Mozilla has pushed Firefox 3.6.20 to Firefox 3.6.x users. Mozilla claims Firefox 3.6.20 addresses some security issues.
Firefox 3.6.20 can be downloaded from this page.
The list of changes as per the Firefox 3.6.20 Release Notes are as follows.
Firefox 3.6.20 fixes the following issues found in previous versions of Firefox 3.6:
* Fixed several security issues.
* Fixed several stability issues

Unlike in Firefox 3.6.19, which the forced auto-update window effectivly lied to end users about the purpose of the update (removing features instead of falsely claimed security and stability), this time, the window correctly described the reason of this Firefox 3.6.20 update.
