Rated 4 out of 5 stars

Conflicts with (the very popular) All-in-One Sidebar addon; I had both on left hand side and it worked good at first. Suddenly the Tree Style Tab display disappeared and I had to manually (and blindly) switch around the tabs using keyboard shortcuts.
Also, would like an additional "+" add tab button at bottom of tree. It seems to be *either* one in FF regular menu or one in the tree - I'd prefer option to have both.
Other than this, I really like it!

bottom tab bar possition doesn't work Rated 1 out of 5 stars

In FF30 the tab bar disappears if I choose bottom tab bar postion while it is shown if I choose leftside, rightside or top position. Tested on Linux Mint 16.

Excellent extension, thank you developer! Rated 5 out of 5 stars

An excellent extension all around. Thanks to the proliferation of widescreen displays, there is a lot of extra horizontal space for tabs. Moving tabs to a tree saves vertical space, and every little bit helps when you are doing a lot of reading.

Thank you so much, developer!

Best FF addon - But some issues Rated 5 out of 5 stars

As mentioned by The_Frag_Man, this issue has some issues when you have roughly a hundred or more tabs, with tabs being re-ordered after restart.

Also, since upgrading to FF 30, the tree is all distorted once you click on a tab (ctrl-tab restores tree view temporarily). This a a deal-breaker making browsing next to impossible.
As a long-time TreeStyle tab user, I'm hoping this issue will get fixed asap. Happy to assist with troubleshooting if required.

Aside of the above issues, this is the best addon availble to FF. Couldn't be without it. Kudos to the dev for creating/maintaining this great addon!

EDIT: My issue with the distorted tree was caused by some dodgy tabs. Once these were closed, everthing was displayed properly again

#1 Tab Add on! Rated 5 out of 5 stars

A must have for people with TONS of tabs!! Maybe an update though?

Good but some issues Rated 4 out of 5 stars

This is a good addon, almost a must-have but there are two big problems.

1. It becomes too slow with hundreds of tabs open. It may be the incompatibility this guy is talking about here: https://addons.mozilla.org/en-US/firefox/addon/tree-style-tab/reviews/599748/

2. Also with hundreds of tabs the tree doesn't get restored properly making this feature useless. The tabs will get mixed up and display in the wrong order, although it seems they are still associated with the parent tab in some way.

These two issues are pretty critical and need to get looked at!! The performance is fine unless you have a lot of tabs, but managing lots of tabs is what the killer feature of this addon is about.

This is my favorite add-on Rated 5 out of 5 stars

I'm so addicted to it, that I cannot imagine using any different browser. I routinely open tens of tabs while shopping and closing the whole trees with one click is a blessing. Where can I donate?

Rated 5 out of 5 stars

This Add-on is the only reason I (still) use Firefox. And I will until the same feature won't be available in Chrome. Must-have.

Rated 5 out of 5 stars

Does not arrange tabs in tree when Firefox starts with previous opened tabs (FF30-31). Tree is restored by restoring last closed tab.

Not bad Rated 3 out of 5 stars

It’s a nice addon actually.
But with my fair amount of tabs it makes sessionrestore hang and slows down the whole browsers startup by a factor of ~3.
Also I would like the ability to hide the scroll bar completly and remove the useless buttons.

Thanks for this excellent add-on.

I have just a simple feature request, ability to auto hide the bar when only one tab is present. I open windows side-by-side a lot, and this addon makes me shrink it manually everytime.

The must have addon Rated 5 out of 5 stars

The most usefull addon newer seen on other browsers. Please newer stop to support this addon. Can't imagine FFox without it. Would like to donate developer.

The only reason I stick with Firefox..

Nice work Rated 4 out of 5 stars

As title, it's very easy to use when I was browsing tabs and drag and drop to stack them, and the interface looks great.

I would like to recommend adding the function of counting the total number of tabs. It's convinient to find out if it's the time to clean up the tab list.

Rated 2 out of 5 stars

Doesn't play nice with other addons (specifically certain features of tabs mix plus and both unloadtab/bartab*) and is an absolute pain to restyle for something as simple as a color change (why is everything in the css declared with !important and what's going on with the borders?).
Built-in styles tend to glitch in linux. Even those that display well enough have overlap each other, retain border-radius etc.
Often has to be poked a few times before it remembers it's supposed to autohide.

Useful concept and has potential, but it needs polishing. A lot of it.

Most important Firefox Add-on Rated 5 out of 5 stars

I've been using this add-on for years. It's the main reason I stayed with Firefox instead of switching to Chrome when it first came out.

With Firefox 29, double clicking the empty space stopped working. The author explained this well, and simply adding another one of their add-ons fixes the problem, without even restarting: https://addons.mozilla.org/en-US/firefox/addon/tabs-on-bottom

I wish there was a way to contribute a small donation to this author. I hate browsing without Tree Style Tab.

Bug since new update Rated 4 out of 5 stars

Hello !

I have been using Tree Style Tabs on Iceweasel under Debian Wheezy.

But since the last update, Tree Style Tabs just doesn't work properly.

It makes Iceweasel freeze for between 10 and 30 seconds before giving the hand, and it's not possible to use the tabs, some are just hidden, clicking on one brings you to another one, stuff like that.

If you need more info on that bug, please let me know !

Thanks for this great addon by the way :)

A must, cannot use the browser without it.

Tree is lost on restart Rated 5 out of 5 stars

Thanks for this great extension!
But I experience one bug: with all-in-one sidebar extension, I lose tree hierarchy of my tabs on Firefox restart, only when AiOS sidebar is retracted.
Besides, is it possible to add a feature to integrate tabs bar in AiOS? According to AiOS developer ( http://firefox.exxile.net/forum_new/viewtopic.php?f=3&t=10125 ) the only thing to do is to use default Firefox sidebar.
