If you want to use the old type of extension/addon, try these..
"Pale Moon is based on a derivative of the Gecko rendering engine (Goanna) and builds on a hard fork of the Mozilla code (mozilla-central) called UXP, a XUL-focused platform that provides the underpinnings of several XUL applications including Pale Moon. This means that the core rendering functions for Pale Moon and Firefox (and rebuilds) will be a relatively close match and that functionality in the Gecko core code"

"Basilisk is a free and Open Source XUL-based web browser, featuring the well-known Firefox-style interface and operation. It is based on the Goanna layout and rendering engine (a fork of Gecko) and builds on the Unified XUL Platform (UXP), which in turn is a fork of the Mozilla code base without Servo or Rust."
