I'm looking to make a browser add-on as widely and easily distributable as possible.
Is there a set of wrapper addons for all the major browsers that will let me write one piece of code and it can execute in any of the environments? I don't need anything fancy, just DOM and some ajax stuff.
Something along the lines of greasemonkey for IE, FF, and Chrome would be nice.
In the same vein, is there a way to link to my script so that it prompts for an install of greasemonkey (if it isn't installed) and then leads the script?
