&gt; <i>How long until the next extension API that will get it right This Time?</i><p>WebExtensions are likely to be The One True API. Chrome, Opera, Edge, and Firefox all support them, and we&#x27;re all working on standardizing them at the W3C: <a href="https:&#x2F;&#x2F;www.w3.org&#x2F;community&#x2F;browserext&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.w3.org&#x2F;community&#x2F;browserext&#x2F;</a><p>&gt; <i>If I wanted handicapped extension APIs, I&#x27;d just use Chrome.</i><p>Though we&#x27;re trying to avoid reinventing wheels, we&#x27;re not limiting ourselves to Chrome&#x27;s APIs. For example, <a href="https:&#x2F;&#x2F;bugzil.la&#x2F;1242871" rel="nofollow">https:&#x2F;&#x2F;bugzil.la&#x2F;1242871</a> extends Chrome&#x27;s webRequest API to provide additional metadata needed by the NoScript and RequestPolicy add-ons. The initial development <i>is</i> focused on Chrome parity, since that covers most add-ons, but once we get there you&#x27;ll see more of an emphasis on landing APIs that are needed by existing, more powerful Firefox add-ons.<p>If you&#x27;re an add-on developer yourself and are concerned about APIs you need, please fill out this survey so we have a record of it: <a href="https:&#x2F;&#x2F;docs.google.com&#x2F;a&#x2F;mozilla.com&#x2F;forms&#x2F;d&#x2F;1PtRXcs9UHVMjge77b2QHpvUE4Xpz7erbTAOTYdt5q5k&#x2F;viewform" rel="nofollow">https:&#x2F;&#x2F;docs.google.com&#x2F;a&#x2F;mozilla.com&#x2F;forms&#x2F;d&#x2F;1PtRXcs9UHVMjg...</a>
