I second that the substitution shouldn't work in the middle of words.
Just another nitpick but it'd be nice to check for the lang attribute to ignore non-English pages.
Anyway, thanks for making the news wackier!

Amazing add on, but I'd much rather it only replace the trigger words by themselves, not other words that have the trigger words in them. For example, Apollo changes to Apsychic readingo; I'd rather it change poll to psychic reading only when the word poll is by itself.

Seeing CNN write "Just as the DMV can revoke a human's license, it can also revoke a company's ability to operate uncontrollably swerving cats on state roads, under the proposed rules." makes news reading a whole lot more fun. Thank you for bringing it to Firefox.
