If you are a Lifehacker reader you probably noticed that they have released Better Gmail 2 Firefox extension version 0.3.5. However until it is fixed you have to install it in another way than just clicking on the download button.

1. Clear Firefox’s cache.
2. Right-click the download button and choose save as and save it in ie your documents.
3. When downloaded, drag the file to an open Firefox window and the installation will start, just follow the steps and you are done.

Better Gmail 2 is a must for all Firefox users
