I am confused. You say the 1password 3 browser password extensions won't work with 1password 4. Are you talking about the key I installed at the top of Chrome? Mine works and I have not removed it from 1password 3. Don't understand. I have not installed extensions in 1password 4 because you say the 3.9.6 extensions won't work (they do!) and you also say they need to be removed from 3 before installing for version 4. Not only that but ...if I indeed must remove version 3 first, the following is totally unclear: "The easiest way to do this is to save a new login in your web browser. Any login will do, such as the sign in form for these forums. Give it a really obvious name that can't be confused with any existing login, something like "1Password 3 is up to date!". Now, open 1Password 3 and make sure that login is there. You can then safely remove the 1Password 3 browser extension."
