I have 3 computers running Windows 7 Professional 64 bit. Only one of them has a Norton search bar in Firefox 42.
The rest do not have it nor identity safe. All using version 188.8.131.52
.Just an FYI
Have you tried restarting those computers a few times? That fixed my issue with the update.
Tried that and still nothing.
I see that they have pulled the patch.
I will wait for the improved version
and let you know.
Thanks for the input though.
You are very welcome.
