The problem is that one of the plug-ins or extensions has a bug in it, which causes firefox to abort when starting.

When you uninstall firefox, these extensions are not removed and so poison firefox when you reinstall it. You need to uninstall firefox, remove the following directories, then reinstall firefox.

Remove:

C:\Program Files\Mozilla Firefox

C:\Documents and Settings\%26lt;your username%26gt;\Application Data\Mozilla\Firefox

That will fix your problem.
i think you have old version of Mozilla Firefox.so go to yahoo search and browse for Mozilla Firefox 2 pack.its free.so download it to your computer.do not give direct run.first save it to your system.close all other application that running in your system.then run the software.and restart.it will work for you.for sure.
if you have more than one browser on your pc then one of them has to be the default browser? to avoid conflict within your pc
Install internet explorer and see if that works?
