Tree Style Tab also lets you bookmark whole trees. I’m often jumping between different coding languages, or different areas of DevOps on a weekly basis, and tree bookmarks help. I can “file away” a bunch of research and load it all back later, and still have the tree! Very useful for context switching.

Use Vimium add-on and have a pop-up to search your open tab.

Or if you prefer no add-ons or don’t know how to use Vim keybindings then type your search query in the search bar like this:

% my tab title
