"mailto" will not open a new compose message screen within an webmail service. However, there are ways you can fix this so webmail services will work.
(Gmail) Chrome:
- Go to Gmail in Chrome, & you should see a double diamond icon in the right side of the Omnibar (what Google calls the address bar).
- Click on that little double diamond icon & a little sheet should appear that asks “Allow mail.google.com to open all email links?”.
- Select Allow & then click on Done. The sheet should disappear, & so should the double diamond icon.
Firefox
- Click on the hamburger menu (the 3 lines on top of each other, which looks just like a hamburger) in the top right of Firefox. A panel should open with a bunch of icons on it.
- Click on the Preferences (or Options if you’re on Windows) icon in the panel. The Preferences window should open.
- Click on the Applications button at the top of the Preferences window.
- In the Search box at the top of the Applications tab, enter
mailto.- You should see mailto under the Content Type column.
- Under the Action column, choose Use Gmail from the select list.
(If you’re on a Mac, close the Preferences window.If you’re on Windows, click the OK button to close the Options window.)
Safari:
- You want to install the Mailto: extension.
- Click on the Install Now button to install it.
- Once it’s installed, the Mailto: Options window should immediately open in a new tab in Safari.
- Select the Gmail radio button & then close the Mailto: Settings tab.
