We're thinking of switching to webdriver

This page is based on the mozwebqa email conversation: selenium 2 + WebQA

Reasons to switch to webdriver:

• selenium does not support hover, but the addons impala redesign will be making heavy usage of hover
• selenium does not support mobile testing, webdriver does

Reasons why we've held back from switching to webdriver:

• grid performance issues (now resolved...enough)
• we use sizzle locators and will have to switch these to xpath before we can change our api
• no support for native events on mac (key presses, click, etc.)
