WebMonkey

WebMonkey is a no-frills light-weight web browser with support for Greasemonkey user scripts. It uses the WebView GM library to enhance the native Android System WebView with support for Greasemonkey functions and the management of user scripts.

Caveats:

• userscripts only run in the top window
• they are not loaded into iframes

Note that „no-frills“ can also be interpreted as „bare-bones“. If you’re looking for a polished GUI with bells and whistles, this is not for you…
