Unfortunately it does not work. It finds all instances of a word in a form, but does not replace them.

This is probably my first review on addons, I don't remember if I did one before. DO NOT USE this garbage, it's broken and instead replacing one character with another it replaces entire paragraphs with others, causing me to lose almost an hour of work; I somehow managed to work around it and save it undo-ing hundreds of times and even now I'm not sure if the article is okay, I guess I have to re-read it again!

It would not find anything on any page.

It doesn't work. If the page said, "the cat is black" then I could type in find "cat" and it would say no results. Utterly useless.

Doesn't even move to search for.

Unfortunately, does not work in Firefox version 73.0.

Does nothing in FF 71.0 (b12, x64)

won't work in

I installed this extension to use it in the dashboard of the ImprovMX mail forwarding service. But when I ask to replace one e-mail address (filled in many text input fields) with another, it says "No Results", however Ctrl+F finds over 400 occurrences.

Do not work
