I should precise few more things :
The bug is embarassing when firefox is maximized ( mentionned difficulty to drag and drop a link in left list of favorite bookmarks )
I tried to reproduce it whith another drag ( i.e a link in a message in maximized thunderbird ) and launcher didn't appear .
If I try to drop the link from firefox to the launcher .. this one freezes a few seconds .
