Customize the appearance and behavior of popular websites
Greasemonkey allows you to customize the way popular websites look and behave by tweaking their functionality with a script.
In fact Greasemonkey is not an application in itself. It’s a Firefox add-on that prepares your browser to support Greasemonkey scripts. The add-on puts a small monkey icon in the bottom right corner, from where you can add new scripts and manage the ones you’ve already installed. Other than that, it doesn’t include any configuration options.
The first time you launch Greasemonkey you’re presented with an introductory website which contains basic information and a link to Userscripts, where you can download scripts. Be sure to bookmark this site, as Greasemonkey doesn’t include a link to it anywhere.
Of course, you can also create your own scripts and use them with Greasemonkey – but that requires coding knowledge.
With Greasemonkey you can use hundreds of scripts to change the way popular websites look and behave.
Changes
Enhancements: Script updates install automatically. (#1442) In 0.9.12 we added update checking. In 0.9.13 updates install automatically, but there's still some discussion over how to handle this best (#1455), so checking is still not enabled by default. We hope to figure this out by the 0.9.14 release. Some other update related work was done, mostly to make Firefox 3 work better. (#1421, #1422, #1423) Provide an Options item in the Monkey Menu. (#1447) Add a Cancel button to the Options window. (#1454) Bug fixes: GM_getResourceText() was broken. (#1438) You can properly select an application (bundle) for the editor on Mac OS X. (#1439) Fix GM_openInTab() for Firefox 3. (#1444) Fix when pages reassign the location during page load. (#1445)
