Firefox question

[Shamrock]

A while back, someone referred me to the command to make Firefox NOT display the green underlined text. I now cant find it, what is the command? I know you have to goto about:config (it references different words in a webpage)

I had my Firefox profile deleted, and now I cant remember where it was I found it.

Thanks

I just use adblock and block intellitxt (or something similar).
