Hi. I assume this problem is similar to what I encountered a couple of weeks ago. I switched to FF in the meantime.
I will get back to you once I fully reproduce it locally. Here's a summary out of the top of my head.
- User visits website
- Website prompts certificate and attempts to access keyring
- User authorizes access with always allow
- Website stops loading with 403.
However, if you don't always allow, it will prompt to unlock the keyring for every request sent to the target domain. Only then the website starts loading.
