Looked promising but does not work for discohook for whatever reason. I'm sure it works great for other websites but I can't be bothered to try when I don't need this feature for other websites.

For some reason, it works when I do it on special characters like bullet points but doesn't on normal text. I've seen it specifically not work because I'm trying to make my life easier with these mass job applications right now and end up having to go back and put it in by hand.

It only has "replace all" feature, not a selectively "replace" function. That's bad.

Works okay, but it's per-page. Have to redo this 1000 times? No thanks.

It do its work and also make a webpage totally unusable. Maybe due to 1.0.0. version, ESR won't accept anything newer.
