Question

I am making a content script that does something with the google results webpage.

The line below in the manifest.json is not valid.

“matches”: [ “https://www.google.*/*” ]

The error due to above line in manifest.json is:

Invalid value for ‘content_scripts[0].matches[0]’: Invalid host wildcard.

I want to run the script on various domains like google.com, google.co.in, google.de etc. How do I accomplish that?

Answer 1

Wildcards are not allowed in the TLD of a match pattern.

Google has published a list of supported domains. Each domain is put on a separate line, and looks like .google.com. You can use this list to produce a valid match pattern, such as (I’ve used www as a subdomain, for the example):

"matches": [
    "http://www.google.com/*", "https://www.google.com/*",
    "http://www.google.ad/*", "https://www.google.ad/*",

Instead of http:// and https://, *:// can be used. Note that more search portals exists:

• https://encrypted.google.com/ -> "https://encrypted.google.com/*"
• https://ipv6.google.com/ -> "https://ipv6.google.com/*"
• Specific search engines, such as maps, news.
