I have installed Waterfox - the 64 bits version of Firefox. I am on Windows 7 64 bits machine and have Waterfox and Firefox as well. The issue is, when one of the browsers is opened, and I clicked on the other one, a new windows is opened with the already opened browser - I am not able to open the two browsers at the same time.

Has anyone knew the reason and how to fix it?

According to Waterfox website:

Waterfox shares the same profile data that Firefox does.

Thus, what you want to do is starting a new instance of Waterfox (or Firefox), or create a different profile. Please take a look at this for information on how to do that using -no-remote and -P options.
