Great extension, but not looking right in FF55 Rated 4 out of 5 stars

Great extension! One of my go-to add-ons for new installs.

Had to do a refresh for FF 55 and when it reloaded the "Mixed" Skin is showing the same as the "Flat" skin. Also needs to be updated for the 57+ FF update rules.

They'll pry my tree-style tabs from my cold, dead hands Pt.2 Rated 5 out of 5 stars

I just wanted to validate and confirm the pain of the previous reviewer in response to opening the new fireox to a shitty row of horizontal, unorganized tabs. I love you Tree Style Tab.

They'll pry my tree-style tabs from my cold, dead hands Rated 5 out of 5 stars

Occasionally I will have to work in an environment that's not my own and the most painful part is dealing with 300 horizontal tabs that only can show the favicon with no hierarchy.

Best add-on for managing tabs Rated 5 out of 5 stars

I love opening a hundred of tabs. And I really adore this add-on! It helps me to keep all tabs sorted by my taste and which is more important - it saves my time looking for the tab I do need right in time.
Thanks a lot for providing and supporting this product!
I hope you update the addon for further comfortable work in new versions of FF 57+!

Keystone of addons. Rated 5 out of 5 stars

Thanks alot for reworking it for WebExst, was realy worried about some devs abandon their addons due to chromifications and lack of time to completle rewrite code, if its possible at all.
I use TST since 2008 and absolutle love it.

Does not work any more on FF 55.0.x Rated 2 out of 5 stars

After updating FF from 54.0.1 to 55.0.3 it does not work any more.
Tree is broken, groupings work with problems, roots and children of groups is mixed up and change their position.
In sum tree does not work like before.
And I can`t understand how to reset settings and tree to default. Maybe this would help.
Mark before - 5+, now - 2.
P.S. Who know how to reset settings of this add-on, please write in comments.
P.S.S. After reverting to FF 54.0.1 everything is fine again. Will wait for fix.

Forgets all tabs between each session Rated 1 out of 5 stars

Recently broken (Firefox 52.0.2).
After some digging I found that this addon is the one responsible for forgetting all my tabs. Every time I close and reopen firefox I get lots of about:blank-pages instead of remembering my tabs from last time.It works fine if you never close your browser.
I used to love this add-on, but this makes it unusable.

The most important add-on for Firefox Rated 5 out of 5 stars

This adds the key capability that differentiates Firefox from other browsers. Some have a similar characteristic (Vivaldi) but suffer from the flaws in the Chromium browser.
I cannot continue with Firefox 57 if this extension is not updated to be compatible. It is essential.
Without it, I will not update to FF57, and/or will have to make do with Vivaldi.

My Essential Firefox Addon Rated 5 out of 5 stars

Fundamentally changed how I use the internet and conduct my research. Took some time to evolve my workflow, but it truly is a remarkable productivity multiplier.

200+ tabs across 8 windows is my norm, and it feels like the most natural way to work. Can't imagine trying to browse any other way. My wholehearted thanks to Piro.

Great addon. One issue - If I manually collapse the tab bar, I can't seem to get it back. I have to restart Firefox at that point.

Firefox57からは機能不調 Rated 5 out of 5 stars

最高のAdd-onですが、Firefox57から本体の仕様が変わったらしく、
1. 起動時にツリー状態が再現されずフラットに並んで表示されます
2. タブを掴んで移動しようとしても階層移動できません

今はもうFirefox57をFirefox54に戻して自動更新されないようにしてます。

ツリー型タブがアップデートされてFirefox57に対応される日をお待ちしてます

Great but missing some key features Rated 5 out of 5 stars

Awesome addon, cleans up the work space a ton. But i would really like to see a setting to allow you to adjust the size of the tabs. Perhaps a scaling bar setting? On a 4k monitor the tabs and text are extremely tiny!

Compatibility with MuteLinks Rated 5 out of 5 stars

Hello,
Seems that the last version is not compatible with MuteLinks addon (see my comment on this addon page https://addons.mozilla.org/en-US/firefox/addon/mutelinks/?src=userprofile , and the dev's reply)

Could you check what is wrong ? I really like your addon that I use since many years.

Thanks
