After upgrading to Firefox 30, I have been facing a lot of irregularities in Mozilla Firefox 30.0
After upgrading to Firefox 30, on the Mozilla Firefox site it says that my browser is out-of-date. Gmail attachment button at 'Compose Mail' isn't working. The Google search look-and-feel is that of when it was a few years before . Many add-ons such as 'Goal sidebar' for the FIFA WC 14 says that it's not compatible with the browser .
Firefox 29 seemed to work fine but not this!
