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

Can this extension be used to capture information about a FF tab that somehow opens then closes within a second? If so, what settings of this extension will enable this?...I haven't been able to find the correct setting to capture this info.

This extension revolutionized my browser experience. I can work and search much, much better now.
Gonna test this with vertical tabs on the browser soon to see how it goes

been using this for a couple years now and it's incredibly nice to see all my (many, many) tabs organized into little branches. great to use with Auto Tab Discard

Muy buena ayuda
