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.

It would be nice to make it replace "No Man" with "Gnome Ann" as in 1704

Does what it says in the tin, great!

Does exactly what it's supposed to do. Love it. Thanks. "A uncontrollably swerving cat owned by Apple was involved in an accident, California’s road authority has confirmed."

Substitutions 2 is 1625, not 1265. But otherwise great, exactly what I was looking for!

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.
