Professor X for Firefox 3

by Stuart Robertson on August 21st, 2008 | Web Design Software

Following the update to the X-Ray extension is the new version of Professor X for Firefox. While X-Ray lets you see ‘through’ a webpage to the HTML tags inside the body, Professor X lets you see inside the head tag without viewing the sourcecode.

I’ve submitted the update to Mozilla Addons, but I’m not sure how long it will take for that to make its way through the approval process and be made available for download. For anyone who wants to get the extension from Design Meme, here’s the link:

Install Professor X version 0.5

What was interesting with this update was that Firefox 3 now prevents the a webpage from accessing any of stylesheets or icons packaged with the extension through the chrome:// url. This meant changing the approach to how Professor X worked, making all of the CSS part of the javascript file and encoding all of the icons in Base64.

It’s good to finally have both of these extensions working with Firefox 3 (I’d missed having them for my own use!).

    Thank you SO MUCH for updating professorx! I discovered just how much I had been using it when I upgraded to Firefox 3 without it.

    You’re welcome. Nice to see Professor X is useful for you – it’s usually X-Ray that I get feedback on. :)

    Cool, just downloaded it. Nice work, Stuart!

    Out of curiosity, why did you choose that X-Men name for the plugin?

    The first extension was called X-Ray because it could see ‘through’ the BODY of a webpage to show the tags underneath. Professor X can see inside the HEAD of a webpage (kinda like Professor X of the X-Men), plus the X ties the two extensions together as well—since they’re really a set in my mind.

    If I release another extension I’ll likely try and work an X in the title as well, or at least give it a spooky mad scientist theme.
