• Navigate to https://testsafebrowsing.appspot.com/ and verify that you see appropriate warnings for different demo pages

--
The dev safe browsing key is limited to 2000 requests per day. Reach out to google to get an updated key with increased request quota per day. cc: @flamsmark

Generated the key.
Will be double checking the proxy is working on Monday.
will work with team to make sure the key is used in future CI builds for all channels.

Note: If using environment variables look for the npm_config_brave_google_api_key and npm_config_brave_google_api_endpoint environment variables as examples of how this works in the Jenkins build jobs currently.

The new key has been generated, we have upgraded the quota for the key as well. @mbacchi and @RyanJarv are working on setting up key in the proxy. Issue tracked here: https://github.com/brave/devops/issues/208
