Very nice work, many thanks.
Favicons are retrieved even when the user has set Firefox to block favicons everywhere:
// disable favicons in shortcuts
// disable favicons in tabs and new bookmarks
// disable favicons in web notifications
Having 'Bookmark search plus 2' respect Firefox's favicons' settings would be appreciated.
EDIT after developer's response :
Since it is not possible to synchronize the favicons' display with that of Firefox maybe an option specific yo BSP2 regarding Favicons would do it, as for instance in the 'Flagfox' extension, such as 'Favicons Yes/No'
This is neither an issue nor even a true enhancement, but an option for users who wish not to retrieve Website icons (which by the way also adds time to the process). I think more users than we may imagine block favicons.
The idea is that I don't see why connections to sites would be performed for accomplishing a task (localizing a bookmark in the Library) which is basically an off-line process.
EDIT 2 :
Version 2.0.15 now includes a 'Disable favicon fetching' option : rating updated from 4 to 5 starts.
