When I start Firefox version 30 which I just downloaded the new version, it hangs up on "Select a Country". I then have to click on the homepage icon and then it goes to my Yahoo homepage. My country of choice was previously established. I have also noticed it now works at about half the speed as the previous version. Which I believe was version 29. It also now frequently hangs up and in some cases it tells me "Firefox is no longer responding". I then have to shut it down and restart the Firefox application. I have attempted to go back to the previous version via Mozilla's webpage. But when I attempt to download it, it tells me the older version is not available to me. I am unhappy about this as I enjoyed the previous version very much with no problems.
