I want to use Aniweather.com latest add-on temperature icons at end of in Bookmarks bar only in my developer profile like personal one since long time. But strange behavior of Bookmarks bar is there; so I am unable to do so. Two images explain that. A blank white colored line appears between navigation & bookmarks bar. When I want to customize all bookmarks disappears. https://db.tt/WfuV0rni https://db.tt/r2LIODpW What can be the solution? Thanks for your help.
