Hello i found a solution. maybe you will implement it in the plugin.
i will give an example for facebook. so anybody cann use this to create pop up’s for the other share buttons.
1: go to plugins/editor
2: choose Simple Share buttons Adder
3: select simple-share-buttons-adder.php
4: search for facebook.com till you find this code
$htmlShareButtons .= '<a id="ssba_facebook_share" href="https://www.facebook.com/sharer.php?u=' . $urlCurrentPage . '" ' . //($arrSettings['ssba_share_new_window'] == 'Y' ? 'target="_blank"' : NULL) . '>';
5: replace it with the folowing code
$htmlShareButtons .= '<a id="ssba_facebook_share" href=\'javascript:PopUp("https://www.facebook.com/sharer.php?u=' . $urlCurrentPage . '")\'>';
6: enjoy!
