Dear Experts,
I was using firefox, tried to upgrade to 1.5. Completed installing the program but doesn't work. Tried to uninstall to reinstall but I can not uninstall it now. I think IE is being villian. It says firefox.exe is running in task manager and I cannot deleate it from there.

deleting from task manager?
all you do is end the program(process) runnin the the task manager, you can't delete.
i don't know if thats what you're asking. but if you want to uninstall, then you have to end the complete process.

ctrl+alt+delete go to task manager, right click firefox.exe, and click end tree! then continue uninstall from control panel!

Thanks,
I tried all those things. Did end task on applicationand as you said highlighted firefox.exe in the processes and clicked end process tree. Nothing happens. I am not able to uninstall firefox yet. Is there anything I can do through Program files?

Try uninstalling IE from contol panel :"Add Remove Program Wizard". Then uninstall Firefox same way. After that install fresh firefox. Should work, unless you have some registry conflict issues, in which case you need to rectify the registry values set by the firefox browser software. But first do try as I said and see where you go.

reboot.

Reboot..if it doesn't work "boot it!!" :D
