I'm A Ubuntu 13.04 User , Everything Was good but software updater told me that there are new updates so I'm Installed All of the Updates (including Firefox) but after this update ,my Firefox goes so slowly & Hangs up in seconds ! Can I down date!(opposite of update!) My Firefox ? if OK How ? I have a Nightly (A 64-bit Beta version of Firefox) in Windows 7, I'm using that for a long time & I Think That was & is GREAT ,Can I install Nightly in Ubuntu 13.04 ? Again if OK How ? (sorry for my bad English)Thanks!
