More than one site has mentioned a new point release (0.9.3) for Firefox. While this is apparently the case, the download link on the front page does not point to the setup for 0.9.3 – it points to 0.9.2. Using a little creativity, you can munge the URL for downloading 0.9.2 into one that you can use to download 0.9.3.
Update: Here’s the link that I used to download 0.9.3. The Firefox web site still has a link to 0.9.2 on their main product page. Thus far, I’ve had good luck with 0.9.3. Your mileage may vary. Please use caution.
