IntelliJ Firefox Web Extensions Development

Question

Am learning how to use the Firefox Web Extensions API, and am using IntelliJ.

Is there a way to get code completion / suggestions for the API?

I followed the steps in the answer below, but there doesn't seem to be a complete one for Firefox.

Answer 1

Firefox WebExtension type stubs were added recently (Nov 2017) under the name firefox-webext-browser. The steps in the answer you linked are now valid (relevant changes in bold):

First time setup

1. Open the Settings dialog (File > Settings)
2. Click Languages & Frameworks > Javascript > Libraries
3. Click Download
4. Make sure TypeScript community stubs is selected
5. Select firefox-webext-browser from the list (you can find it quickly by just typing firefox-w)
6. Click Download and Install
7. Click OK to close the Settings dialog.

In Subsequent Projects

1. Open the Settings dialog again (File > Settings)
2. Click Languages & Frameworks > Javascript > Libraries again
3. Check @types/firefox-webext-browser
4. Click OK to close the dialog.
