I'm using Firefox 10.0.1 with no add-ons or extensions. A few months ago (possibly with a Firefox update?) the markers (the upside down teardrop shaped ones) stopped appearing in Google Maps. I can see that the image "tries" to load there (I see a little square, possibly with the "broken image" icon, flash where it should be), but the markers don't load. I can see the bubble, but no marker.
I've attached an image where you can see the bubble but no marker.
This makes viewing multiple locations on the same map basically useless. Unfortunately I can't test other browsers since this is all I can use at work.
Why aren't these markers showing up and what can I do to fix it?
