After a bit of hesitation, Mozilla released Firefox 11 today. As explained in Update on Firefox Release Timing, the update was delay was initially for two reasons.
- This Tuesday is Microsoft’s scheduled monthly update to Windows, and those updates have interacted badly with our updates before. We don’t have reason to expect specific problems with this month’s updates, but we’d rather take a day or two to understand the impact before we update all of our users.
- We’re also waiting for a report from ZDI about a security vulnerability that may affect this new version of Firefox. We expect to receive the report by end of day Monday. Once we can evaluate the vulnerability, we’ll know whether we need to include a fix in Firefox before the update is released.
