Yep, I've been using TreeStyleTabs for years and years and it is the single most useful addon I have ever used in my life and is also what will keep me using Firefox over every other browser indefinitely. Every other browser feels like a toy without TST. I'd highly recommend everyone check out TST and give it a whirl. It is especially useful when you are researching something on the web due to how well it supports hierarchical, collapsible tab groupings. https://addons.mozilla.org/en-US/firefox/addon/tree-style-tab/ https://addons.mozilla.org/en-US/firefox/addon/tree-style-ta...
