View Multiple Link BGs

View Link Background ImageHave you ever right-clicked on a website graphic in Firefox expecting to find that handy “View Background Image” context menu item only to realize it wasn’t there because the element you right-clicked on was a link? No? Well it happens to me all the time. A little over a year ago I made a little Firefox extension to add that functionality for links.

Ever since Firefox 3.6 came out though, my little extension has been broken. I had no idea why until I dug into the JavaScript and discovered that Firefox was returning the CSS background image URL as url("imageurl") instead of url(imageurl). Stripping the double quotes was an easy fix but I also knew that FF 3.6 supported multiple backgrounds. Out of curiosity I set up a little html link styled with 2 background images and to my surprise getPropertyValue("background-image") returned url("imageurl1"), url("imageurl2"). Sweet! A few more lines of JavaScript and not only did the extension work again, but it works on links with multiple background images!

Now for the sad part…

As I was experimenting with multiple background image support in Firefox 3.6, I discovered that the “View Background Image” context menu item is now missing when you right-click on elements that have multiple backgrounds. While the extension update adds the ability to see all the backgrounds applied to a link, Firefox itself lacks the ability to do the same for other elements. I’m sure I can take care of that with another extension update. For now though, I’m just happy to say it works again.
