The best help would have been, to not make the satanic update from hell. Been with Firefox from PC day one. If something works fine leave it alone. If improvements are needed make sure they are improvements. This latest update has been made by an agent provocateur, with the help of a saboteur. Someone who hates Firefox & wishes its demise. I have spent hours trying to sort it & have made some improvements. It will never be like it was before that criminal update. Firefox R.I.P. gone but not forgotten. You will always have a place in my heart. Why they murdered you we may never know.
