Mozilla has finally added the support for mailto links in Firefox. The request to add support for maito links to the browser was made 7 years ago and is finally addressed.
The users running Firefox Nightly can head down and follow the steps to enable mailto links in Firefox browser.
- Go to Settings > Apps > Default Apps
- Click Mail under Email option and Choose “Firefox Nightly”
This will now allow users to open mailto links directly inside the Firefox Browser instead of using a third-party app. The feature is currently available for those who are using Firefox Nightly builds and should make it to the public soon. If you’re interested in trying out the feature right now then you can head to Mozilla’s website and download the latest Nightly Build. Do remember that Nightly builds are extremely unstable and can cause issues so install at your own risk.
