Greetings, For many years, I could easily access My most important Bookmarks, from a button, located to the right of the FireFox search bar. Over approx. the past ten days, not only did My "Add-ons" NoScript, & Malwarebytes, that were located further to the right of the "Bookmarks Button" disappear, but also the "Bookmarks Button". I found my add-ons still listed via the Extensions-Add-ons tab, but,.... I could not move them back to my "Tool Bar", nor could I activate them. I tried many different ways to get NoScript & Malwarebytes back to the Tool Bar, & Truthfully, I can not remember how I got them returned to the Tool Bar. Now here's the Major Problem,..... I had No Need to Access my "Bookmarks contained in the Main menu" during this time period, nor did I notice that the "Book Marks Button" was gone. Several days ago, I had to retrieve Data contained in the "Book Mark Menu", & I was absolutely Shocked to see that it was gone! There is literally Eight Years of Personal Data, Research, & More in that "Book Mark Section". I took off work, after completing a Job, since last thurs., & after doing a lot of Chaotic Searching, I found that somehow, for some reason, Firefox decided to move my Access to the Book Mark menu, to the "Library", without Any Notice Whatsoever! I Absolutely do not care for where they are now, nor the fact, that I have to go through a longer process just to Access them. How do I return My "Book Marks Button" back to the Firefox Tool Bar?
