The script wasn't working before the latest update (for a few days) due to an update to a third-party script it uses.
I don't see how the latest update specifically would have broken the script. Still, it's very possible it doesn't work with other script managers besides Tampermonkey in general, because it uses some GM_ functions that the script manager provides. It's possible Violentmonkey doesn't provide those same functions...
I don't generally support other script managers, but I might look into this later if I have time...
Latest version broke VioletMomkey on either Firefox or Chrome. Tampermonkey works well.
