[Legacy] Feature Request?

[HappyHead]

Hi there! I'm one of the people using a legacy version of firefox simply because of love and appreciation for your addon.
I'm not here to ask for the addon to be updated for the new version of firefox, though that would be awesome. Instead, I'd like to ask for an added feature for the profanity filter.

As it works currently, the profanity filter scans for any words on the list and changes any word containing a listed word into whatever the user selects.
For the sake of comedic value, I'd like to request that there be an option where, instead of replacing entire words because of a component that is on the list, only that specific component gets replaced.

To explain, I set the profanity filter to replace any cuss word with "smurf" and then removed any compound cuss words from the list hoping the result would be hilarious. Alas, my dreams of seeing people call each other smurfheads or exclaim MOTHER SMURFER were dashed when I saw that that simply isnt how the filter works.

Any chance for an update to allow this silly feature to exist? Please? It'd be pretty smurfing awesome
