Mozilla Firefox is one of the four leading web-browsers, the other three being MS Internet Explorer, Google Chrome and Opera. The battle between them has been raging for years and seems to have no end. Firefox's weapons have always been its security and the huge number of various add-ons written by the users community. Since Firefox is open-source software, everybody who feels they have a streak of web design in them can try and create their own add-on or app customizing their browsing experience.
The release of Firefox 5 seems to be Mozilla's another attempt to score off its rivals by introducing some new features into the browser.
At a glimpse, there are not that many changes in Version 5.0.1 as compared to previous Firefox releases. However, if you take a look at the changelog on the developer's website, you may see that there are quite a lot of them, but they are mostly internal and affect the browser's machinery rather than interface. So, the log shows Mozilla patched some serious vulnerabilities, five of which were rated as critical by Mozilla, and fixed about a thousand bugs.
The major tangible new feature is the “Do not track” option made more accessible. Now it can be found under the “Privacy” option. Just tick the checkbox and you won't be tracked by websites any longer. This feature makes Firefox 5 the browser of choice for security-conscious users or the people who are tired of the annoying lack of privacy on the Internet. The “Do Not Track” option is also available on Android (Google's operating system for mobiles and tablets), which makes Firefox the first browser to support this feature on multiple platforms.
In short, Firefox 5 is a nice web-browser, focusing on the secure browsing experience. Even if you are a dedicated Chrome or IE user, Firefox 5 is worth giving it a chance.
