1385698 - Empty tab title when restoring text/plain tab with attachment

Status: NEW

(Firefox :: Session Restore, defect, P3)

Description

[Oriol Brufau [:Oriol]]

1. Enable automatic session restore
2. Save this PHP file in a local web server:

    <?php
    if (empty($_GET['foo'])) {
      echo '<a href="?foo=true">Open this link in a new tab</a>';
    } else {
      header('Content-Disposition: attachment;filename=foo.txt');
      header('Content-Type: text/plain');
      echo 'Foo';
    }
    ?>

3. Load that file in Firefox
4. Open the link in a new tab (Ctrl+click or via context menu)
6. That new tab has a title
5. Open browser console and enter this code to restart Firefox:

    var a = Components.interfaces.nsIAppStartup;
    Components.classes["@mozilla.org/toolkit/app-startup;1"]
    .getService(a).quit(a.eRestart | a.eAttemptQuit);

Result: the tab has an empty title

This worked before bug 1360932. Between bug 1360932 and bug 1365933, Firefox was not able to restore the tabs. After bug 1365933 tabs are restore again but the title is empty.

Oriol, is this still happening for you?

Yes, this is still happening with latest nightly.

I usually get tabs with empty titles when I restore the session, not just when following the steps in comment 0, but that's a reliable way to reproduce it.

Not sure if it's related, the browser console shows

    Error: An unexpected error occurred (undefined)

Moving to p3 because no activity for at least 1 year(s).

The last needinfo from me was triggered in error by recent activity on the bug. I'm clearing the needinfo since this is a very old bug and I don't know if it's still relevant.
