For many of us who constantly struggle with using Internet Explorer while conducting day to day web surfing and what not; Mozilla Firefox provides a refreshing and attractive new alternative.  After experiencing numerous issues with IE; including slow performance, interrupted connections, virus and Trojan infections etc. running Firefox is an absolute delight.  While I had heard before that Firefox provided more security and faster web surfing capacity I never really got around to installing it on my device.  However, that all changed when a couple of months ago I kept getting attacked by viruses and Trojans despite having so call protection with Norton Antivirus.  I went through the regular cleaning of cookies and temporary files and ran Microsoft Baseliner , all to no avail.  I finally got fed up and decided to take a look at Firefox, and boy I’m I glad that I did this.  Now, I use solely Firefox when surfing the net and have ran into zero problems.  The speed/ performance is great and I never have interrupted connections.   Also with Firefox's "private browsing" feature, you can limit who gets to see your browsing history and protect your privacy.

Mozilla Firefox is a free and open source web browser descended from the Mozilla Application Suite and managed by Mozilla Corporation. As of February 2011, Firefox is the second most widely used browser with approximately 30% of worldwide usage share of web browsers.[9][10][11] To display web pages, Firefox uses the Gecko layout engine, which implements most current web standards in addition to several features that are intended to anticipate likely additions to the standards.[14]  Source:
