Manifest: Error processing update_url

[jaller94]

Browser: Firefox Nightly 62
Extension: 2018.5.10

On the page about:debugging#addons I get the following error:

Where does update_url come from? It’s not documented on MDN.

Why does it point to a Google URL? For a privacy-focused extension this seems suspicious.

privacybadger/src/manifest.json

Line 117 in 7aa109e

"update_url": "https://clients2.google.com/service/update2/crx"

This is because we use the same manifest for Chrome and Firefox. There is no actual problem, just a visual nit. Firefox could just ignore Chrome-specific fields.

See 0851983 and https://crbug.com/805755 for the gory details of why we need "update_url" in the manifest.
