  • 2011-08-01: We experience an issue that Firefox 3.0 .19 craches when Google Earth plugin is launched. This issue happens on the Google Maps site as well and hence we assume this is a problem with Google Earth plugin and/or Firefox 3.0.19. To avoid this issue, upgrade your Firefox to 3.6 or later or disable Google Earth plugin.
