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

Not able to group tabs by domain or regular expression.

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

Great idea, decent execution. And for some reason there's an option for "AI Chatbot". I'm very tired of LLM's being jammed in everywhere they can possibly fit. Whether you are fundamentally for or against AI, this is a wasteful and useless implementation.

Muy buena ayuda
