I just cannot understand why FF is the only browser which has such handy plugin!

awesome!

Absolutely essential. I've used this extension for more than 5 years and refuse to ever browse without it. The best of all the vertical tab applications and really should be the STANDARD way to browse now that we all have wide screen monitors. Nothing else makes sense.

This add-on is one of the main reasons I use Firefox over any other browser.

I use LOTS of tabs. Having grouped tabs, with a tree structure (like a filesystem) is the most sane way to manage having lots of tabs open. I cannot understand why this isn't default behavior. This is the first extension I install immediately after installing Firefox. Every. Single. Time.

This is the single most useful add-in for Firefox, and is actually the major reason that I still use Firefox as my primary browser. The ability to organize tabs into groups so that I can manage tasks, and easily switch between groups related to the various tasks and projects that I am working on makes my life so much easier. If you have more than a few dozen tabs this becomes the _only_ way to effectively manage them. It's so useful that it's used by pretty much every developer in our organization.

Great addon , please add :
- mousewheel scrolling in the tabs
- color for groups of tabs (a click on a link opens a new tab in the same color of the current tab)
- Tabs counter on the top or bottom of the side bar
- smaller sidebar Title (it takes the size of almost 2 tabs)
- a tutorial on the web page of the addon to explain how to remove the native horizontal tab bar

Thanks for the work on it !

Tut, was angegeben ist. Tolle Idee!

Incredible extension. Not only does it deliver on its promise of tree-organization for tabs, but it also keeps up with other Firefox features like container tabs and even tab hiding! There has clearly been a lot of love and thought put into this extension to not only make it usable, but to make it feel like a native Firefox feature instead of a third-party extension. Its customization options are fantastic too, including the much-appreciated ability to tweak its CSS. Great work all around.

One Missing feature: New Tabs always on top of the tree, not at bottom of the tree (be the first one!).

Piro’s TST solution is working well for me.

What I wanted is a visual way to capture my trail as I browse, and that’s what it does. Attempting to try to turn it into tab organizer tends to lead to frustration. I find that a useful constraint—otherwise I’d be organizing tabs all day instead of researching things.

I put TST sidebar on the right, I use “Right side” style of contents, and RTL text direction. Even though I generally browse in English, the general alignment of things with these settings appears to work best for me so far.

I provision custom user chrome CSS in my Firefox profile (hopefully this keeps working) to hide the now-redundant default FF horizontal tab bar and TST sidebar header. I also used TST’s debug mode to tweak a bunch of settings and added bits of custom TST CSS to achieve the desired look & feel (samples in TST’s GitHub repo were a useful starting point).

I use TST with Conex, switching between containers and only showing tabs from currently selected container. I believe I had to fiddle with TST settings a bit to make it work together with Conex smoother, otherwise tabs within the same tree were opening in different containers. (I think it is not TST’s problem that with default settings visual hierarchy gets messed up if tab hiding is on.) In the end it’s hard to keep track of my tweaks and which of them are relevant as the extension gets updated, but it works nicely now.

I wish for an easy way to dump a tree of tabs into bookmarks while preserving the hierarchy in some way (even if it doesn’t let me restore the tree). The primary challenge appears to be that in Firefox a bookmark folder can’t itself be a bookmark, while in TST a tab holds other tabs.

I do encounter a situation where after Nightly’s update & restart, the TST sidebar never gets loaded. Just quitting the browser and opening it again fixes that. So far I haven’t lost tabs and never had tab hierarchy mess up on me, even though I was using pre-release TST builds from GitHub for a while until 2.4.20 came out.
