With the old firefox, one could force an update by clicking 'firefox' on the menu bar and then 'About firefox' etc. However, with the new firefox 38 this menu only contains the single entry 'Quit' -- there is no 'About firefox' or anything else.
So how can I force an update of firefox? (OS X 10.9.5).
When I go to firefox->menu->preferences->advanced->update->show update history, it says that 38.0.1 was successfully installed, but that 38.0.5 is 'pending'. How can I advance that state from 'pending' to 'successfully installed'?
