I heard about being able to have the internet and all it offers at your finger tips.
hello, i think the optimus zip has a screen resolution too low & not enough memory to run firefox unfortunately - it isn't listed as a supported device either: https://www.mozilla.org/firefox/mobile/platforms/
Yeah, the Optimus Zip is an entry-level device and I suspect it won't work. That said, if you see it listed in Google Play, feel free to try it out!
If you are willing to try a development build you can install the Android ARMv6 version at http://nightly.mozilla.org
