Be careful with old versions!

Added Options button functionality.
Fixed incorrect display on new tab.
I would like to thank annes3200, relequestual and YellowSnow for helping me with this.
There can be set the delay, enable or disable the addon, enable/disable CTRL key.
Also changed the function or CTRL+ALT+z shortcut. It now enables or disables the addon, meaning it permanently shows or autohides the bookmarks.
By pressing CTRL key and moving the mouse over the browser's menu, the toolbar will appear.
The toolbar disappears in 2 seconds by moving the mouse away (on the web page for example).
The Bookmark can be un-hidden by pressing CTRL+ALT+z
