come out. I hadn't realized that some of the features included no where else would be so useful. I especially enjoy the group manager. The group manager color codes related tabs next to each other, so your tab browsing is quickly organized. And although it would be nice if the tab context menu would be more customizable, i have found the group manager an invaluable tool for someone who often finds himself with many new tabs open. Use tab kit with session manager and multiple tab handler and you have an unbeatable trio.

This review is for a previous version of the add-on (0.5.7).
