Change Firefox default email client for mailto links

[jputting]

Hi,

I would like to know how to change the default Firefox handling of mailto links so that they open my outlook.com webmail service.

I have investigated the Firefox Preferences and only have the following options:

Use Mail

Use Yahoo! Mail

Use Gmail

Use Other:
When selected this simply opens a list of installed Applications on my mac to choose from.

Can someone please advise what I need to change so that Firefox will open outlook.com when using mailto links.

Perhaps there is a Firefox Add-on which can do this easily.

I am using Firefox 64.0(64 BIt) installed on macOS Mojave 10.14.2

Hi eisneun,

I have followed the instructions given on that webpage.

At first I could not get this to work properly, but then I noticed that the link provided sent me to advice given at the tail end of this thread.

I went back further and read the whole thing from the start and found the missing needed information about using the Firefox Web Console.

I have had success in sending mailto links to outlook.com

The Firefox Application Preferences now list: use Outlook Live OWA as an option.

Everything now seems to be working as desired.

Many thanks for your quick response.

Is that method insanely slow for you, and the To has "mailto:" before the address?

I found a faster URL, but it doesn't navigate back to the Inbox when you're done, you need to close the pop-out tab. As another option, I created an extension that integrates into the right-click context menu: https://addons.mozilla.org/firefox/addo ... -link-fix/

Hi jscher2000,

I did notice that method did add the"mailto" before the address which required correcting before sending an email, This method didn't seem at all slow as outlook.com email composing/send page opened with no noticeable delay.

However this was the only solution provided here until you posted with your helpful advice regarding your Add-on.

I have tried your Add-on and it indeed is a better way of opening these mailto links.

Many thanks for your help.
