2026 and still great—one of the select few Firefox extensions I allow to have pinned to the toolbar which tells you this is truly a 5/5⭐ extension.

This is probably my longest-used add-on over the decades I've been using Firefox. It's always the quickest and easiest way to get the information you need about a page—from anchor links to content sizes and more.
