Very good idea unfortunately looks ugly

It's a good addon. I can't use firefox without it. However the recent update seems to be greying out some (but not all?) discarded tab favicons when I already have something to display that they've been discarded.
I tend to recognise tabs in part by favicon colour; is there a way to disable this behaviour? Nothing in the options for Tree Style Tab. Recent updates mentions some 'secret options' and I've no idea how to even access those.

Besides that, Tree Style Tabs sometimes loses the highlight of the active tab, and the only way you can identify it is mousing over all tabs and checking which one doesn't highlight.

worked as advertised, but I didn't sign up for an "ai chatbot." such a feature frankly seems unnecessary, and should be left for extra extensions.

This is probably a great extension for some people, but I couldn't get behind it since I couldn't get rid of my top bar.

un peu compliqué

Overall looks great and works well, but when it's active I can't right-click on tabs to bookmark them. When I try to do this, nothing happens. I tried creating a new profile and the problem is still there. Only when I disable the extension am I able to add bookmarks in this way.

An incredible idea; but could be look a little cleaner and definitely optimised a better, it seems to take up way more memory than other extensions of it's kind. Speaking of similar extensions, Sidebery has a much nicer UI, is less ram-intensive, and has extra supporting-features.

I like the idea but it flickers like mad if you resize it to a small with.

Also there is now an annoying scrolling marquee along the bottom new tab button where it says "Shift-drag will create a link or a bookmark at the place the tab is dropped too". I cannot see a way to turn this off and it's extremely distracting having it moving in the corner of my vision all the time so I will have to disable this extension for now.

does not translate the block selected on the page.

I had no issues since recent update where this extension is using Mac shortcut OptionShift LeftArrow/RightArrow to jump to other tabs.
I constantly use those shortcuts to select text, and not being able to disable them in the extension it's a big no-no. I had to disable the whole extension.

I think this is a great learning experience

I tried the latest version because it looks like a useful extension. I discovered that it would completely reverse the order of the tabs I open with Morning Coffee Quantum, even if I disable all Tree Style Tab's control settings over new tab placement. Eventually I removed the current version and installed v3.9.22 as was suggested by some reviews on this site. It now works correctly, so I will stay with this older version.

All 4* versions, unfortunately, are the worst and impossible to use - they are very large and have many problems. For example, CSS styles of trees is completely destroyed and many other troubles.
I'm staying with version 3.9.22 and hope the author will fix anything that's broken in future attempts.

С 4-ых версий всё поломано и пользовать невозможно стало. Вернулся на 3.9.22 и отключил автообновление.

Depuis quelques jours, il y a beaucoup de bugs, je suis obligé de désinstaller et réinstaller

"Important Note: This version contains fatal issue on the startup. There is a workaround: grant an optional permission "Read and modify bookmarks" for this addon via the addons manager UI. The next release will become working without the permission."

you need to fix this issue ASAP.

Version 3.9.21 is busted and won't load. Click on "See all versions" to download and install the previous version which is working fine.

I wish they could have rolled back this version sooner rather than let it stay broken for everyone. But I don't know the FF addon release process to say if there was a better way to handle it.
