In response to a denial of service vulnerability that was detected in Firefox (which allowed a hijacker to crash Firefox by trying to use a deleted controller context with the designMode option turned on), Mozilla released Firefox 1.5.0.3 on May 2, 2006. Mozilla recommends that users update to this version (can be done automatically with Firefox 1.5.0.2) and users can access the release notes for more information. Download links for each of the platforms have also been provided.
