When I launch Firefox from the Applications Menu, there always appears a 2nd button on the Window List bar saying "Starting Firefox Web Browser". It stays there for about 15 seconds. And the mouse pointer is busy during this time.
This gives me the impression that Firefox starts very slow on Fedora. (F9 and F10).
Just now I discovered that if create a new launcher and remove the %u option from the command, Firefox starts up immediately!
Why is the %u launcher option causing this poor user experience?

Not at all. Firefox is always slow to start, no matter what command line options you specify :) One thing you can do to speed up a little its start up is to disable all the language packs you don't use. Are you using KDE or Gnome? If you use KDE, the second button you see in the task bar is configurable. Open System Configuration and click Desktop and then Launch Notification or something like that. There's a check box "Enable notifications in task bar". Uncheck it and see if you get rid of the extra button. If nothing changes, go back to that screen and set the time limit below the checkbox to 0 seconds (there was a bug in this configuration option which prevented us from keeping this checkbox unchecked, don't know if it has already been fixed).

I'm using Gnome. If I make a copy of the firefox launcher and remove the %u option from the command, I don't experience 15 seconds of seeing "Starting Firefox Web Browser" button on the Windows List applet and the busy mouse pointer.
I had thought Firefox was busy initializing, but now I find removing the %u makes Firefox seem ready for action immediately.
The %u option is explained here:

Why is this option causing Firefox to give the impression of having a slow startup?

The %u is not needed. I don't know why it is there by default.

Possibly because Firefox is now cached in memory, and not having to be loaded from disc, bit by bit (pun intended). I see no difference to start up time with or without it. But the first time Firefox is fired up, it does take it's own sweet time about it.

This is just a guess since I am not sitting at my F10 box but does the new launcher option have "launch feedback" enabled? Does the old one? I believe that it's an option when you create the new launcher.
