great idea!
..but does not work: https://github.com/nabendu82/SearchInTabs/issues/1

didnt work doesnt say searching- nothing after hours

Same extension like Search Word Tabs:

https://addons.mozilla.org/en-US/firefox/addon/search-word-tabs

I think Nabendu, you are the original author.

This app is very useful and easy to use!

It doesn't seem to want to search ebay tabs.
