非常不错的主意！！！！当标签页多起来时，看着原生的标签管理 你会忘了你到底打开了些什么，一团糟。现在一切都好起来了。

This extension is the main reason I use Firefox.

One request: I wish settings/custom CSS would use Firefox Sync.

This extension is one of the reason I keep using Firefox. Makes it easy to use hundreds of tabs. Has all the functions I need and is still in very active development.

Great for organizing tabs. Now this extension and the ones like session managers and tab groups (Panorama) need to integrate with it.

A necessary extension to Firefox. The main reason I use Firefox is for vertical tabs, and this works very very well.

I had a recent problem with TST not initializing, but removing and re-adding the extension fix me right up.

I can finally organize links in a sane way. Bookmarks are too permanent, while just leaving a pile of tabs is too unstructured. This works.

Very helpful with 100+ tabs across multiple windows as it opens a sidebar which is specific to each.

Put it together with Auto Tab Discard and boom!

This has changed my life. I am able to stay on top of tabs much better when I can see them this way. After Firefo Quantum came out, my preferred tree-style tabs add-on no longer worked, and I thought I was banished to an endless sea of horizontal tabs forever...thanks for your work on this!

Lovely extension. I expect to see more improvements in the future. Would be nice if it used ideas from https://chrome.google.com/webstore/detail/quick-tabs/jnjfeinjfmenlddahdjdmgpbokiacbbb?hl=en

An essential extension if you have about 200 tabs open, like me :-)
Thank you so much for your hard work!

you have the best wiki for tree tabs

tabhideにもいち早く対応し、グループのスイッチができる数少ない縦型タブアドオンだと思います。
せっかくtabhideに対応しているので、タブのコンテキストメニューに「Simple Tab Groups」のグループ移動のメニューが出てほしいと思いました。
上部のタブバーを隠すと他のアドオンのコンテキストメニューが開かないので、タブグループの移動ができないのです。

Awesome!

perfect!

Just amazingly useful!

Love the grouping feature and that I can close individual tabs with their own [x] button without having to first navigate to them.

Some ideas:
- Visually maybe it would be best to show each tab's [x] button on hover though
- Should be able to drag left to ungroup (unindent) one level and drag right to group under the previous (above) item
- Also, it would be really if a filter box was on the top to select which tabs to show (filter titles using typed substring). Indentations should be remembered (that is have invisible parents if those are filtered out). If hard to implement, it could at least highlight found items or gray out items not found. Could also have that as option and could have Previous/Next button to select next tab that matches the filter

Been using this add-on for ages, keep up the amazing work!
