I just did an update in Mavericks for Safari 7.1.

After installation all of a sudden my toolbar looks so naked. WHERE THE HELL ARE MY EXTENSIONS I HAD IN THERE?

I looked all over the Menu, checked customize Toolbar and didn’t see anything about Extensions.

A bit of searching on Google and I found what’s needed. Oh so now one needs to actually “enable” each extension all over again in PREFERENCES / EXTENSIONS.

There is a Check Box for each extension to “Enable” the extension. Do that and voila, once again they appear on the Toolbar.

This is a bit of a pain but I imagine Apple decided this would force users to know if any extensions have been installed they are not aware of?
