But is very unstable and the 1 password toolbar disappeared. 1pw Version 3.8.1, works great with FireFox 5. Why can't Mozilla leave FireFox alone. I want to use FireFox 5 without the update notice everytime I turn on my machine. Please turn off the notifications.

this is not a reply to my question. The update of 1password to be used with firefox 6 is totally inadequate. The instructions on how to fill forms, use the wallet etc are not working! How do I revert to Firefox 5?

Sorry, Firefox 6 was a security update for Firefox 5.

Firefox 3.6.20 and Firefox 5.0 are the two currently supported versions.

I understand that. i would like to revert or downgrade to firefox 5.0 hbow do I do so?

I have been waiting for days for a response to complaints regarding Firefox 6. On one occasion, nothing and on another I was referred to a link that did not help at all!
