I tested this behavior with the KeePassXC-Browser Addon for Firefox and Chrome. Downgrading KeepassXC from 2.5.1 to 2.5.0 fixed the issue, so it seems to be related to the latest version of KeepassXC and not to the browser addon.

Expected Behavior

When browsing to a site, the "KeePassXC-Browser Confirm Access" pop-up requests password access to the credentials stored for this specific site or does not pop-up at all for sites, for which I already granted password access.

Current Behavior

The pop-up requests access to multiple, unrelated sites.

Also, on sites that were already known and that never showed the pop-up after I ticked "Remember this decision", the pop-up requests access to other sites now.

Steps to Reproduce

1. Upgrade KeepassXC to 2.5.1
2. Browse to a site, which requests passwords stored in KeepassXC

Context

Tested on two different Windows desktops, one using Firefox + KeepassXC Browser, the other using Chrome + KeepassXC Browser
