Won't start after update to 3.6.6 Mac OSX 10.6.4

Have updated to 3.6.6. on OSX 10.6.4. Installed as per instructions, but FF does not start - from the application folder or the dock (to where I dragged the FF icon). From looking at the support forum there seems to a number of people experiencing the same problem, but no fixes appear to be posted!

Solved by going back to 3.5.10. All settings and bookmarks came back. Won't be upgrading again anytime soon - or will be switching to Chrome!
