Per bug 590608, Personas 1.6 causes a bad interaction with certain add-ons (including the Google Toolbar). This interaction is so bad, it breaks the extension manager. What that means is that when the Personas team fixes the problem, people that actually have the problem will not get the update. It also means that the add-on cannot be blocklisted. Over a million people received the Personas 1.6 update. Special code needs to be added into Firefox 3.6.10 to block Personas 1.6 so we don't leave up to a million people stranded with a broken extensions manager and no way to fix it.
I'm not sure whether this is necessary since we can use the blocklist service to block personas 1.6 or we can probably also solve the problem by fixing bug 595092
The update bustage _also_ broken updating the blocklist. But, the 3.6.10 update does indeed fix this bug via a dupe
