Hi!

Mozilla put together a tool to help test Chrome web extensions for compatibility with Firefox. I took the liberty of running the Mozbar extension through this tool, and there is only one issue to be resolved before the existing Chrome extension will run on Firefox. Check it out:

https://www.extensiontest.com/test/857d5700-a855-11e7-9c3d-35e0bb5262dd

app.runtime is not supported

found in the following locations:
        scripts/browser_button.js:46697
        scripts/content_page.js:60933

Just a couple changes and this will work on Firefox! Any chance we'll see it soon?

Near as I can tell, the biggest technical blocker to porting the Chrome WebExtension to Firefox will disappear in Firefox 53[0], which lands in the general release channel on 2017-04-18[1]. In other words, now is a good time to start porting, since it can be tested in nightly today.
