Mozilla Firefox 3 3.6.28

Firefox 3 is a browser with very good features and a great history that is currently somewhat outdated but still operational today.

This browser is only recommended, for now, on older computers as it will allow you to maintain a good browsing rate, has good security controls and allows browsing in hidden mode, which leaves no trace on your computer or Internet history.

Keep in mind that today's browsers have many tools and utilities that ultimately make your computer consume more resources. Therefore, if you have an old computer you don't have to be ashamed and use a higher version, because it works great.

Also, this version of Firefox is not recommended for modern computers compatible with Html5 because the browser does not support it and would be unable to display certain pages.
