  1. Hi,

    I was using this because I am trying to use the juniper vpn service. I am using fedora 19 with a 64bit firefox. Juniper VPN requires a 32bit jre.

    Is it possible to have 32bit jre and firefox plugin with a 64bit firefox?

  2. Thanks very much! This really saved me a lot of time!

  3. I was not really paying much attention at first and then really just snapped in and followed this post. I’m happy, nice that I don’t have to use that junk icedtea no more. Thanks a lot :)

  4. Thank you very much, you are great. Made my task a lot more easier to complete.

  5. Thank you for help — extremely helpful, detailed, and clear! Helped me on Scientific Linux 6.
