I have a MacBook running OSX 10.4, and I'm using Firefox 3.0.9. For nearly every webpage that I open, the error log gives me an error like "Expected (blank) but received (blank). Declaration dropped." This isn't a problem for some webpages, as they'll load fully, but for others, they won't load at all. This is a really frustrating problem, and it just started all of a sudden yesterday. I didn't install a new web browser or any new extensions, and I've done virus and malware scans, and I can't seem to find the problem. Could it be a problem with extensions, or with my system, or perhaps my Internet connection? Any help would be greatly appreciated.
