I have added the safari extension a number of times. I have downloaded the 1password installer and double clicked. The extension installs and is enabled in Safari Preferences. The icon is visible on the Safari toolbar. When I close Safari and then re-open, the icon is no longer in the toolbar and there is no extension shown in Safari Preferences. This is happening with Evernote as well.
Early 2011 Macbook Pro 15"
New install of Yosemite that has been updated to 10.10.1
Safari 8.0 (10600.1.25.1)
1Password 5.0.2 (502007)
1Password is visible on the menu bar.
Can you help me get the extension to remain on the Safari Toolbar?
