I am just recovering from a reformat of my computer. With a totally new install of Windows, I also had to reinstall Firefox and all my extentions. Will I stll be able to get to all my generated passwords if this happens again?
Since the passwords are not stored on your hard drive, the answer is
absolutely! So long as you remember your master password and the settings you've used (hash algorithm, l33t, etc.), you're safe.
There was an option in the File menu (Advanced Settings dialog) before 0.6 to export/import these settings to/from a file, but I had to disable it for 0.6. I'm aware it becomes more important to be able to "backup" these settings through an export feature now that you can define multiple sets of settings ("accounts"), so it will be reinstated shortly.
