I wanted to connect my (win7) pc to a new keychain for my wife. To start with a clean sheet, I deleted dropbox, 1password and the firefox plugin. After that, I deleted each trace of 1password I could still find on the PC.
After installing dropbox and 1password again, I created a new keychain for my wife. No issues here, syncing with Dropbox works fine.
However, I was suprised on a very negative way when I reinstalled the firefox plugin and wanted to test it with the new keychain. The plugin did not recognize the password of the new account. I tried the password of my old (and unlinked and deleted) keychain and to my surprise it gave me all the data in my old keychain!
I have been trying all night and cannot find a way to remove my old keychain (that should not be on my machine anymore) from the firefox plugin. I have removed and reinstalled over and over but that does not help a bit.
I am also a bit concerned about the safety of my data, as it seems that the firefox plugin stores a mirror of my keychain somewhere (otherwise, the data could not be in it as I completely removed it).
