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

Doesn't work at all for me.

Seems to work. UI is a bit too clunky for my liking, but I only use this once in a while so it's fine.

Has WAY better performance than the other regex search extensions I've found, especially on large pages!!! I appreciate the built-in regex cheat sheet, too.

Two downsides: It doesn't scroll to the results on the page, and I'd like a way to keep the extension open while interacting with the page.

Doesn't work. I couldn't get it to work at all even with simple searches.

It demands only one small permission, the permission to write data into the clipboard. An excellent example of a powerful app that asks for no security hole.

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!

Thanks! I used to find videos with a lot of views on a Youtube page where sort by popularity wasn't displayed. For Youtube in French : [5-9][0-9]{2,}\s+k\s+vues

Well it works which is really nice but it can freeze the entire browser if you force it too much.

pls link to something that explains custom templates, the screenshots arent very readable

This certainly works, but unfortunately it appears to have a lot of performance issues. Even when not in use it can cause pages to stop responding.

It also doesn't provide any feedback when an invalid pattern is used etc.
