Dave Hyatt and Blake Ross created the project Moilla Firefox. It was done as an experiment in that branch. You have different versions in Firefox, like version1.0, version1.5, version2.0, version3.0 and version3.5. The Firefox retains the original cross-platform of the Mozilla browser. It retains the cross-platform using the XUL user interface markup language. Due to the XUL it is possible to extend the browser’s capacity through the use of extensions and themes.
Mozilla Firefox has Adblock. Adblock is a content filter extension. This Adblock is for Mozilla Firefox and Mozila application Suite based web browsers.

An improved version of the Adblock of Mozilla Firefox is Adblock Plus. Adblock Plus has grown to replace the old Adblock.
