It offers nothing more than the default Firefox search. Contrary to its advertising, there is no "advanced features like highlighted matches, customizable search shortcuts, and intuitive navigation."

Now if it could do just one thing that no one else has been able to do, which is that of keeping the Find bar visibly open on all tabs (as an option), then that would make this rather famous. Evidently, no developers can imagine researchers opening multiple pages in searching for the same things.

But I thank God for what is enabled.

Meanwhile, the "Find in Page with Preview" add on is better.
