After the upgrade to firefox 9.01 with windows xp I get every time firefox tries to launch the error message "This application has failed to start because MOZCRT19.dll was not found. Re-installing the application may fix this problem".

Well, re-installing does not fix this problem!

I even de-installed firefox, cleared all folders with the hint of mozilla or firefox in its name and did the same with the registry, re-installed firefox 9.01 but always get the same result.

If you use ZoneAlarm Extreme Security then disable Virtualization and reinstall Firefox.
