I also had this problem. But I was able to fix it by doing the following:
1. Open 1Password app (not extension) 2. Click on the "All Accounts" dropdown 3. Click on "Settings" in the dropdown 4. Select "Browser" from the left sidebar 5. Click on "Add Browser" under the "Connect to additional browsers" section 6. Select Orion 7. Restart and everything works as expected
