Firefox 6 and Thunderbird 6 were released on August 16, 2011. This version was released on August 30, 2011. In this time, a critical issue was fixed.
- Revoked the root certificate for DigNotar due to fraudulent SSL certificate issuance (witten by Firefox 6.0.1 Release Notes and Thunderbird 6.0.1 Release Notes)
If SSL certificate is abused, the authenticity of sites handling private information, such as an online shopping site and a password locked site, will become impaired. Well, Firefox 6.0.1 will be automatically updated by Firefox 6.0.
Concretely, if your comparatively new web browser accesses to an unproved site by public SSL certificate in the Internet, the browser will display warning message. Then, Internet users will be able to use the information for safety judgement.
