Has anyone automated the PywalZen mod?

[vinatic]

I want to automate the PywalZen mod. I don't want to press Ctrl+Shift+Y and then select Refresh mod styles. Instead, I want to set up an event listener for the Pywalfox extension (https://addons.mozilla.org/firefox/addon/pywalfox/) that will run the manager.rebuildMods() function when needed. Has anyone created a mod like this or knows how to do it? There is very little information available about Zen mods so I don't know how.

So you're saying that whenever PywalZen updates styles, you want it to refresh the browser styles?

If that's the case, then I'll have to see if Firefox has a file content listener.
