This is just an amazing extension, it makes management of tabs seamless, well organized and visually intuitive

Had similar issues to another user. Upon opening new tabs from existing tabs, they always went to weird places (to the far right usually) instead of opening next to the tab I was using. This made the addon quite unusable to me...

BUT, I found this can be changed in Manage addon -> Options. At "Tabs opened from Existing Tabs", change "Last Child of the parent tab (recommended)" to "Child of the parent tab, next to the recently opened child (simulates the browser's default behavior)".

So I will continue using this for now. However, it might be a good idea to edit the default so it's more similar to the browser's default, I feel like most people can't be bothered to dive into the options/settings.

Great, but it needs a search bar, to look for the tab you can't find (because there are too many, or because it is in a collapsed group).

Extremely useful for organisation

However, it does often glitch in one particular way. I keep it on the right side of my desktop, but sometimes the formatting gets messed up where the crosses all appear on the left and the down arrows on the right, with no indentations below each tree, undermining its utility

閉じたタブを開き直す で最後に閉じたタブだけじゃなくて直近10件くらいから選択できたら嬉しい

This is so great, but it could be much better if you could rename the trees for better organization, just like the folders in Google Chrome or Brave. I found this extension almost perfect, the only thing missing is that it's very easy to get lost without opening a search tab to be the "father" of the tree, for example, opening a search on Google and for emails, and inside the tree, put the emails that I use both personally and for work.

I can't live without it! I only miss it had tab search and a tab counter.

Nice, although a bit slow every time when it's opened.
A live search/filter on top would be great (getting focus when side bar is opened)

Been using this extension for years and it is amazing. Wasn't sure where else to report this but recently the scroll bar has disappeared making it difficult to navigate.

Works great, just wasn't for me and created a lot of lag.

I've been using this extension at work for over a year now. It is perfect for when you need to work in many tabs at once. But for my personal computer I don't find it necessary, and prefer to use classic horizontal tabs.

I like it a lot, but the lack of a keybind to toggle showing the tree-style navigation bar is killing me. I have checked the plugin settings, and the plugin page, and seen no shortcuts listed, so it seems this feature isn't currently (2024.09.10) supported.

4 instead of 5 due to the last Permission the user has to grant the ad-on, while other iterations of same utility do not go past recognizing a tab, without gathering data. As per the pages detailed explanation of the permission, which stands at the top, quote, pursuant to the date of posting this review, and not at fault should they change the source code to avoid being, in lay term, a keylogger. : "Access your data for all websites

The extension could read the content of any web page you visit, as well as data you enter into those web pages, such as usernames and passwords.

Extensions requesting this permission might:

Read product and price information from a page to help find you the best price on items you're shopping for
Offer a password manager that reads and writes details of your username and password
