I am using 1Password on Windows 7. Every time that I fill a login form using the firefox (v5.0) extension it checks for a new version of 1password. This obviously slows the process down considerably. I have disabled updates in 1password and the behaviour remains. Launching the program first also has no impact. THe same behaviour is not present in Chrome - it loads from the extension without checking for updates.
Thanks in advance for any information.
