Happy to see that Mozilla was serious about their intentions to extend the WebExtensions API in post-57 Firefox. I'm also happily surprised at the section about user notification of extension overrides; having a nice UI for this sort of thing is a difficult yet worthwhile problem (and I'm also a big fan of the new Preferences tab in general, it works far better than the old popup window). Hopefully some of this will…
It's funny that vimperator is mentioned every single time Firefox extensions are brought up on HN even though it only has about 11,000 users out of the hundreds of millions that use Firefox.
And, ideally, we should see extensions upturning the interaction model as users experiment with alternatives; that this is no longer possible, that the fundamental model is defined and hardcoded (with minor flavour differences), is, I think, a significant loss.
Its a shame there are few extensions like vimperator; its a greater shame there are none.
