Question

I am currently building a simple google chrome extension to prank my brother. The Extension simply deletes the old page and replaces it with HTML and CSS copied off of the \

Answer 1

Please note that most of the content in my original answer from 2016 no longer holds true.

• As of Chrome v61, content scripts are no longer allowed on the New Tab Page.

• The URL of the new tab page has changed to chrome-search://local-ntp/local-ntp.html.

• If you want to create a custom New Tab Page, use override pages.

I decided to delete the original content of this answer to avoid possibly misleading somebody. The original answer can be viewed in edit history.

Answer 2

Opened a new tab, opened the Dev Tools - Network tab. Looks like it requests https://www.google.com/_/chrome/newtab. Try with this one, maybe.

Answer 3

It's probably safer to use "exclude_globs" instead of "exclude_matches". With "exclude_matches": ["*://*/_/chrome/newtab*"] you could unintentionally skip something like http://example.com/_/chrome/newtab:

"content_scripts": [{
    "matches": ["<all_urls>"],
    "exclude_globs": ["https://www.google.*/_/chrome/newtab*"],
    "run_at": "document_end",
    "js": ["script.js"]
}],

Answer 4

According to Match Patterns, chrome is not a valid scheme.

scheme := '*' | 'http' | 'https' | 'file' | 'ftp'

1. You could use the following exclude_matches

   "exclude_matches": ["*://*/_/chrome/newtab*"]
   

2. You could also check if window.location.href contains chrome/newtab in you content scripts.
