Starting User script in Greasemonkey
Is it possible to run a user script before the page and DOM lo开发者_开发问答ads?
Only if the user script runs on google chrome atm. Greasemonkey may support this too someday:
// ==UserScript==
// @name My script
// @description It's really neat
// @run-at document-start
// ==/UserScript==
As Erik Vold said, Greasemonkey cannot do this unless the browser is Chrome.
But, if this functionality is needed on any other browser, you can write an extension.
