Name confusion It seems to me that it would be good to make clear somehow that bootstrapped and restartless are the same things - especially as we talk about overlay legacy addons and bootstrapped legacy addons.
Tb63 - AddonManager.getAddonByID(..) used to be called asynchronously, it seems to not be called anymore?
This sounds good. I'd like to create a WebExtensions addon... but I looked at https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json
And it said that a manifest.json file is all that's required. I tried that, did a VERY basic manifest.json and zipped it and tried loading it in TB and was told it looked corrupted! Something like https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Your_first_WebExtension would be SO helpful. But I'm sure you're all too busy...
Just a point of clarity - can I write an addon and use the API that are already there... or do I have to create everything?
Tb63 - on removing XUL stringbundleset/stringbundle dies this also effect nsIStringBundleService? Or can this still be used - e.g.: let sb = Components.classes["@mozilla.org/intl/stringbundle;1"].getService(Components.interfaces.nsIStringBundleService);
