Welcome to the world of freedom and the blessings of an initiate source browser. Unlike Microsoft's heavily integrated Internet Explorer, Mozilla's Firefox has the advantage that it is under continuous development and therefore is a lot less likely to have security loop holes, such as the ones so commonly exploited in Internet Explorer which scour its already blemished reputation.
The layout of Firefox is remarkably similar to that of Microsoft's, as any web-browser should discover, with the standard address bar and other features in the expected places. However, apart from the exterior looking similar, there are some major differences and notable improvements included in Firefox. The first of which is tabbed browsing. This makes a massive inequity for frequent internet users, and means that only one window can be initiate, but many websites available at the switch of a tab. This means that the task-bar need no longer be cluttered with many different windows.
The "Download Manager" of Firefox is also a broad improvement on Internet Explorer's misfortune. As well as allowing you to do a approved folder to download all files and folders to, it also lets you cease and resume downloads at any point, meaning those longer downloads can be saved in chunks and means that you don't have to leave your computer running until the download is completed.
The "Favourites" menu has also improved on Microsoft's system, with pages being tracked, and then notifying you if their situation changes at any point. In practice, many sites are loaded identically to what they would examine like in Internet Explorer, and the major increases security means that Mozilla's Firefox web-browser, will be a noble, regain, and posthaste application for all internet users.
