By default, Google Chrome asks for confirmation when a site automatically tries to download files one at a time. However, if you want to block all attempts independently of the site or blacklist a particular site, follow these steps.
Sometimes, when downloading a file in a browser, the Web site sometimes tries to download another file immediately after the first one ends. While there are legitimate circumstances ̵
Disabling multiple automatic file downloads
Start Chrome, click the menu icon, and then click Settings. You can type
chrome: // settings / into the omnibox to get there directly.
Once on the Settings tab Scroll down and click on "Advanced".
Scroll down to the "Privacy and Security" section and click "Site Settings."
Scroll down the list of settings until you see the "Automatic downloads" option. Click on it.
By default, the feature asks for permission when a site tries to download files one at a time. This is the recommended behavior. However, if you want to prevent multiple files from being downloaded automatically on all websites, turn off the switch.
Done. You will no longer receive a prompt when a site attempts to download multiple files one at a time.
How to enable automatic file downloads, but block specific sites
It is not recommended to globally disable the automatic successive file downloads Block any attempt, regardless of where it originated, to be legitimate, which you may automatically download. However, if you still want to enable this feature and block certain websites that you believe are downloading multiple files, you can blacklist a site instead.
Go back to Settings> Site Settings> Automatic Downloads, or enter
chrome: // settings / content / automaticDownloads into the Omnibox and press Enter. Set the switch to the On position.
Now click on the "Add" button next to the heading Block.
Enter the URL of the Web site for which you want to create a blacklist for automatically downloading successive files, and then click Add.
If you are providing the web address and want to block the entire site, use the prefix
[*.] to intercept it. All subdomains from the site, as in the example above.
That's all there is to do. Repeat this process for so many sites trying to download multiple files. If this site attempts to download multiple files, Chrome automatically blocks the attempt and does not bother you with a prompt.
