Why can’t I upload photos to Facebook with Firefox. I can upload photos with Internet Explorer.
You probabaly might not have the Java Plugin installed for Firefox. Facebook uses Java to upload images to the albums of the particular users. Just go ahead and install Java plugin for Firefox. That should work. :)
Hmm, since the uploader uses Java, do you have the latest version of Java for Firefox?
Here's the download page directly from the Java homepage: http://www.java.com/en/download/inc/windows_upgrade_xpi.jsp
Make sure you're also running the latest version of Firefox. The only other option I can think of would be to upload pictures via email (you can find your address at http://www.facebook.com/mobile/).
