Firefox for Android is evolving quickly and we need all the bugs we can get!
We really need Mozillians to help test various builds of our mobile browser and file bugs to continue to make the product better. We're looking for a diverse group of Mozillians, that means everybody - contributors, localization, marketing, accounting, HR, engineering, etc. Your participation matters (and there will be swag/prizes for our Testdriver-superstars).
Don't think you're technical enough to help? Think again. We have docs to help you install, update, test, and file a bug when Firefox is crashing, hanging, slow, or has other issues, see https://wiki.mozilla.org/Mobile/Testdrivers_Program/How_To
If you are interested in helping to create the best mobile Web browser the world has seen, please let us know so we can provide next steps and more information.
