Question

I want to replace all the text on the page, for example: all “Hello” to “Hi”

I’m currently using

body.innerHTML = body.innerHTML.replace("Hello", "Hi");

I’ve been running into two problems:

1. there might be Classes or IDs named Hello (e.g. <div id="Hello"></div>, then it would mess up this code)
2. For some reason Gmail breaks when I try to replace the body

Because this is Chrome-specific and you don’t have to worry about legacy browsers (cough IE), this sounds like a job for a treeWalker. There’s a decent example of how to use it here.
