Over the past few weeks my toolbar had disappeared. I could still get to the developer tools from the Tools menu but the “one-click” love of the toolbar was gone.

I tried Googling and found nothing so I did what any experienced developer does…guess.  I went to the Firefox toolbar customize tab and reset the customizations to the default settings and, voila! my toolbar appeared again.

Turns out it was there all along it just was not displaying icons or text…doh!

Anyway, if anyone experiences the same thing I did and tries to Google “firefox web developer toolbar missing” maybe you’ll hit this page and find the answer.
