I often open multi FF windows. Every start up FF it will display Tree sidebars from all those windows. Then I have to undisplay Tree sidebars on some windows because those windows are just targeted to have very little opened tabs. Only main window for Tree sidebar. Does it have an option to save on/off thing?

Love the extension in general but please let us turn off the new 'New Tab' context menu option. We are used to 'reload' being the top selection and the 'New Tab' at the top has changed our workflow. Thanks!

Super happy with this addon, it's a must have for me. It really boosts my productivity. Awesome job!

Great for someone like me who has a million tabs open at any given time.

I'd probably not use Firefox without this extension. Good quality, helpful developer, crazy customizability.

Jan 30, ver 3.9.21, all tabs disappear. It so confuse.

This is really awesome. One of the most useful addons. With pastebin it can be used as a notebook tree, similar to cherrytree

Excellent extension. Suggestion: a folder/workspace management allowing: (re)naming of folders, (re)assign a tab or a tab tree to a folder, activating or not a folder, assign a(many) folder(s) to a window, manage subfolders. I'm using TST for years and enjoy ;) Could help to specify this set of suggestions.

LOVE IT

This is hands down the best extension for Firefox. The end.

Grazie mille. Molto molto ben fatto!
