Rated 1 out of 5
by Firefox user 13465535, 9 years agoThis new version is totally useless for me. I need the tool "Display style information" back. Also this change made the whole Firefox totally useless for me. Where I could download the old version of the developer toolbar and old version of Firefox. This is really important and freezes all my work. Used to be 5 star extension, now 1 star. All I can do is star a uninstall process of Firefox browsers from all our school computers and searching a new tool. Sad end for such a great browser.
Developer response
posted 9 years agoThe ‘Display Style Information’ feature had to be removed as Firefox removed the APIs that it was using. The best replacement for this feature is the CSS inspector built into the browser developer tools:

Older versions of the extension are available here, but note that they are not supported and will not work in future versions of Firefox:

- Rated 5 out of 5by skevil, a month ago2026 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.

- Rated 5 out of 5by amcginn, a year agoThis 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.
