Mozilla Firefox Editor's Review

Directly from the folks who helped bring you Netscape, Mozilla Firefox is perhaps one of the best 3rd party browsers available for Windows today.
Finding the right browser for your needs may just be a matter of installing Windows. In many cases, IE does exactly what you need; and it's an integral part of the Windows operating system. In some cases, however, IE just doesn't cut it and you need something different. That's one of the reasons why I like Mozilla Firefox. It’s a multiplatform, alternative web browser; and it runs on Windows.
Mozilla Firefox is one of the best 3rd party browsers on the market today. If you have any websites that you always open when you run your browser, you can set them up as App Tabs. Sites like Facebook, Gmail and Twitter automatically open and just a click away. App Tabs are small and can't be closed accidentally.
Organizing often used sites that you don't want opened automatically can be quickly done in Tab Groups. They are great and with Tab Groups you can visually group related tabs, switch between your groups and quickly search through all of them. To create a tab group, click the all tabs button at the far right end of the tab strip and choose Tab Groups.
When you need to find something you've seen before, all you need to do is start typing in Mozilla Firefox Awesome Bar. It remembers everywhere you've been, everything you've searched for and allows you to get to it quickly when you want to go back. The more you use it, the better it gets.

You can further customize Mozilla Firefox with Add-ons. Add-ons are like apps that you install to enhance and expand the browser. You can get add-ons that compare prices, check the weather, change Firefox look, listen to music, or even update your Facebook profile.
App Pro’s: App Tabs, Awesome Bar;
App Con’s: Personas take up memory resources more appropriately spent elsewhere;
Conclusion: If you can't or don't want to use IE, Mozilla Firefox is one of the best alternative browser choices you can make. It's fast, easy to install, easy to update and enhance and is free.
