Yes, strict tracking will still block extensions. I hate the way permissions work with Fraidycat - I shouldn't need access to your website data to do this, for instance - I just need the ability to access URLs without using your credentials. Unfortunately there doesn't seem to be a permission for that. (Admittedly, I doubt they had something like Fraidycat in mind when designing the web extension API.)
