We use a custom protocol handler here where I work that just acts as a file path proxy essentially so that our sales users can click a link in our admin website and have it open the explorer window to the correct folder.

So this was something that registers itself with the registry, and then when clicked on, prompts the user if they want to open the link in "sterlingstorage" (our handler's name), and asks if they always want to open it this way.

It seems though they've removed the checkbox to always remember?

chrome prompt

Any way to get this stop showing up for every click again like it used to?


Are you using Chrome 77? Than you are not the only one with this problem. https://support.google.com/chrome/thread/14194567?hl=en


This is intended The "always open these types of links in the associated app" checkbox is missing because the devs discussed that it wasn't right as there is no option to undo such a choice. Can't make it better than that. Sorry, I'm just here to give you information.

So it looks like for now, you don't really have an option. They removed this option because once you click the checkbox "remember", you can't undo that choice. So they just deleted this feature (as the source link states).

I just found a way to re-enable the checkbox on Windows.
You can follow these steps:

  1. Open regedit.exe as Administrator
  2. Go to the key


  3. Open or add the dword name 'ExternalProtocolDialogShowAlwaysOpenCheckbox' and set it to 1.
  4. Restart Chrome and test your custom protocol. It will show the checkbox again.

You CAN undo an allowed protocol, but you will need to edit the preferences file under your profile folder and search for "protocol_handler": There is currently no undo option in the Chrome GUI.
