Your memory of desktop Chrome doesn't match mine. Chrome added extensions more than a year after launch. http://chrome.blogspot.com/2009/12/google-chrome-for-holiday...

Its extension model remains superior to Firefox's, and I hope Mozilla fixes this. I shouldn't need Python and an SDK installed to develop a JavaScript browser extension. https://developer.mozilla.org/en-US/Add-ons/SDK/Tutorials/In...

I read bad_user's comment as saying "desktop Chrome supported extensions from the start, but mobile Chrome doesn't; so I switched to mobile Firefox for the extensions, and then subsequently to desktop Firefox for Sync."

You don't. The only things you need are a text editor and a zip utility (and I'm not sure about the last; it's certainly not needed if you're not distributing the extension). You only need the SDK if you want to use the Add-on SDK.

Then it's a problem with the documentation (https://blog.mozilla.org/addons/2014/06/05/how-to-develop-fi...), which is a little easier to fix.
