Download blob files via Trusted Sites

We are trying to allow downloads of blob objects (documents). We have implemented the trusted sites steps documented for IE here - https://docs.microsoft.com/en-us/archive/blogs/askie/how-to-enable-blob-downloads-in-ie-through-in-trusted-sites

And it works for IE, but in Edge (latest version) we cannot download the documents, no matter what we do. Anyone know anything to do?

Hi @ReuvyGroovy-1141

For better understanding the issue, I want to confirm somthing with you:

  1. Have you used F12 dev tools in Edge to check if there's any error in Edge?

  2. How do you set the Automatic downloads in Edge settings? You can check the setting under this url in Edge: edge://settings/content/automaticDownloads.

  3. Are you the developer of the download site? If so, can you please provide the code snippet which you used in the blob file download?

This setting is applicable in Internet Explorer only.
You should also download and deploy GPO for Microsoft Edge:

I don't see how GPOs will help
Where does it star the Edge doesn't support this and why?

@ReuvyGroovy-1141 I don't say GPO. Please look at the first comment in the question, I ask about:

  1. Have you used F12 dev tools in Edge to check if there's any error in Edge?

  2. How do you set the Automatic downloads in Edge settings? You can check the setting under this url in Edge: edge://settings/content/automaticDownloads.

  3. Are you the developer of the download site? If so, can you please provide the code snippet which you used in the blob file download?

This is very simple, and not need for F12.

This is connected to the Site-Zone Mapping. When we change the registry value for 1806/7/8 from 0 (allowed) to 3 (blocked) it works. This is the same issue documented in the above article regarding IE, just with Chrome & Edge it doesn't work, but with IE it does.

@ReuvyGroovy-1141

Edge Chromium doesn't have security zone settings, so it is reasonable the steps in the article doesn't work for Edge.

If you want to configure Edge settings indeed you need to configure it through GPO. Please check this policy: DownloadRestrictions. It configures the type of downloads that Microsoft Edge completely blocks, without letting users override the security decision.

I ask you to use F12 because I want to know what error it shows when it doesn't work in Edge. Edge doesn't support msSaveBlob method so if the download page uses this method to download blob file, it will never work in Edge and Chrome.
