Why are all versions of Firefox beyond Version 3.6.17 incompatible With Norton Toolbar?
I've had a persistent problem with every new release of Firefox since Version 3.6.19. They are all incompatible with the Norton 360 Toolbar, which included Identity Safe, a feature that automatically saves and fills in all my logins and passwords.
I have consistently refused to inatall any Firefox version beyond 3.6.19 because of this incompatibility. But now my existing Version 3.6.19 had been corrupted and I've had to uninstall it. But when I'm downloaded a new copy of Version 3.6.19, I've been unable to install it. WHY?

Your concept of compatibility is backwards. Toolbar add-ons need to be compatible with the version of Firefox they are to be installed in.
Norton released an update patch for Firefox 5.0 on Tuesday 06-21 when Firefox 5.0 was released. (versus taking their normal six to eight weeks) Some Norton users have reported that the toolbar may not work if the Norton patch was installed before Firefox 5.0, instead if after Firefox 5.0 was already installed.
Have you ever done any updates in Norton ?
Norton supported Fx 5.0 on Jun 21 release day (instead of some 6 weeks later) for example.
That patch is for Norton Internet Security. I use Norton 360. Therefore, the incompatibility issue remains.
