My current version is 6.0.2. A box appeared a few days ago informing me of an update to 7 (x?). I declined for the time being. Then a Start Page just showed up missing the bookmark tool bar. I tried to import a bar from another browser. Nothing showed up. Then, I went to "Help". First, I clicked on "About Firefox" where I was informed of an update. This time, I tried it. When I clicked on "Apply Update", I received a message; 'Update could not be installed" despite there being no other Firefox browsers running. I went back to "Help" and clicked on "Firefox Help". A page came up with the URL in place, but the page would not load ("Cannot find server at support.mozilla.com"). After several clicks on "Try Again" with the same result, I copied the URL and pasted it into a different browser, from which I am now working. Before sending this question, I tried the two procedures ("Manual Backup" and "Restoring From Backup") found on Bookmarks/Show All Bookmarks/Import And Backup/Restore, using both "stored backups" from Mozilla's Profile folder and "Choose a file", as well as Bookmarks/Show ... /Backup. In each case, the response was, "Unable to process the backup file". I had previously tried another method I found on Google which involved copying and saving a Mozilla backup file (this is the file I used in the procedure above - "Choose a File") found in the C:/Documents And Settings/.../Profile Folder, then renaming the original file "backup.HTML" and saving it in a folder one level up from its original location. The Bookmark bar was to show up after shutting down and reopening Mozilla - it never happened. I replaced the original backup file. It occurred to me to locate the Bookmark File for this browser (Chrome) and using it in the "Choose a File" method, referred to above. But there is no extension included in the file name, and I was afraid to try it. I'm out of ideas. Is there something else to try?
