As an FYI, this appears to be occurring on other extension builders' sites as well. For example, https://noscript.net/

This looks like bug 1356292 but using InstallTrigger instead of a direct link.  And, it looks like the patch for 1356292 covers InstallTrigger as well, excellent.
I verified this manually -- on a Nightly build from yesterday, the "Install now..." button yields the "Firefox prevented this site..." notification, on a recent build (a local build, I didn't check if this made today's downloadable build), we get the same dialog but with Allow/Don't Allow buttons, which is the intended behavior for InstallTrigger.
