Amazing extension, saved me a lot of time on my studies.

I love TreeTabs except for 2 things:
1) Sometimes when I click on a tab, instead of just switching to that tab, that tab and any subordinate tabs open in a completely new window. It seems to happen when I click too hard on the tab. Or maybe there's a very slight movement of the cursor when I click.
2) Then when I move the tab and subordinate tabs back to their original place, the tab order is completely reversed.
Other than those two things, TreeTabs is a wonderful extension! It makes it a lot easier to deal with the many tabs I leave open all the time.

Every time the author does something, he does it like an idiot. He adds some stupid crap. Instead of fixing the bugs he wrote about two years ago. No. The author won't fix the bugs. Let's add some stupid, idiotic crap.Why did they make this stupid pin? Now every time I move the tab to the beginning, it automatically pins itself instead of becoming the first one.How do I remove this stupid pin?

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.

This extension is the only reason I am still using Firefox in 2025.
No other browser has automatic tab nesting.
