Installation

Chrome

Just download the toolbar directly from the Google Chrome Webstore

Safari

In Safari (I tried OSX 10.6 and 10.8) one easy way is to use NinjaKit which is an extension that lets you install user scripts. The usage is straight forward: First you download the file NinjaKit.safariextz and install it by double-click. After that you should see a ninja-star-like button in Safari

where you can manage your user scripts. If you now click on the above link to m_toolbar.user.js, you should see a pop-up like this

and a click on Install finishes everything up. Another click on the ninja star button shows you now the installed Mathematica script
