One common use-case is to use it to handle some cache and allow a page to work even if the network is slow, unreliable or disconnected. Firefox is not the only browser to implement it, as it's already available on Chrome : http://caniuse.com/#feat=serviceworkers [1] If it's disabled for ESR, this feature will simply be unavailable for websites. So they will work as they do now (unless, of course, some bad javascript coder decided to write things like "if the HTTP agent says that Firefox>=44" instead of "if serviceworkers are available on this browser"). As Service Workers are not widely available for now (except in Chrome), and will not be available everywhere for a while (see Microsoft browsers), I think the websites need to handle this properly (i.e. test the availability of the API, and use a fallback method if unavailable). So I don't think there is a big risk. Even if I'm disappointed that we won't have this API for 45 ESR, I understand the reasons Mozilla gives : it's certainly better this way.
