Viewpad 7 processor is an ARMv6 which is not compatible with Firefox for mobile.

For more information, see System requirements for Android.

If you're adventurous there is the experimental nightly builds for ARM6. There's no guarantee anything will work though.

Yeah the ViewSonic Viewpad7" is using the newer ARM11, well to be more accurate the ARMv6ZK ARM1136J(F)-S (Qualcomm MSM7227). http://en.wikipedia.org/wiki/ARM_architecture#ARM_cores

The Nvidia Tegra 2 that some tablets are coming with for example is a dual Cortex-A9 which is well a ARMv7.

I know for sure the 10" gTablet is using the 1GHz NVIDIA Tegra 2 - Dual-core ARM Cortex-A9. Not sure about the 7" but this 10" is actually a rebranded malata SMB-A1011. Their 4.3" VPD400 PMP is actually a rebranded older Ainol V6000 model.

For more than 1 year we are waiting for the support of the ARM6. And you still work on it. How long will we wait again ? The new beta version is launched, with this damned flash support we never had before, but for US the ARMv6 possessors, still nothing ! Thanks to think about us........
