I had accidentally erased some squilte files in my previous copy of Firefox and to make a long story short, I had followed the instructions in trying to restore my bookmarks from a previous json file date via browser restore. When I had attempted this feat, the browser slows down and I keep getting an unresponsive script error message and I have attempted this feat several times and needless to say, I need some assistance in fixing this. Please help me and thanks in advance.
