Back to the original thread:
FxeGrid still will not work on Safari 6 Mt Lion or Lion.
I did upgrade to Mt Lion and observed same.
I did not see a quick fix, but will work this weekend.
In the mean time I suggest using the mini browser in the app:
Fx eGrid>Choose Browser>Fx eGrid.
By still using the app you will get notified when a new version is available.
Yes, it not full featured and you may sometimes still want to login directly with Safari.
