FF 48.0 is behaving strangely with google maps and I cannot figure out why. The behavior is this: When I zoom in on an area (map view), building outlines do not appear. This is a new behavior that I had not seen previously. When I run in safe-mode, buildings appear as expected. However, when I disable all of the add-ons in my account, the buildings still do not appear. I tried flushing the cache and offline website data, but that did not help. (Clearing the other categories is not really an option - too much valuable information contained therein.) Google maps works properly with IE, thus the issue seems to be localized to this one FF profile. Is it possible that there is a difference in about:config between normal mode and safe-mode and that is causing the issue? If so, how can I track down this difference? What else should I look into? Just tried another experiment: I refreshed a map and the buildings appeared, whoever, after a second or two, they simply disappeared. I then enabled Firebug and refreshed the page. The Console->Errors window showed two items: 23:53:56.415 CSI/tbsd_ 23:53:56.416 CSI/_tbnd When I looked at the Net->All tab, the various images that were downloaded do show the building outlines. I look forward to reading your suggestions.
