Much of the specifics of the new API are similar to the Blink extension API. Google has [https://developer.chrome.com/extensions extensive documentation on the API]. [https://dev.opera.com/extensions/ So does Opera]. But the [https://developer.mozilla.org/en-US/Add-ons/WebExtensions Firefox docs on MDN] are the best.
'''Please note:''' we are going with the name WebExtensions because it can be used in search engines, not Web Extensions (with a space) which is almost impossible to search. Information on terminology usage is available [[Add-ons/Terminology|here]].
