I had a large address book when I quit my 20yr job. Was under the gun to get info off the computer and leave and rather than go to the website (DUH) I tried some made up 'copy' to a stick, and when I went to 'paste' it into my new thunderbird personal addresses on the new home laptop, I created some mess in the address book that LITERALLY created over a million entries in the personal address book. I had to disable the start typing and match function to be able to enter an address in a new write email, and I cannot open my address book tab because it defaults to trying to open this huge file, and it goes into not responding now. I actually got it open once, highlighted first entry (blank) and scrolled to last entry and shift highlight and entered delete. but an hour later it still was working so I ended task, and now I can't even get it to pull up the list. I admit I'm an idiot, but can it be fixed???????
