Mozilla released Firefox 10 today, including a major update that will make both developers as well as Firefox users happy -- default compatibility of almost all add-ons.
Although default compatibility of add-ons will make a lot of people happy, this change is "prioritized as a P1 and part of achieving 'silent update'." as indicated in the feature tracking entry of "Add-ons Default to Compatible" in Mozilla Wiki.
Security Update
"Title: Frame scripts calling into untrusted objects bypass security checks
Impact: Critical
Announced: January 31, 2012
Products: Firefox, Thunderbird, SeaMonkey
Fixed in: Firefox 10.0, Thunderbird 10.0, SeaMonkey 2.7
Description: Mozilla security researcher moz_bug_r_a4 reported that frame scripts bypass XPConnect security checks when calling untrusted objects. This allows for cross-site scripting (XSS) attacks through web pages and Firefox extensions. The fix enables the Script Security Manager (SSM) to force security checks on all frame scripts."
