User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:53.0) Gecko/20100101 Firefox/53.0 Build ID: 20170418123315 Steps to reproduce: STR: 1. Take any URL, example: www.google.com 2. Drag it into any bookmark folder to save it there. 3. Drag the same URL, again into the same folder. 4. Now you have www.google.com twice in the same folder Actual results: Exactly same URL bookmark is duplicated in the folder Expected results: Bookmarks could be tested to see if they are of the same URL, if they are: Either silently fail to add the bookmark OR Display a little tooltip or message that it is already saved
(In reply to amar.lakshya from comment #0) > Bookmarks could be tested to see if they are of the same URL, > if they are: > Either silently fail to add the bookmark > OR > Display a little tooltip or message that it is already saved Both options are expensive to code and to maintain. While removing an inadvertently created bookmark is a one click for the user. We also have UNDO from the Library window that can undo any bookmark operation. So, I don't think we are going to add this protection step.
