I mean, the browser apis are close (and Mozilla still has much better documentation) but there are a LOT of edges cases where behavior diverges. Frankly - I'm a little peeved that Optional permissions in Firefox are STILL broken - The prompt can only be triggered in response to a user action, and Firefox blows the fuck up if you put a promise anywhere in between the user click and the call to the api. Which is hugely ironic, since Mozilla is the one pushing to move all the webext APIs to be promise based (and provides a nice helpful library for Chrome/Edge/Safari support: https://github.com/mozilla/webextension-polyfill https://github.com/mozilla/webextension-polyfill) which... doesn't work on their platform. Doubly ironic, since the result is that most FF extensions just ask for more permissions up front, which is exactly the opposite of what you'd want in the "secure/private" world Mozilla claims they're pushing towards.
