Hi,
When I open google or search in address bar, before google page loads with search results, I want to add a few of my own results/links and change the color of some links returned by Google if they are present in the links I want to add.
You’d use
To run code that adds your links. Changing the colors can be achieved by injecting CSS.
Alternatively you can use an userscript extension to run js in the oage withou having to write your own extension, you’d only have to write a user script.
