1Password for Safari not working correctly in macOS 15.6.1 and Safari 18
The title says it all. I see the issue is discussed in other places. Opening a site in a new tab does not fix, restarting Safari does not fix for me. Reinstalling 1Password for Safari doesn't fix...
I may have discovered my problem. I use an app called Cookie that deletes caches, trackers, etc. from "non-favorite" sites when Safari closes. If I enable 1Password for Safari in Cookie as a "favorite", so its caches are no longer deleted, the extension seems to be working (more) normally. We'll see, I guess.

ModeratorHello bogard​! 👋
I'm sorry that 1Password isn't working correctly in Safari on your Mac. Can you share details of the problem you’re experiencing? Any information you can provide, such as an error message and steps to reproduce the issue, will help me understand what’s going on and work on a solution.
For example, are you unable to fill and save logins? When the issue occurs can you still open the 1Password pop-up from the toolbar? I look forward to hearing from you.

When I open Safari, and occasionally while using, 1Password extension is not functional. It will not fill in logins and passwords, and the window will not open when I click the icon. If I manually go into Safari settings and deselect, then reselect the extension, it works again, temporarily. When not functioning and trying to fill a password/login, the extension uses very high CPU (100-300%!!) until I reset extension in settings. Restarting Safari does not change this behavior, in fact opening Safari again after quitting reproduces the problem. Reinstalling 1Password for Safari doesn't change the behavior. Rebooting my Mac does not fix the problem. The main application still works. The problem began for me, I think with OS update 15.5 and continues with 15.6 and 15.6.1. I have not reinstalled the OS and am reluctant to. Anyway, extension behavior is very annoying and makes its use in Safari mostly nonfunctional.

Thank you for the reply. I'd like to ask a few more questions so that I can better understand what might be causing the issue:
- Which version of 1Password for Safari are you currently using?
- Did you recently migrate to your current Mac from a previous Mac?
- Are you using an Apple Silicon or Intel-based Mac? You can check by clicking on the Apple menu  in the menu bar > About This Mac
I look forward to hearing from you.-Dave

- 1Password for Safari 8.11.8
- No. It is a 2019 iMac
- Intel. I do have an M4 MacBook and have not had this issue on it.
- as I mentioned, I can temporarily restore the extension functionality by deselecting/reselecting the extension in Safari settings.
