I please, you would improve more the performance
My PC Alienware 17-r5 Windows 10 (19041.450)
+ a search function (duplicate tabs etc. like All Tabs Helper)
Thank you

you get the 5th star if you mention (on the first description line / permissions list somehow) that you only want to send one notification requesting feedback in the future

Useful, Professional look, customizable and supports 3º party addons.

There is something weird compared to other vertical tab managers and is that there is no filter bar. I hope that there will be one in the future in TST or as TST's addon.

I got a notifcation about "noticable changes to Tree Style Tabs" that said "click here to read about it", but clicking the notification did nothing.

And then all the tabs became suddenly un-styled.

Version 3.5.17 removed both of the dark theme options. I refuse to use a light theme, & so reverted to Version 3.5.13 (the latest predecessor).

Otherwise the extension is pretty cool.

Absolutely love this extension, however it says I can't add it to firefox because it's corrupt. Any suggestions?

長らく愛用させて頂いてます。
　タブのスクロールバーだけをタブの右側に配置する設定ができれば、大変嬉しいです。
　タブは右側に設置していますが、ツリー構造は左側にあるときと同じ形が好きです。この場合、ページのスクロールバーとタブのスクロールバーが並んでしまい、操作のときに混乱するのです。ご検討いただければ幸いです。

With a tab search it'd be perfect.
And maybe an option to hide the native FF tab bar.

excellente extension

Close button on tab doesn't work with latest (3.4.1) version.

nice addon!!!!!

Can I disable notification in the lower left corner?
