Sorting Feature Rated 4 out of 5 stars

Great in many ways. Needs a sorting feature.

Ie. ability to sort tabs by domain (for instance to gather all tabs in a single tree)

Very useful, I like it. Thank you!

Rated 5 out of 5 stars

One of the best addons, because you can have many tabs and have still a overview. I like it

Tree Style Tabs Rated 5 out of 5 stars

Tree Style Tabs is the #1 most useful and powerful add-on I have found. With it, Tab Groups, and Tab Groups Menu, I am able to manage several hundred websites, each in a task group as a parent with its own child links and pages. Tab Groups and Tab Groups Menu facilitate managing that large number of tabs. And that is all in one instance of Firefox.

Essential Rated 5 out of 5 stars

One of the most useful addons

Need extra options when clicking links Rated 5 out of 5 stars

Excellent add-on. Very helpful for managing many tabs.

I saw in the add-on description that automatic generation of tab trees can be disabled, however I would like to suggest two alternatives to this (both would be greatly appreciated):

1. If possible, please add the following 3 options to the menu box that appears when right-clicking on a link: 1. "Open as independent tab"; 2. "Open as child of current tab"; and 3."Open as sibling of current tab". These would be immensely helpful in providing the option to open new tabs from web-page links as either independent, sibling or child tabs. (Note, I am not sure what a sibling tab is, but I am assuming it is a tab that opens at the same 'level' as the current tab. Further, it would be ideal if right-clicking a link to "Open as sibling of current tab" when the current tab is already at the highest 'level' (i.e., at the same 'level' as a new independent tab), that this new sibling tab would open at the closest position below the current tab at the same level as the current tab (i.e., immediately below the children, if any, of the current tab).

2. It would be helpful to add in the preferences of this add-on, the option to set the level at which new tabs from links are opened. Something like this: "Middle- (or left-) click on links opens new tab as independent/child/sibling of current tab".

Thanks again for an outstanding add-on

Excellent add on, very useful. It would be great if we had the option to make the parent tabs more visible, like different colors or bigger icon.

Best Extension Ever Rated 5 out of 5 stars

I don't normally leave reviews for extensions, but this is the best extension of all time. This is the only reason to use Firefox. Hopefully this extension will continue after the release of Firefox57 on Waterfox or a similar Firefox alternative. Tree Style Tab allows me to have 50+ tabs open at any one time, especially when I'm at work or just researching generally in my spare time.

This extension makes Firefox the best browser there is. Generally, the other extensions for other browsers implement this feature in a clunky way. The web API doesn't work well with implementing tabs. This extension implements it beautifully and in a native-ish way.

Thank you for creating this extension.

RAM usage Rated 2 out of 5 stars

Firefox with TreeStyleTab uses much more RAM and makes it to respond extremely slow.

there is many annoying bugs after update Rated 4 out of 5 stars

After updating FF no matter which option I choose, it opens the new tab as a child of the current one.
Also Incorrectly placed the tab bar after start.
Please fix it, your addon was very easy and useful before.

Best app on the planet Rated 5 out of 5 stars

I mean it. Please make sure that will be compatible with Firefox 57+. I can't live without this app!

The reason I use Firefox Rated 5 out of 5 stars

Would like to switch to Chrome, but Chrome (including the extensions) does not have acceptable tree-style tab support.

The most important add-on: it singlehandedly makes firefox the best Rated 5 out of 5 stars

Allowing this browser extension to work is the most important firefox feature,** because tree style tab is the the most innovative and important benefit to web browser productivity since the invention of tabs. Other add-ons have tried to match, but none have been able to. Vertical tabs are not enough - the full featured, collapsible, multi-tiered tree is what unlocks your browser and makes it a tab managing system. All browsers without Tree Style Tab are identically lackluster by comparison.

Sadly I can only give 5 stars, or I'd have given it a million stars.

More important than e10s, for sure.

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

I switch between so many tabs all the time, not finishing reading, but intending to go back and read those tabs later. This makes that so much easier for me! I love that I can also bookmark tab trees/groups so that I can lessen the amount of tabs I have open (which does slow down my browser, but that's my fault for having so many open).

Question: Is anyone developing a version that will work once Firefox 57 is active? I know that they're going to be using WebExtensions exclusively, which means that XUL-based add-ons like Tree-Style-Tabs won't work. That's my only criticism of this add-on, is that I want it to work with FF 57, but, knowing that it's XUL-based means that it won't unless someone is developing something to replace it. I'm not proficient in computer languages, coding, or software development, otherwise I would totally do it myself.

Good app, but wondered if you guys can make it better. Rated 3 out of 5 stars

Good app, but wondered if you guys can make it better. This could be the overall best Tabs tool, but unless I missed in the limited options
Could not find a way, or addon suggestion or feedback options, to do these very simple , but badly needed features below.Thank you!
1. As mentioned by others, this app does get very buggy at times, does not work correctly.Many times when simply
Trying to copy and paste certain Tabs with title to back up, will not work on my new WIN 10 64BIT pc, shows blank when try to paste in to Onenote.
Needs easier better Tab Back up features to poss add this feature to make easier & save time for Tree tab clients to select multiple
(SELECT TABS,or URLs Only- In desired order-Not consecutive order only), if do not need To save all, and save or backup
into PC folder, external drive or Onenote, without having to download all saved tabs.
2. Badly needs option to Navigate many tabs more easily, like many times we may have a few hundred tabs open, Need options to jump to Top , Bottom ,
or Search Within all tabs to go to specific Tab, without having to scroll thru hundreds of tabs each time, just to find specific ones.
3. TAB Tree appearance is too limited, all few hundred Tabs, all blend together, hard to view, Badly need an instant preview, of Theme changes,
have to keep opening and closing Theme options to see changes, but cannot find an easier view theme for all my tabs.
Again these Hot addtl basic features, would make this program one or, if not the top best online programs out there,
and I would gladly make a donation, and leave your programs All excellent reviews online as well.

Need Update for Firefox 53 x64 Rated 3 out of 5 stars

Normally it's a 5-star. But after updating to FF53 x64 version, no matter which option I choose, it opens the new tab as a child of the current one. This is pretty annoying.
