Tuesday saw another stealth release of Firefox: version 26. As usual, the new version was not announced by Mozilla; I learned about it from a post on the CERT Current Activity blog. The official release notes for version 26 describe some of the changes in this version: nothing worthy of note. Version 26 does include fixes for some security issues, so you should upgrade as soon as possible.

Update 2013Dec16: One notable change in Firefox 26 is that Java is now blocked on all sites by default. This behaviour can be changed, but we recommend using the default setting.
