How do I add Outlook web based email to Firefox mailto links?

Hello,

As the title reads, this is not an option and I would like set this up manually if possible.

I read an old thread from 2016 with steps on how to do it but it appears to no longer work with versions 49+

Cheers.

I read the linked page and the only possible solution found there was to install an extension to handle this. The only available extension that claims to solve the issue when searching is "MailtoWebmails". Once installed along with the "outlook" service what occurs when clicking a mailto link is being forwarded to a blank white page. There is no login or option to compose an email. The rest of the extensions appear to be just various email notifiers.

I did some investigating and it appears the reason "MailtoWebmails" was loading just a blank white page was because of conflict with another extension.

However, when it does finally open an email compose box the address that is automatically filled out to be sent to has "mailto:" infront if it which means it will be sent to the wrong address defeating the entire purpose. I could just login manually and copy and paste the address myself if it's available.

So this still remains unsolved unfortunately.

Hi Avengement, I think there are two parts to the story:

(1) Plain email address links, such as someone@example.com

(2) Using the Email Link command to send someone a link to the current page

For #1:

This might not be worth the hassle: Outlook includes mailto: in front of the address and you need to edit that out by hand. The alternative is to right-click the email address link, Copy Email Address, then create a new message yourself and paste the address. But if you want to try it anyway:

Open your Outlook mailbox. Then

(1) Open Firefox's Web Console in the lower part of the tab below your mailbox. You can do that using either:

  • Ctrl+Shift+k (Mac: Command+Alt+k)
  • "3-bar" menu button > Developer > Web Console
  • (menu bar) Tools > Web Developer > Web Console

(2) Select and copy the following line of script (it's all one line -- ignore the fact that the forum creates links):

navigator.registerProtocolHandler('mailto','https://outlook.live.com/owa/?path=/mail/action/compose&to=%s', 'Outlook.com OWA To');

(3) In the tab with in your mailbox, paste the script next to the caret (>>) at the bottom of the Web Console, and press the Enter key (or Return key) to run the script. The first time, Firefox may ask you to take some action to prove you understand it's dangerous to run scripts from strangers.

An infobar should open at the top of the page. Click "Add Application". You now can close the Web Console by clicking the "X" on its top bar at the right.

Then you can test on an address such as the one earlier in this reply.

For #2:

Outlook doesn't handle the subject line and body correctly, so as a workaround, you can use a bookmarklet. That a little script which you save on your Bookmarks Menu or Bookmarks Toolbar. When you want to send a link to the current page, click the button. Note that bookmarklets may be disabled on higher security pages. I can't do anything about that.

Here's where you install from:
