Why is my customized toolbar not being saved when I restart Safari?

"There is a well known issue with Evernote's Safari Clipper. The Evernote folks have fixed it once, but the fix actually cause the Evernote Safari Clipper plugin to overwrite other changes in the Toolbar.

The best solution at this point, is to Go into Evernote and turn off the Safari Clipper, and use the MenuBar Clipper instead."
