not working with latest version of firefox. eating up all memory

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.

This extension was working great until recently. Not sure if it was an update to FF that broke it or what. My browser now shows the same tabs at the top as well. Im not sure how to get rid of those.

There's a rare incompatibility with Simple Tab Groups (->STG).
When saving a session in STG, the tree structure of Tree Style Tab (->TST) get lost completely and as a result the stucture is gone.
This happens on :
Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Firefox/102.0
OS Linux 6.1.0-7-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.20-2 (2023-04-08)
OS Theme
and is a quite new problem.
Unfortunately I have no real idea how to check, which of both AddOn's produce the "error"...
Does anybody have an idea?
BTW... the rating will be reset after solving the issue, because I know this AddOn since a long time now and used it many times... sometimes in the past though it came to my attention, rhat there were some incompatibilities from time to time - that's why I post this message here and in STG.

Consistent with the host, but lacks functionality that http://addons.mozilla.org/firefox/addon/sidebery provides.

waarom duits?

It's massively hyped by that one tik-toker. The downsides with using this is that it makes your browsing space smaller. In addition, if you're an impulsive person and accidentally close one browser, then you can wave ALL those tabs gone because your never going to get them back. Also it's a massive hassle to group tabs like this, but the upside is that its easy to keep control of tons of tabs.
