What kind of issues are you having? Can't log in? Can't link? What else?

I logged into sync, but my bookmarks did not reappear. I did not do the add another machine since I had no clue my hard drive would go bad (it was just replaced a couple of months ago and I went through this without any issues). I don't care about the passwords as I know what they are, just the new links I added within the last couple of months are important. I do not care for Chrome, but they do the bookmarks right. I would rather not have a third party add-on storing them either as a security/privacy issue. Windows Repair failure.. no surprise there. Though they changed it so the blue screen of death is now a pink screen...

I will call for help for you.

BTW, as to password add-ons, they all use the Firefox Password Manager. They just tweak it to operate better.
