• Fixed a bug where upon right-clicking to edit an address, the edit does not get saved

• Fixed bug which caused icons to get lost at startup and when disabling/enabling the extension in preferences.
• Increased the right-click target size for separators so they can be more easily removed
• Added an “Add Link” button to the Settings page
• Added the ability to delete separators from the settings page

Installation & Upgrade Notes:

Upgrades
This version should upgrade over an existing install without losing icons, but to be safe, if users are on version 1.2 I recommend they copy their links from the Safari preferences pane under Extensions.

If users are on version 1.3, I recommend they backup their links and settings from the FaviconBar settings screen to a file. Click the gear, then click Download next to "Save settings and links to a file". If the file shows up as text instead of a download, go to the File menu and choose Save As then save it in a safe location.

Installation
Installation can be completed by double-clicking on the FaviconBar.safariextz file and clicking "Trust"

A known security feature with Safari sometimes prevents installation of extensions downloaded from the internet. If the extension does not install when you click the "Trust" button, follow the steps below:

To install a .safariextz file, go to:

System Preferences > Keyboard > Shortcuts > Keyboard (for OS X 10.11.4+)
or
System Preferences > Keyboard > Shortcuts > Full Keyboard Access (for OS X 10.11.1 to 10.11.3)
Then at the bottom of that dialog box, change the Full Keyboard Access:... option from Text boxes and lists only to All controls. You can then dismiss that System Preferences window.

Then, return to installing the extension. Double click your Safari Extension file and when the "Are you sure you want to install..." dialog box appears, do not click on the Trust button. Instead, use tab to select the Trust button and then confirm by hitting space. That should install the extension as required.
