It only works in simple Pages, that is, without frames or iframes or any other complex structure.

Pretty good, but, could you add options to customice the output? For example: add new line between each occurence in the result box, so we can copy one result per line. THANKS!

Ability to scroll between matches as in the regular Firefox search would make this extension much more useful. Right now trying to find something on a long page is really difficult.

I like the recent Highlight feature that's been available since version 1.0.4 (for some reason only available as a download from the author's GitHub page), but it has one side-effect that has a massive potential of breaking websites. The highlight is not only applied to visible text within tags, but to the whole page ( document.body.innerHTML ). This can break inline JavaScript, link references and all kinds of other things as well if a match is found, which sadly makes it unusable as the multi-word highlighter that I've been looking for.

For other use cases, such as extracting data from the page source, it's a neat extension but I have no such requirements myself.

Does what it promises. Would be great if you could explain the functionality a little bit more. I cant get my head around the template thing.

This extension doesn't do a great job at explaining what it is. I was hoping to be able to search for an expression and highlight results on the page, like cmd+F but with regex instead of simple string matching. This extension basically just greps the HTML for your expression and gives the results.
