One of the better addons out there. Navigating thru a huge number of tabs feels like a breeze with this. Definitely recommended.

I think this might be the best add-on I've ever installed (apart from uBlock Origin ofc). I'm way more organized with this, it's a life-saver!

I do have some suggestions though, the first of which is to have the option of making a tab (or tree) the first child when dropping it on a parent tab (I like to have my latest tabs at the top of trees). This should also go for when a link or string is dropped on a tab (Drag and Drop section).

For my second suggestion, I use an extension called "Search by Youtube-Right Click Menu" and when I look up a term with it, the newly opened YouTube tab is considered an independent tab whereas I would like it to be first child of the current tab (other options would be nice too!). I've tried tweaking the "Tabs opened from Existing Tabs" and "New Tabs not from Existing Tabs" settings but none of them seem to do what I want. I'm not sure how these tabs behave but if it's possible to implement this, it would be pretty cool.

And for my final suggestion, I think it would be nice to add the option to make all the descendants of a tree the first children of said tree. Sometimes, I just keep on creating new tabs which create a new child of a child of a child, etc.

Thanks!

PS: I apologize if those options already exists but I looked for them in the settings and the Extensions extend TST list but couldn't find them.

The functionality is exceptional, with numerous options for controlling side tabs' behavior and organizing them.

The best browser add-on! I can't imagine how I used to live without him. It's amazing why no browser has such functionality built in.

Incredibly useful extension. Thanks for the quick fix with 3.9.22!

Can't live without this add-on! Seriously!

The management tool for all my tabs I have been waiting for. Using it for years and still love it. Awesome.

Отличное дополнение. У кого не работает с 30 января 2024 - переустановите

"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."

Great extension and the latest issue has a workaround provided by the developer.

Quickly fixed after a faulty patch.
Awesome extension.
Has made my tab hoarding problem much worse.
100% recommended

thanks to the people in the reviews for showing the workaround for the bug in the latest update.

With update 3.9.21 it just doesn't work. It doesn't show any tab in the tree when I first lunched Firefox, and left clicking the icon on the toolbar does nothing. Sometimes I managed to open again the extension by disabling and enabling it again, but tabs still won't show. I rolled back to 3.9.20 and it works well again (if memory gives me problems, I'll roll back to 3.9.19). Still, I want to give you 5 stars since I know you will fix this and I love the extension, thank you for it!

Edit: I updated to 3.9.22 and it's fixed, thanks!
