Too much hassle. All I want is to move my tabs from the top to the left side bar. But this add-on does nothing to remove the tabs from the top of your browser. It's pointless. You are required to follow some complex steps which don't even seem to work. Their own github page is out of date, talking about firefox from 100 years ago.

I haven't used firefox for a decade. I thought I'd give version 100 a go, and immediately wanted this add-on. Seeing now why I didn't bother with Firefox anymore. It's decades behind other browsers, as are the addons.

keeps resetting my whole tab collection. I like it a lot , but it keeps doing this every time I open Firefox after bootup
Update: 26.5.2022
Still messing with the structure of the groups. I am so sad, since this is the best way to use tree style tabs. Please fix it

It seemed very promising at first but this extension just did not work for me. Every time I would close Firefox led to losing my tabs and the organisation. The sync function didn't seem to work.

After rebooting computer - all settings gone

leider gibt es das wieder nur in englisch. Ich lebe in Deutschland und wir haben hier die Sprache DEUTSCH! Für mich ist das also nicht zu verwenden!

the best was "All-in-one sidebar"

Не вижу смысла в этом аддоне, так как он не скрывает стандартную панель браузера со страницами

Tried it as I saw it suggested. Tree Style Tab user here, but it's not possible to middle click to close a group of tabs. Maybe if this is implemented I might try again. It feels like this extension maybe tries to do too much?

I only used for about an hour, so maybe that's why?

Totally unusable. It just eats my tabs, and assumes WAY too much about my workflow. A way to turn off the panel stuff would be appreciated—that's what hierarchical tabs are for!

Groups are, just, I mean, *what*? I don't get it. You have to select multiple tabs just to create a folder? This is unprecedented in the history of computers. Even file compression tools let you create empty archives.
