User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36 Steps to reproduce: I had been testing Service Workers consistently on v53. However, I wanted to see if an issue I was seeing was also present on Beta and Nightly builds(using the same default profile for all). I then returned back to v53 to notice that the Service Worker was failing to register with "ServiceWorker script at http://localhost:4200/sw.js for scope http://localhost:4200/ encountered an error during installation", where it had previously been installing just fine. I was able to fix this by creating a new profile and launch v53 with that. Actual results: Service worker registration fails on v53 after testing on nightly build with same profile. Expected results: Service worker registration behaves the same on v53 before and after testing on a nightly build, without requiring the need to create a separate profile.
Sorry, realized I left off information that the failure type was TypeError.

Sorry you ran into this. It's is a known "using a profile from the future" issue. Andrew Sutherland has been noting these. Andrew, how are we tracking these?
We've haven't been entirely consistent in how we tie the effects of bug 1246615 to that bug. In many cases there have been mitigations possible so we just end up setting a dependency or a "see also". I think at this point we should just be duping every instance to bug 1246615 to better convey how many people are getting burnt by this. We can spin-off any specific mitigations to their own bugs that can "see also" bug 1246615.
