All that work only to drop the addons anyway with the migration to WebExtensions. Personally, the extension I miss the most is vimperator. Mainly the fact it worked everywhere. Now you land on new tab page (or about:*) and the extension just won't load. The highlight features would be macros (automating some signin and signup workflows) and quickmarks - opens a predefined page in precisely 3 keypresses. With the way WebExtensions are right now in Firefox, a quickmarks feature just won't work sometimes, which is very irritating.
