I've got Windows 10 and have recently shifted my browser from Chrome to Vivaldi.

However, I cannot get Vivaldi to open email links - it always reverts to Chrome. I have tried looking in default programs, but Vivaldi does not appear as a choice, and it doesn't let me navigate to a program.

Does anyone know how to force a change in the default?

Thanks.

This is the same problem as this question:Unable to set Brave browser as default browser in Windows 10 But the answer provided there no longer works: it is no longer possible to navigate to 

Control Panel\All Control Panel Items\Default Programs\Set Default Programs

in Windows 10. I just get a blank Control panel and the following directory: C:\Windows\System32\control.exe

I found the answer here, and it's a bit crazy: https://forum.vivaldi.net/topic/26413/mailto-protocol/4

Also, don't muck about with the registry - I tried using another answer, and didn't get anywhere. The answer below works perfectly.

The relevant part is:

First, make sure custom handlers are allowed at vivaldi://settings/handlers. [should be chrome://settings/handlers]

Then, close Vivaldi.

Use JSONEdit, to edit "C:\Users\yourusername\AppData\Local\Vivaldi\User Data\Default\Preferences".

Copy the following to the clipboard:

{
   "enabled" : true,
   "ignored_protocol_handlers" : [],
   "registered_protocol_handlers" : [
      {
         "default" : true,
         "protocol" : "mailto",
         "url" : "https://inbox.google.com/?mailto=%s"
      }
   ]
}

Right-click on the root node in the Preferences file in JSONEdit and choose "Paste as child from clipboard". Then, rename the pasted object to "custom_handlers" and save your changes. (This is assuming you don't already have some custom handlers. If you do have some, you just need to add to the registered_protocol_handlers array.

In Vivaldi, go to vivaldi://settings/handlers [should be chrome://settings/handlers], click the 3 dots to the right of the inbox.google.com entry (that's now there) and choose "set as default". Then you can go into Default Apps in Windows and set Vivaldi as the default mail client. Then you should be good to go.

On a side, for Gmail (mail.google.com), it's:

navigator.registerProtocolHandler("mailto", "https://mail.google.com/mail/?extsrc=mailto&url=%s", "mail.google.com");

I didn't have any problems setting the default browser to Vivaldi.

1) Install Vivaldi

2) Open Vivaldi

3) Click Settings from within Vivaldi

4) Click Set as Default

enter image description here

5) From within the Settings UWP application click on the current default program under Web Browser.

enter image description here

6) Select Vivaldi.

7) If Vivaldi is not listed select set the default program by file extension instead.

  • If **Vivaldi** isn't listed then you should uninstall it and reinstall it. It wasn't installed in my VM, I installed it, doing these steps set the default browser when I click a link within an application. You also should change any setting, set to use Chrome, to use **Vivaldi** instead ovbiously. – Ramhound Aug 15 '18 at 02:02
  • Thanks - default browser is all good, just not email - my problem is it won't show in the choice of programs. Will try reinstalling. – Grubbmeister Aug 15 '18 at 03:26
  • Have posted the solution. Your answer deals with the browser default, but not the mailto default, which is what my problem was. – Grubbmeister Aug 15 '18 at 08:43
