Utilu Mozilla Firefox Collection is a software package that contains multiple versions of the Firefox browser. It is designed for web designers and developers that want you check the way a website is rendered in a different Mozilla Firefox edition.
A user can try to install all these versions individually but it can take a lot of time to download and to run each installer. In addition, all the versions come with preinstalled web development tools that enable you to analyze the webpage. Adding these plug-ins to every installation takes a lot of time that can be saved by using this collection.
The main web development tools are provided by the Web Developer and the Firebug plug-ins that are included in every browser. You can also customize the installation of a specific version by adding plug-ins or by changing the settings without affecting the other Firefox versions.
The installer of the program allows you to select the versions that you need to install. You can use them separately or even at the same time without any issues. The application provides you with an automatic tool that opens a certain URL with all the installed versions in order to compare the result.
You can use this tool to open multiple browser tabs by entering more than one URL. It is a time saver for the users that need to compare multiple websites in their daily activity. However, if your installation includes all the Firefox versions, it can take some time to open all the browser windows.
If you developed a web application or a website that needs to be tested, you can try the Utilu Mozilla Firefox Collection. A single download can bring you more than fifteen versions of Firefox to choose from.
