GreaseMokey (Chinese call it Oil Monkey script) was previously just a plug-in of Firefox, which can be used to add some simple and useful plug-ins to expand the functions and experience of your browser. It is generally written in HTML + JavaScript, and has the characteristics of smallness and flexibility.
A very good news is that the latest version of Chrome 4.0 now supports GreaseMonkey scripts , and of course, Chrome 5.0 dev version also supports it. If you are using these two versions of Chrome (including PC and Mac), you can immediately access http://userscripts.org to get more than 40,000 scripts.
If you don't know much about GreaseMonkey, you can check out the introduction of wiki encyclopedia, or check out the "8 Excellent Grease Monkey Script Recommendations" and Crazy Software's Top Ten Oil Monkey Script Recommendations. Of course, there are many excellent GreaseMonkey scripts. If you encounter a more useful script, you must share it with us~~
In addition, GreaseMonkey's management is as convenient as ordinary Chrome extensions, and can be disabled and uninstalled in Chrome's extension panel (chrome://extensions/).
