If you have a particular mental issue like I do where you cannot help but open tabs upon tabs without closing prior tabs a lot of the time, then being too lazy to continuously scroll across horizontally to open up squished shortened tabs to see if you should close them, no matter how much coffee you've consumed and then closing the session for the next day, only to repeat the process contributing to your neverending tab collection, then this add on is for you.

I'm not exaggerating when I say this add on is a lifesaver and should be a feature on all browers by default, tabs are elegantly displayed and you can swiftly deduce what is important for further reading and what is unimportant and close them swiftly, trees also automatically form and categorize further if you've branched off from a particular tab, I've just closed 2000+ tabs I've procrastinated closing for approximately 1 month.
