Hello users, I use Firefox a very long time and I love it. A few days ago I downloaded Firefox Developer Edition and I use it with the same sync email address, because of bookmarks, passwords and more. But I don't want to use add-ons in Firefox Developer Edition... How can I disable add-ons in developer edition, while add-ons stays enabled in Firefox version? If I use command-line "-safe-mode", I get every time a message about safe-mode before Firefox Developer Edition starts. I hope you have a smart solution for me.
