Is there a way to make a Chrome extension that will completely change a page html code... For example, if i load www.google.com, i don't want google's home page html loading, instead i want my own code to load. Is that possible, and can you please give me some tips on how to do that. I think i saw somewhere that this can bne "greasemonkey", or if you will "tampermonkey" for chrome. The problem is that i need to write my javascript for changing the code, and i'm not really sure how to do that.
