Did you uninstall Firefox 0.8 before installing 0.9?

Also, can  you try to run Firefox in safe mode (start menu/programs/firefox)?

1) I did not have Firefox 0.8 (or earlier) installed, so n/A.

2) No, the application will not run in safe mode either.  I get no error 
message and there is no visual sign that the PC has done anything.  From 
Windows Task Manager in Processes I see that firefox.exe is consuming 8,012k 
of memory and yet if I look at Applications there is no mention of Firefox.

3) Firefox initially installed and ran OK, but upon adding a number of add-ins 
the program would not start again.  I did not re-start after adding each add-
in so I do not know if the problem is caused by a particular add-in or is due 
to an accumulation problem.

4) I did un-install Firefox 0.9 using add/remove programs, re-started and re-
installed Firefox 0.9 - Program still would not start up.

I am having the same problem.  On initial installation the browser opened right
up, but after installing about 7 plug in extensions, and then trying to reopen,
it won't.  I also tried uninstalling and reinstalling stil won't.  I am running
Windows XP PRO.

I have precisely the same problem. .
The browser (Firefox091) was working very well, but now it won´t start anymore
after installing a  couple of extensions (around 10).  I have tried unistall,
installing  agai, and re-starting the computer but to no avail. However, the
task manager (windows XP) tells me that the program is running.. 
The only problem I had previously had was when ussing the IE-View extension: I
automatically wass redirected towards Internet Explorer without being able to
use Firefox. I had  to uninstall that extension en then it was OK..

Can you reproduce this with a new profile, now that Safe Mode and reinstalling
doesn't work?

If not, ->WORKSFORME.

I've moved to Startup and Profile System and edited the Summary to be more
specific.  Does this still happen in 0.9.2?

No response from user -> WFM.

If you can follow the instructions above with the latest version and still
reproduce, reopen this with more details.
