Firefox 4 Beta 1 was released yesterday. I ran the browser through some tests and did a review of Firefox 4 beta too. However, if you are a bit scared of installing the browser on your system, you might try it out as a portable software. The good part about using it as a portable software is that it won’t change your system settings or add data to the registry and you can safely delete the browser if you are not happy with it.
You can download Firefox 4 as a portable software and then unzip the contents to any folder to run it. To delete the browser from your system, you will just have to delete the unzipped folder. Nothing gets easier than that. Excited to try the Firefox 4 beta on your system? Check for the download links below.
Please note, Firefox 4 is still in beta, so there will be a lot of bugs. If you are not comfortable with unfinished software you are recommended to stay away from using Firefox 4 Beta.
