Many sites like “Elude” work perfectly without javascript, that is, without compromising the privacy and security of their users and allowing their use through tools to escape censorship such as Tor.
This is a necessity to allay doubts about Lemmygrad being a honeypot.
Tor browser uses LTS firefox, is sometimes late with updates for bugs that don’t seem critical and is mostly the same on every OS, platform pair. Disabling javascript makes successfully exploiting any existing bugs many magnitudes harder. (which is already quite hard tbh)
