My old computer crashed went out and bought a new one. how can i retrieve my old bookmark and passwords. no I did not save them. I thought firefox did.
I am sorry to hear about your old computer crashing, and understand that you would like to recover the bookmarks and passwords that you had stored.
If you still have access to the files in your old computer, you should check out the article about Recovering important data from an old profile.
If you had Firefox Sync enabled, you may be able to recover your account information.
Please let us know if this solves your problem.
Note that the "AppData" folder in Windows Vista and later Windows 7+ versions is a hidden folder.
