Tabkit => Vertical tabs

A post for those who, once tried, cannot live without vertical tabs in FF.

I used to have TabKit installed but this unfortunately does not support FF 4. So I even was very reluctant to switch to the new version as having my browsing (or should I say _research ) _organized, __is one of the crucial parts of my productivity. But turns out there is Vertical Tabs which does almost the same thing. It’s not that polished as TabKit but it “does the thing” and so far I’m happy with it.

UPD: Found the VertTabBar addon also while writing this post… might suite someone more.
