Really useful, but missing some customization options Rated 4 out of 5 stars

This extension is great and makes it really easier to sort things up.
There are 3 changes i would wish for:
* A darker theme that with the shape of standard. (Can be done by editing the userChrome file of firefox), which is quite a pain).
* A way to make each tab thicker. I find they are too thin and it makes it harder to move / click them (Again, can be done by editing the userChrome file of firefox)
* An option that disable the way tabs move around when you try to click and drag them.

Still, it's great, thank you

Can't live without tree tabs structure Rated 5 out of 5 stars

This is a must addon for my websurfing. If firefox becomes incompatible with this addon I'd probably switch to firefox fork that is still able to run Tree Style Tab.

I hope for WebExtention of this plugin Rated 5 out of 5 stars

I can't live without that addon. Firefox is only one browser who can handle my bulk work with 100-800 tabs every day, this kind of tabs I can't handle if firefox show them in one line and with that addon I can simply group it in dozens of group and access to them clearly and fastly. If that addon will not ported I will take a hit in my work and slow down. So I hope for not stopping support. May be donate if you need.

WebExtension port Rated 5 out of 5 stars

I'm sharing Blearn's thoughts

I love this addon and have been recommending it to my friends for some time

It doesn't work anymore in Nightly 57.

Great add-on. *Please* port to WebExtension! Rated 4 out of 5 stars

This is my favorite plugin for organizing tabs. It's lightweight enough to always be smooth. I've never had buggy experiences or lost my tabs/structure (unlike all other tab plugins I've tried).

However I started seeing buggy behavior after I updated to FF 55+. The tree structure unexpectedly flattens and *sometimes* restores the structure afterwards.. Just odd behavior. I hope this plugin is ported to the WebExtension API so I can still use it after FF 57 is released.

THE best add-on. Everyone gets excited when they see my screen Rated 5 out of 5 stars

Every time I show my screen to a coworker, they ask "Where can I get that?" Today, though, It was a real bummer when I had to tell someone that it's scheduled to be broken in a few weeks because mozilla is dropping legacy add-on support.

Of course they ask "Does it exist for chrome?" and the answer is no, but soon it will be "no" for firefox as well. Without this, firefox is not barely any better than chrome.

Problem after upgrading to 56.0b1 (64-bit) Rated 5 out of 5 stars

This addon doesn't work with FF for developers version 56.0b1 (64-bit).

firefox55でタブの表示がおかしくなる Rated 5 out of 5 stars


Best thing since sliced bread Rated 5 out of 5 stars

For me this is the best add-on ever.
Since computer screens seem to get wider and wider it is more important to make use of this real estate.

The default tab-bar gets overcrowded after only a small number of tabs and takes a relative large amount of space (especially since most websites are still browsed top to bottom).
That combined with the ordered child-tabs makes this plugin absolutely necessary for any power-user of the web.

I really hope this plugin will remain to be available in future versions of firefox, as my browsing experience would be completely broken without it.

Thanks a lot for the hard work Piro!

this is an essential add-on Rated 5 out of 5 stars

but it's partially broken in FF 55. Pleeeeeeease can it be fixed? Lots of people including myself would be very grateful. Thank you.

Add Support Firefox 57+ Rated 5 out of 5 stars

Excellent addon. The only thing stopping me from going to Chrome. Can the developer add support to firefox 57+ please. The addon already stopped working in nightly.

Switching to Tree Tabs Rated 2 out of 5 stars

Because of a lack of support for Firefox 57+ and far too many bugs, I am forced to switch to an addon, "Tree Tabs" which is fully 57+ compatible, but which has many less features because it is a brand new implementation of basically the same functionality. I hope Tree Style Tabs would update to 57+, but for now, I'm going with Tree Tabs.

Close button on the left? Rated 4 out of 5 stars

Hi, this is a really use plugin. I especially like the auto-shrink feature. However, with auto-shinking things become a bit annoying when I need to close a tab. Because the close button is on the right, I have to click it quick enough so that it won't jump to its location after the tab bar is expanded. I guess placing the button on the left will solve this issue, however, I can't find such an option. Add it, please!
