Sometimes useful, but it doesn't always work and it breaks Tumblr for some reason.

It did what it was supposed to, but somehow it broke every rich text editor and several other text input fields on various websites so I had to uninstall it. Well, I'll survive.

Simple interface makes it very easy and approachable to use. The text is a bit too large for my taste (and I'm usually one for large text). It would also be nice if the entries could be alphabetized, but it works well all the same.

UPDATE: Sadly, after a few days use, I found that not all instances of the words are replaced. It seems if the text isn't part of the main page and is instead dynamically loaded or within a frame, it's ignored. That is no optimal. Sorry.
