Bulk Trash by URL helps editors and SEOs quickly clean up content by trashing items based on a list of URLs. Paste your URLs, let the plugin map each URL to a post ID (handles common variations like trailing slashes and marketing query params), select what you want to remove, and process in efficient batches with progress feedback.
Key features:
<ul>
<li>Paste URLs to find matching posts, pages, and custom post types.</li>
<li>Fast URL-to-post mapping in AJAX batches with progress bar.</li>
<li>Select exactly which items to trash before running.</li>
<li>Batched trashing with live progress, pause/resume controls.</li>
<li>Optional completion summary with counts and lists (trashed, failed, no permission, invalid).</li>
<li>Settings to tune performance and limits:
<ul>
<li>Max Page Size (mapping batch size)</li>
<li>Max URLs per run</li>
<li>Toggle completion summary</li>
<li>Optional mode to set matched items to Private instead of Trash</li>
</ul>
</li>
</ul>
Built for large lists and long-running jobs. Everything goes to the WordPress Trash, so you can restore or permanently delete as you normally would.
Capabilities & security:
<ul>
<li>Restricted to users who can <code>manage_options</code>.</li>
<li>Nonce-protected AJAX endpoints.</li>
<li>Conservative sanitization and server-side validation.</li>
</ul>
Compatibility notes:
<ul>
<li>Works with sites using pretty permalinks. Mapping relies on WordPress <code>url_to_postid()</code> and common URL variants.</li>
<li>Custom post types are supported if they use public, front-end URLs.</li>
</ul>

If you use the WordPress admin area on a mobile device, or have cats sometimes walk across your keyboard it can be good to have a fail-safe confirmation before permanently deleting posts from the Trashed items. 
This plugin adds simple JS to the admin area to do just that.

Trash Fail Safe

Require confirmation before deleting items from the Trash, or emptying the whole Trash. Protects against accidental clicks.
