I need to have FireFox 3.6 and (any) modern version installed at the same time. How?

Posted

Hi. As per the topic. The nature of my job (test analyst) requires me to have both the old 3.6 and any of the modern versions of FF installed on my PC. Is this possible at all and how can I do it? Many thanks.

You can install the portable Firefox 3.6.x version to access websites that do not work with Firefox 5+.
