I am using Windows 7 Professional and Firefox 26.0
I changed my master password and know all my saved logins are missing!
How do I recover them?
I'm sorry you're having that problem, @TimTDP.
If you launch the main 1Password program, do you see all your Login items and other saved data, as expected?
If so, you need to clear Firefox's cached copy of your 1Password data, as follows:
In Firefox, remove the 1Password extension.
Delete Firefox's temporary copy of your 1Password data:
a. Type this in the Firefox address field:
b. Press Enter.
c. Under Application Basics, click the Show Folder button.
d. Quit Firefox.
e. In the Explorer window that appears, go "up" one level to the parent folder.
f. Drag the OnePassword.sqlite file from that folder to the Desktop.
In 1Password, re-install the Firefox extension.
Once everything is working well, you can safely move the OnePassword.sqlite file on the Desktop to the Trash.
I hope that helps, @TimTDP. Please let us know how it goes.
