Is multiAccounts - multi accounts for any sites safe?

Medium risk

multiAccounts modifies subframe headers to remove CSP and X-Frame-Options after site access is granted.

The extension uses a declarative network request rule on subframes that sets request headers and removes content-security-policy and X-Frame-Options from matched responses. If the user grants access for all webpages, that rule is not limited to a single account frame. Its popup also sends error reports to bug-collector.noterail.workers.dev, and some account operation failures append the active tab or account URL to the error stack.
