typically to match content_scripts
everywhere we set like this:
"content_scripts": {
"matches": ["http://*","http://*"],
}
or
"content_scripts": {
"matches": ["<all_urls>"],
}
but they don't include pages like chrome://extensions
or chrome://settings
Apparently it accepts
"matches": [
"*://extensions/*"
],
or
"matches": [
"*://*/*"
],
as well but that isn't a match for the extensions tab.
This is not working anymore so please reopen.
