Well, Social Choreographer, I have the same problem, I'm using FF 18.0.02 and 1Password 184.108.40.2067.
The addon doesn't work, when I enter the master password to unlock, the connection fails.
I'm also using Chrome and Safari, both work fine.
The error message, as I entered the password:Timestamp: 12.02.2013 19:21:15
Error: [Exception... "'PopupNotifications_show: invalid browser' when calling method: [nsILoginManagerPrompter::promptToSavePassword]" nsresult: "0x8057001e (NS_ERROR_XPC_JS_THREW_STRING)" location: "JS frame :: resource://gre/components/nsLoginManager.js :: :: line 914" data: no]
Then, while the connection trial counts up, always the warning:[DATASOURCE] Warning: no key found in keys table.
I appreciate your help!
Thanks in anticipation
I am using Mozilla FF 18.0.2 and 1Password 220.127.116.117 also. The add-on does not work. It still works fine on Chrome. Please fix.
I split your posts into a separate topic as you're on Windows whereas the original topic was for the Mac app and the errors are not related.
Please try the instructions in this guide and restart Firefox after this, see if it'll work now.
