Mozilla has released Firefox 3.6.25 to Firefox 3.6.x users.
Firefox 3.6.25 can be downloaded from this Mozilla page.
Mozilla did not mention a great detail about this update, except the usual:
Firefox 3.6.25 fixes the following issues found in previous versions of Firefox 3.6:
* Fixed several security issues.
* Fixed several stability issues.
Which apparently only fixed one security issue where .jar was not being treated as executable in Firefox 3.6 on Mac.
