Hi, I want to block the download of links.
blob:https://
But they are not displayed in BeforeResourceLoad, is there any other option to block them?

You can see them in devtools without any problems.

Hi,

Try using the TChromiumCore.OnBeforeDownload and TChromiumCore.OnDownloadUpdated events to cancel all downloads with the blob URI scheme.

Maybe I didn't understand something, but there's nothing in the downloadItem, how do I see the link?

Hi,

I just checked downloading a blob image manually as described here :
https://www.briskbard.com/forum/viewtopic.php?t=2527

The TMiniBrowserFrm.Chromium1DownloadUpdated procedure in MiniBrowser is triggered with a valid "downloadItem" for the blob image.

Call callback.cancel in that event when downloadItem.Url starts with "blob:"
