Hello. I'm using Windows 11 on a desktop pc. I just downloaded Firefox from internet.

Questions: 1. I don't see "About". How can I tell what version of Firefox I have? 2. My browser bar across the top of the screen has buttons ">>" and "Other Bookmarks", with a different set of bookmarks in each. Why are there two? 3. The same toolbar has specific websites appearing on it, like McAfee Security, etc., some of which are not found in ">>" for "Other Bookmarks". How do I get rid of them without getting rid of the buttons for ">>" and "Other Bookmarks" (which I use)? 4. How do I import the bookmarks from an html file which is on my harddrive? 5. Is there any way I can a list of URLs I have visited? Where? If so, can I have it cleared whenever I exit Firefox? 6. Firefox used to have a white screen, now it has a yellowish screen like all my other Windows programs. Can I set it to white?
