Web Extensions vs Xul

1. look at what's possible to implement using WebExtensions
2. look back at some of my XUL add-ons
3. cry in total despair.

1/3 let's be clear, WebExtensions are messy, hyper-limited and a DEEP regression compared to the power of XUL.

2/3 WebExtensions will need *years* to reach even the minimal level for the simplest XUL-based add-on.

3/3 betting on WebExtensions *now* is harmful to the add-on ecosystem of Firefox; and since it's one of the great attractors to Firefox..
