*		Other Chromium browsers - such as Brave, Arc, and Opera - should be fully compatible with FortiMail Browser Security but are currently not officially supported.
***		It is not possible to block downloads of malicious files.
****		Regular downloads are scanned for malicious content. Downloads that originate from blobs, file URLs, or data URLs aren't scanned for malicious content.
****		In some scenarios, enabling the "Prevent access to downloaded files until the scan is complete" setting doesn't prevent access to the downloaded files before the scan is complete. [See Prevent access to downloaded files until the scan is complete] In these scenarios, if the downloaded file is found to be malicious, the extension will attempt to delete the malicious downloaded file.
