I'm sorry you've run into some trouble with 1Password 3. Thanks for reaching out to us for help here in the 1Password forums. I hope you don't mind, I've moved this post into the 1Password 3 for Mac legacy forum.
Yes, unfortunately there are a few known compatibility issues when using 1Password 3 with modern browsers and OS X 10.11, so upgrading 1Password is a great idea. The good news is that your 1Password 3 license key will get you 50% off a 1Password 6 license in our upgrade store.
Here's a step-by-step guide to safely upgrading from v3 to v6.
Let us know if you have any other questions for us, we're always happy to help! :)
