Greasemetal : A user script manager for Google Chrome
What is Greasemetal?
Greasemetal is a UserScripts runtime for Google Chrome. The runtime hosts UserScripts (tiny JavaScript files that modify the webpages being displayed) to be executed on Google Chrome, similar to what Greasemonkey does for Mozilla Firefox, or Greasekit does for Safari.
Greasemetal is developed by Kazuho Oku as part of his research activity at Cybozu Labs, Inc., a public software company in Japan. Greasemetal is licensed under GNU Public License version 2.
How does Greasemetal work?
Google Chrome does not provide any interface to develop browser addons. Greasemetal modifies the behavior of Google Chrome using an inter-process communication channel called AutomationProxy, which is used for automatically testing the functions of the web browser.
Using Greasemetal
- Download the Greasemetal Installer: GreasemetalInstaller.exe (1.2MB)
- After installation, launch Greasemetal from the start menu. Greasemetal will in turn start up Google Chrome, while hooking its behaviors to insert UserScripts.
- Once you have started running Greasemetal, add userscripts to the userjs directory under your My Documents folder (or Documents folder on Windows Visa). If you are unfamiliar with UserScripts, a number of scripts are available from userscripts.org.
A few limitations
Greasemetal has the below limitation and I hope this will be gone in the future versions.
- no UI for userscript management (yet)
- no support for following functions: GM_xmlHttpRequest, GM_setValue, GM_getValue, GM_registerMenuCommand

@blacknoise:
well yes, google chrome’s internal addon handling has been re designed and i think the plugin requires some changes to cope up with the new plugin handling engine which is easiliy accesible without switches.
so till a fix is released please be patient.

@ali:
Greasemetal does NOT work with new chrome versions and it will do so until the author makes it compatible
In the mean time if you want extensions to work, use Chrome developer latest which supports it. But there are limitations still
