I have been a Firefox user for many, many years. I started getting the Subject message: "The bookmarks and history system will not be functional" error message this evening. I started to "Fix" this error based on the Mozilla Support page. Actually, I first tried restarting my computer and that didn't correct the problem. I then noticed I could "sign off" Firefox which I thought I'd do and sign back in. I didn't notice until after the fact that my Firefox account was tied to a very old email address I once used that is no longer active "commish3@bellsouth.net". When I tried signing back into Firefox using that old email account, it said a security code would be sent to that old email address. Problem is I no longer have access to that email account. 1) Is there a way I can sign back in and have a security code sent to my current email address: tad3.dickinson@gmail.com ? 2) Can you assist with restoring my bookmarks. Again, years of building these bookmarks that I'm very dependent on. Thanks, Tad Dickinson
