  1. I’m using RHEL-6.4 and i don’t have RHN subscription.

    • You need RHN subscription to install needed dependencies on RHEL 6.

  2. Hi, why firefox 27 is not in remi repository?

    • Hi George,

      I’m not sure, but I guess that it’s coming soon.

  3. Worked from the first time! Thanks!

  4. Not so soon, because this version is released on 4-feb-2014 now is 11-mar-2014. After week or two they will release firefox 28.

    • Hi again George,

      Just checked Remi’s forum and I found that the reason is the lack of time. So maybe next build is Firefox 28 then.
