can anyone tell me what helper.exe is

i was updating firefox 3.0.4 to firefox 3.0.5 and when it was restarting comodo asked me whether or not to allow helper.exe. what does this file name have to do with firefox 3 and has anyone else had this problem?

Yes, helper.exe is a process that Mozilla (FF/TB) uses to update/uninstall.
I’ve marked it “Installer / Updater”.

You’ll find it the uninstall folder for firefox.
