I have a small extension (~100 users) that I forgot to upgrade until 57 landed and broke it. I hastily threw together a WebExt version and pushed on Wednesday night, but forgot to set the strict_min_version flag correctly (which was, unfortunately, Firefox 57). The new version worked fine for people on 57, but for anyone that was on ESR or a slightly out-of-date version of firefox and updated they got a broken WebExtension that I couldn't push another update to to fix it - Firefox doesn't let you "downgrade" from a WebExtension to a native extension. Thankfully a user emailed me about it and I had it fixed in less than 48 hours, but it was still a mess. All I could do was add a note to the addon description and disable the bad versions and anyone that got broke had to manually downgrade. The new Webextensions are nice, but it was definitely easy to shoot yourself in the foot with the transition. I know that NoScript also needs the same API that I was using (the ability to inspect response bodies), FWIW. The extension is https://addons.mozilla.org/en-US/firefox/addon/gpsdetect/ https://addons.mozilla.org/en-US/firefox/addon/gpsdetect/ for those curious EDIT: brevity
