I see this is a known bug but this bookmark sidebar has suddenly started to appear on my desktop when ever I open Firefox and there seems to be no understandable method to turn it off although there are several arcane techniques that require me to go to weird places and change the names of files. No indication of what the unintended consequences of that might be. Is this something you can fix? Will the next update. This is really frustrating. Help please. So to be sure, I do not consider the challenge of getting into the pants of a program to fix a bug to be fun, exciting, interesting, etc. This is a tool and my browser is acting up. That is a pain in the butt not an adventure.
