I am running Firefox 3.6.13 on a Macbook OS 10.6.7. When the update for FF 3.6.16 became available, I began getting a pop up telling me to download it. Every time I try to do this, it keeps trying to download, but nothing happens. The message says "Downloading the update Connecting to the update server..." I am hardwired into the network at my school. What do I need to do to either get the update, or stop the pop up from happening. Interestingly, the update does not show up on the list when I go and check for software updates.
