For long the extension I maintain, uBlock Origin, was not listed at https://www.arewee10syet.com/, but today I found out it had been added to the list, and marked as a "shimmed"exyension – with no issue number provided.
I am not aware of uBlock Origin not being fully compatible with multiprocess – given it was first written for Chromium, being fully e10s-compatible was built-in from the start.
How can I find out why it is marked as “shimmed”, so that I can address whatever it is that prevents it from being marked as a fully e10s-compatible add-on?
