You’re right, Unhook does look abandoned.
Sorry, I initially mixed it up Unhook with UnTrap [1] because of the similar name. UnTrap's Chrome version seems maintained (February 2026 [2]), while the Firefox version seems abandoned too (December 2024 [3]).
One of my goals with Maxxmod is to avoid that abandonment pattern.
