yes you can install two different browser!

Hi, One way would be to use the current Firefox with multiple profiles. No information is shared between the profiles and it's almost like having two Firefoxes. Please [https://support.mozilla.org/en-US/kb/Managing-profiles see this.] Another way would be to use a portable Firefox. In this case you would have two Firefoxes. http://www.portablefreeware.com/?id=132 Still another way would be to install a future Firefox. It installs side-by-side with the current Firefox. You can try Beta, Aurora or Nightly with Beta being the most stable in that order. This way you can help and be a part of the development process of Firefox and it doesn't need any other effort other than the installation. https://www.mozilla.org/en-US/firefox/channel/ ...............................................................................................................................
