the authorizing bit is probably about payment which is likely a provider issue, do you have other paid apps?

please provide country/cell provider?

I did a search and people seem to have success with just trying again (sometimes after restarting their phone), apparently an issue with android market....

the app is tiny (currently 68k), so it should take no time to download...

I also know someone on the Mozilla team that works on the Firefox browser and for some reason that also is not available in Android Market, its just missing, since the recent update...

please also let me know what device/os version you are using.

thanks
