Change Description

This hides it from both the toolbar and the unified extensions panel.

We also hide the unified-extension-button if the panel would be empty: not including the NoScript button when it is hidden. As a result, this will be hidden by default until a user installs another extension (or shows the NoScript button and unpins it).

How Tested

Check the default behaviour:

  1. NoScript should be hidden from toolbar.
  2. Unified extensions button should be hidden. Even when shrinking the width.

When installing another extension:

  1. Install popups (and other extension popups) will appear beneath the unified extensions button.
  2. New extension will be visible.
  3. If the extension is pinned to the toolbar, the unified extensions button will be hidden (since it is empty). It will reshow when shrinking the window width and the extension button overflows.
  4. If the extension is not pinned, the unified extensions button will be visible.

In "about:config", switch "extensions.hideNoScript". This will make the NoScript button appear (in the toolbar by default for a fresh install).

Switching "extensions.hideUnifiedWhenEmpty" will make the unified extensions button always visible.
