My new extension **[Page Mail](https://addons.mozilla.org/en-US/firefox/addon/page-mail/)** supports mailto:, Gmail and Outlook on desktop, opening a compose window pre-filled with Subject and Body using **browser.tabs.create()**, but in enhancing it for Android, I can only get mailto: to work that way by using **window.open()** (with annoying Allow/Deny confirmation). With **Gmail** or **Outlook** I get the **Inbox**.
Has anyone figured out a way to open a compose window with special Gmail and/or Outlook links in an Android extension? Thanks!
```auto
// Compose URL templates
const MAILTO_TEMPLATE = "mailto:?subject={SUBJECT}&body={BODY}";
const GMAIL_TEMPLATE = "https://mail.google.com/mail/?view=cm&fs=1&su={SUBJECT}&body={BODY}";
const OUTLOOK_TEMPLATE = "https://outlook.live.com/mail/0/deeplink/compose?subject={SUBJECT}&body={BODY}";
```

Just to make sure I follow, you’re trying to open the compose view for Gmail/Outlook as web page in Firefox for Android, right?
If so, I’m seeing this too. I tested by opening the Gmail template URL on desktop using Firefox’s [Responsive Design](https://firefox-source-docs.mozilla.org/devtools-user/responsive_design_mode/) mode to emulate a Samsung phone. I haven’t looked into Outlook.
It seems like Gmail is doing user agent detection and serving a different experience to mobile users. Adding the hash `#co` (e.g. `https://mail.google.com/mail/#co`) will open the compose view, but as far as I can tell there’s no way to provide a default subject, recipient, or body.

@dotproto
Perplexity agrees with you ([link](https://www.perplexity.ai/search/why-does-window-open-in-a-fire-i29QcaeTQra_tfqhptabRA)), and suggests there is “No Reliable Web-Only Solution” other than using mailto (which is what I do now).
I was just hoping that someone had found a work-around that Perplexity hasn’t found.
