Yes, it is very-very slow; I'm experiencing a similar, ~30 second, startup time
since I upgraded from .91 to .93.  I've asked my family to leave an instance of
Firefox up at all times to get around this.

bug246283/bug249519 may be the cause.

I also have problems with long startup times with Firefox 0.9.3 and 1.0PR, on
two computers. 

It *clearly* takes a longer time to open a new window, the more Firefox windows
are already open. 

The time measured is the time from I either

1) fire a URL from Start | Run, 
2) fire a URL from the Google DeskBar, or 
3) doubleclick the Firefox shortcut on my desktop, 

and until the new Firefox window appears. 


First computer
--------------

The first computer is a Celeron 1,2 MHz with 768 MB RAM, running Firefox 0.9.3
on a Windows XP Professional (fully updated, including SP2). 

If 1 Firefox window is already open, a new window opens in about 2 seconds. With
7 Firefox windows open, it takes about 5 seconds for a new Firefox window to
appear. This is not including the time to load the web site. 

Installed Firefox extensions: DOM Inspector 1.0, SwitchProxy Tool 1.3, Googlebar
0.9.0.28, Download Manager Tweak 0.5.2, ieview 0.83.


Second computer
---------------

The second computer is a Pentium 4 2,6 GHz with HT and 1 GB RAM, running Firefox
1.0PR on a Windows 2000 (fully updated).

With no Firefox windows open (i.e. firefox.exe not running), it takes 4,5
seconds for the Firefox window to appear, using the method described at the top
of this comment.

With 1 Firefox window open, it takes 1,5 seconds for a second window to appear. 

With 11 Firefox windows open, it takes 5 seconds for a new window to appear. 

If I use Ctrl+N from within Firefox, the startup time for a new window is always
1,5 seconds, no matter how many Firefox windows are open.

Internet Explorer takes 1 second to open a new window, no matter how many IE
windows are already open - even 0.



As I often have many Firefox windows open (10 to 20), this is a real problem for
me. Firefox is a much better browser that IE, so I won't go back to IE, but the
thought has occurred to me. 5 seconds or more just to open a new window is way
too long on a relatively fast computer like the second one mentioned above.

Still the same problem for me in nightly build "Mozilla/5.0 (Windows; U; Windows
NT 5.0; en-US; rv:1.8b) Gecko/20050216 Firefox/1.0+ StumbleUpon/1.999".

Neither Ctrl+N or File | New Window works in this nightly build. Nothing
happens. So I can't test the new window startup time for Ctrl+N.

In Mac OS X 10.3.x, there is no what hangs every time in startup for 30 seconds
or more because 
the problem of prebind does fix(bug246283/bug249519). 

Because prebind is done with background in Mac OS X 10.2.x, only as for first
startup, I think that time hangs. 
This is not avoided.

By the way, I am Windows version Firefox and do not have the experience that
 time hangs for 30 seconds or more in startup. 
I think that it is another cause for Windows. 

WFM?

Ah, I see that I might have put my comments on the wrong bug. My problem is on
Windows and is not 30 seconds, just 2 to 10 seconds.

Comment 10

[Jesper Hertel]

Nope, this must be the right bug. Other bugs mentioning problems that look more
like mine, and that are on Windows, have been marked as duplicates of this bug.
A bit strange, though, as it could look like two different problems.

As a workaround, try the Firefox Preloader -
http://sourceforge.net/projects/ffpreloader/. 

I installed it, and all my problems with slow Firefox startup times where gone.
New windows open almost immediately.

Comment 12

[Jesper Hertel]

I gained an additional speed improvement by disabling the SwitchProxy Tool 1.3.1
extension.

"With a little investigation, it seems that the culprit is the Switch Proxy
extension."

So, this bug is INVALID, because it is not a firefox bug ?
