Is Breez ClickOnce safe?

Clean risk

Breez ClickOnce forwards ClickOnce application URLs from any website to its local native helper after consent.

When a visited page returns a ClickOnce application URL, the extension intercepts the browser response. If local consent is enabled, it sends that URL to the breez.clickonce.clickoncehelper native messaging host and cancels the browser request.
