I am trying to code a chrome extension where the ultimate goal is to have numbers here:

Green highlighting is where numbers go

It is for the shown page only.

To get in and change those though I need to access the site first of all. What is the match permission for this url? I am using v2 currently and have tried this:

"content_script": [{
   "matches": ["https://www.google.com/search?q=*"],
}]

Which I thought would work.

(Not entirely sure if that the right URL but I think it is) (Also know that that is from v2 but I am not sure if that's how you do it in v3 which would be ideal - the docs aren't very clear - do you use hosting_permissions?)

When I tried that it came up with the message 'These extensions don't need to see and change information on this site'

Does anyone know how to do this in manifest v3? Essentially I want to acces the html of a google page and change it.

  • You need to declare `js` files there, see the documentation, but there's a much more efficient method: hide these elements via `css` [content script](https://developer.chrome.com/extensions/content_scripts) and specify `document_start`. – wOxxOm Feb 10 '22 at 14:26
