This extension has been great for a very long time. Easy 5 stars.

The latest update has made it borderline unusable though.
How do I create a new tree? It seems to be completely random, sometimes they just pop up. But dragging one tab onto another seems to be impossible.

In past times I even removed the builtin tab bar. Right now I am seriously considering to remove the addon until the situation is fixed.


EDIT: I have briefly seen, how it's supposed to work. That is all fine.
But there seem to be major bugs right now. Most of the time, like described above, it's not possible to drop a tab onto another tab to create a tree. Also there are super weird interactions between page content and tree pane.
I have disabled the extension for now. Hope to see it back in former glory soon.

firefox keeps crashing after installing the extension.

This has not worked in more than a month. It just loads forever and never works. It used to work perfect. Please fix it.

не работает, просто зависает панель вкладок и висит. нашел решение доп-ние "Sidebery", https://addons.mozilla.org/ru/firefox/addon/sidebery/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search

Suddenly stopped working. Mac Sonoma 14.2.1, FF 122.0 (64-bit)

This is a great extension, one that I've been using for years, but the last update has MAJOR problems. It stoppped working on Firefox ESR 115.7.0esr (64-bits), the workaround suggested by its creator didn't do anything. On Firefox 122.0 (64-bits), the extension was apparently ok, but then I used that workaround giving permissions to "Read and modify bookmarks" preemptively and all my bookmarks were gone. DO NOT USE THE WORKAROUND.

Since the last update (3.9.20/jan 2024), extension slowed down everything, transforming FF in a memory eating black hole.

Please debug ASAP.

Rolled back to 3.9.19 and everything seems to be fine!

Раньше было более-менее нормальное расширение, а с последним обновлением это просто невозможно стало использовать. Жрет память как не всебя. За 7-10 минут использования и перехода по 10-15 вкладкам из 150 сожрал 23 ГИГА ОПЕРАТИВКИ, причем все остальное (дополнения и открытые страницы) уложилось в 4 гигабайта оперативки.

J'ai utilisé l'extension durant 3 semaines et depuis 1 semaine, l'extension à des fuites de mémoire
Ayant l'habitude de jouer avec une page web en fond, cela à fait planter mon pc à plusieurs reprises avant de trouver la cause du problème. C'est inutilisable actuellement et je suis passé à une autre extension.

I estimate that TST, all by itself, nearly doubles Firefox's memory footprint. Sidebery freed up 5-10G of memory for me by comparison (yes, way too many tabs...). TST should *not* be a recommended extension. Latest update of TST leaks memory *very badly* and crashes, taking other Firefox extensions and other desktop programs down with it when the OS starts killing things to free up memory. Sidebery is *much* more responsive & performant with a very large number of tabs. This alone will remove a huge amount of friction in reducing the number of open tabs. No more waiting for TST to catch up. Switching to Sidebery was no problem: all nesting retained. Disable TST. Install Sidebery and verify ok. Remove TST. Done.

Unable to bookamrk

after using ~one mouth going between tabs is lagging so it`s impossible to use

Updating to Firefox 107 breaks autohide tabs feature - it won't work. Very useful but broken addon.

What the smeg ?! It opens the bookmarks sidebar !? How hideous is that ! I was expecting the tabs to cascade from their default position, you know, as actual tabs ! This is mental ! Useless.

There's some memory leak issue with this extension. Keeps using up all of my system's 16 GB RAM.
