Now that Firefox 0.9.1 is out, it also means new Themes and new Extensions. That, and all the cool features are just a few reasons why you should definitly:

I absolutely love that you can use themes. I have my favourite themes from Mozthemes.

There are an aweful lot of awesome extensions you can install on your Firefox. Here are my favourites:

Allow Right-Click 0.1
Defeats web sites’ right-click prevention scripts.

CuteMenus
Iconifies your menus and popups.

GMailCompose
Adds a GMail Compose link to the context menu for mailto: links and text addresses

Googlebar
The Googlebar for Firefox

IE View
Adds “View page in Internet Explorer” links to the content and link context menu. Handy for previewing pages in IE, loading up IE-only pages when you run across them in Mozilla, etc.

What are you waiting for? Get your own Firefox now, and customize it to your liking!
