Execute only on google

[pmrt]

The 'manifest.json' file has been edited so the script is only executed when browsing Google's websites. Before the changes, the extension was running on every page.

A few considerations to take into account:

Changes

The change itself consists in adding include_globs to the manifest. You can't just match all google international domains (.co.uk, .us, .es, .fr, .de, etc), so it matches everything and then it filters with include_globs to match only the google domains. See Match patterns and globs docs for reference.

Improves

Some match patterns have been changed to avoid specifying whether it is http or https. That is, instead of using two lines, e.g. "https://" and "http://", you can refer to both with the '*' character. See the official documentation here.

Note: As specified in the documentation:

If the scheme is *, then it matches either http or https, and not file, or ftp

So you don't have to worry about '*' matching other protocols.

Security

Note that *://www.google.*/* will may execute the script on scam domains like "www.google.technology" (just made up). Seeing the type of script we're working on, I don't think it really matters, but I thought it worth mentioning.

Also I restricted permissions to *://www.google.com/* instead of all domains.

Testing

At first I thought adding tests to test the feature would be great but since the only test available is a generated file —likely included with the boilerplate— I didn't want to add any e2e test without even knowing how you would scaffold it and which tools: webdrivers, test frameworks, chrome APIs, etc. would you use.

Tip: You can check if it is working looking at logs. '[bgvib] LOG START' should appear only on Google's websites.
