This is a descriptive label of the button for screenreaders and other accessibility tools; it is not displayed by a regular web browers. If the button had a text label, this is what it would say.

The button lets a source cycle through generated codenames like "unelected squash collision glutton guileless unplowed lunchtime"; if they don't like the codename, they can click it to generate another one.

This change was made as part of supporting use of this dialog when JavaScript is not enabled (in which case it would take a lot of redundant HTML to include the username for each row).

This is a hidden menu label for screen readers and other accessibility tools. It is not a confirmation message - it's permanently associated with the language selection dropdown to indicate which language has been selected. Here's what it looks like in HTML:

<section class="menu" aria-labelledby="locale-menu-heading">
  <h2 id="locale-menu-heading" hidden>
    Selected language: Deutsch
  </h2>
  <label id="locale-menu-trigger" for="menu-1-checkbox" class="menu__trigger" aria-hidden="true">
    Deutsch
  </label>

Are we addressing the user or is this an option title?

The former version with [username] was better in the sense that the username is gender neutral, whenever "user" is not.

Is this "The language had been selected" or it introduces the selected language, e.g., "Selected langguage French"?

Shouldn’t these rather read:It is recommended to use Tor Browser to access SecureDrop:?

Yes, {designation} is resolved to the two-word journalist designation for sources, such as "benevolent artichoke" or "humorless musicology". This is an ARIA attribute that is used for screen readers.

Is "{designation}" the name of what we want to unstar?
