//
// Initial "old search" script ported from old Firefox versions by Aris
//
//
// Feature (not optional): search glass is always visible at search bars end (like with "old" search)
// Feature (not optional): search button shows current search engines icon (like with "old" search)
// Feature (not optional): search buttons dropmarker is always visible (like with "old" search)
//
// Option: clear search input after search
// Option: revert to first search engine in list after search
// Option: old search engine selection popup
// Option: hide 'add engines' '+' indicator
// Option: hide 'oneoff' search engines (engines at popups bottom)
// Option: hide placeholder text 'Search'
// Option: swap the icons of search engine button and go button
// Option: show icons and search engine names instead of only icons
// Option: select search engine by scrolling mouse wheel over search bars button

// [!] Default browser feature: search engine can be changed inside default/modern popup by right-clicking
//     search icon and selecting 'Set As Default Search Engine' menuitem.
