See <a href="https://yobukodori.github.io/freedom/image/cors-for-me-screenshot.jpg">the screenshot</a>.
<ul>
<li><strong>Enable at startup</strong>: Enable this feature when the browser is started. </li>
<li><strong>Print debug info</strong>: Output debug information at the bottom of the Options tab. </li>
<li><strong>Theme</strong>: Select a color theme for the settings page. As soon as you select a theme, it will be reflected in the settings page, but only temporarily. Apply or Save as needed.</li>
<li><strong>Applied URLs</strong>: Comma-Separated target <a href="https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Match_patterns">URL patterns</a>. Allow cross-domain xhr requests to these URLs.</li>
<li><strong>User-Agent</strong>: (Optional). Sets this value to User-Agent header.
Setting user-agent header in xhr causes preflight OPTIONS request. And some sites deny the request. In such cases you can set this option to avoid preflight request.</li>
<li><strong>Save</strong>: Save and apply settings.</li>
<li><strong>Apply</strong>: Apply settings. (doesn't save settings).</li>
<li><strong>Get Status</strong>: get current status and applied settings.</li>
<li><strong>On</strong> enables this feature. <strong>Off</strong> disables this feature. Or clicking the crossing arrows icon in toolbar will bring up a pop-up menu where you can turn it on/off and open the settings page. </li>
<li><strong>Clear Log</strong>: Clear log.</li>
<li><strong>Export Settings</strong>: Export settings to the file. It is the currently applied settings that are exported, not the saved settings.</li>
<li><strong>Import Settings</strong>: Import and apply settings from the file. Do not save.</li>
