I upgraded to 1Password 8 yesterday. Since upgrading extensions in Firefox and chrome not working.

Hi @Kris_Shannon:

Great question. 1Password keeps a full local copy of your items when you're offline. You can continue to lock and unlock 1Password and view and edit your items when you're disconnected from the internet. 1Password in the browser will also continue to work to fill, however changes made in 1Password for desktop won't be available in 1Password in the browser, and you won't be able to make any changes using 1Password in the browser.

Thank you for your feedback. To be 100% clear, when your device is not connected to the outside internet, 1Password in the browser still has a local copy of your items.
