Pandora & Firefox

[siringo]

I tried to listen to Pandora, but they say I need to upgrade my browser or install a version of Flash newer than v10.0.

This is what in the systeminfo log for Flash:
ii  flashplugin-installer                  11.2.202.336ubuntu0.12.04.1             Adobe Flash Player plugin installer

This is Firefox:
i  firefox                                27.0+build1-0ubuntu0.12.04.1            Safe and easy web browser from Mozilla

That looks OK to me. I've visited Youtube and have no problems there. Am I overlooking something??

Thanks for any help.
