Fantastic plugin but…

Plugin isn’t showing the toolbar link in the latest version of WP now 🙁

by Basil Hendroff

A must-have plugin

I went from an F/E rating to an A/B rating using this tool to help point me to areas on the website front page that were contributing to noticeably slow loading times.
