While Mozilla offers up to $500 for bug reports,
Google will offer a base reward of $500 to anyone who submits an eligible bug. If a user finds a severe or clever bug, Google will pay up $1337 (surely appealing to all of our inner geeks) to the developer who discovers it.
Flaws must be submitted through the Chromium bug tracker, and all submissions will be considered by a panel of engineers. That includes bugs in Chromium, Chrome and plug-ins such as Google Gears.
