disable the "send anyways" warning when nothing in subject

[dazco]

Every time i send w/o anything in the subject line i get the "send anyways?" prompt. I cannot find a way to disable that other then 2 different addons, neoither of which thunderbird will install. I guess it's due to the version, i have the latest 78.0.1.

The send without subject add-on used to be the normal workaround. You could get it to work with version 60 by setting "extensions.strictCompatibility" to "false" in the config editor. However, it's a legacy add-on so there is no way to get it to work in version 78.

The "Allow Empty Subject" add-on seemed to have stopped working about 5 years ago.

I'm not aware of a setting to do what you want. I tried creating a template with a couple of spaces in the Subject and double clicking on it rather than using the Write button but it complained when I tried to send it. However, adding a single period as the subject in the template works.

Is there a way to set it so theres a period in the subject by default? Seems like u r suggesting that (template?) but i have no idea how.

Create a message that has no recipient or content, add a period to the subject and use save -> template to save it as a template in the templates folder. Then double click on that template rather than pressing the write button whenever you want to compose a message.

You could use the userChromeJS extension to send messages without a subject and without a confirm prompt. (for advanced users only)

Code: Select all

/* Thunderbird userChrome.js */

// Thunderbird 68 uses the messengercompose.xul page.
// Thunderbird 78 uses the messengercompose.xhtml page.

(function () {
  if (location == "chrome://messenger/content/messengercompose/messengercompose.xul" ||
      location == "chrome://messenger/content/messengercompose/messengercompose.xhtml") {
    try {
      var a = "    // Remind the person if there isn't a subject" + "\n";
      var b = '    if (subject == "") {';
      var c = "    if (false) {";
      eval("GenericSendMessage = " + GenericSendMessage.toString().
        replace(a + b, a + c));
    } catch (e) {
      Components.utils.reportError(e);
    }
  }
})();

userChromeJS by jikamens (compatible with TB 68 and TB 78)

P.S.

Thanks to Jorg K for porting userChromeJS to Thunderbird 78.

Alternative solution...

You could use the userChromeJS extension to automatically click the "Send Without Subject" button. (for advanced users only)

Code: Select all

/* Thunderbird userChrome.js */

(function () {
  if (location == "chrome://messenger/content/messengercompose/messengercompose.xhtml") {
    Services.ww.registerNotification(function onOpen(aSubject, aTopic, aData) {
      if (aTopic == "domwindowopened" && aSubject instanceof Components.interfaces.nsIDOMWindow) {
        var chromeWindow = aSubject;
        chromeWindow.addEventListener("DOMContentLoaded", function () {
          if (chromeWindow.document.documentURI == "chrome://global/content/commonDialog.xhtml") {
            chromeWindow.setTimeout(function () {
              try {
                var dialog = chromeWindow.document.getElementById("commonDialog");
                var button = dialog.shadowRoot.querySelector('button[label="Send Without Subject"]');
                if (button) {
                  button.click();
                }
              } catch (e) {
                Components.utils.reportError(e);
              }
            }, 3000);
          }
        }, {once: true});
      }
    });
  }
})();
