No labels on Google Maps website when using Firefox
When I enter to the website it shows the labels of the cities, countries and all the elements on the map, until it finish loading, then everything desappears. So, after two second you have the map empty with the icons and roads but no name of city or any other element in it, it only happens when using Firefox.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, Disconnect, Ghostery, Privacy Badger, uBlock Origin), always make sure such extensions do not block content.
- make sure your extensions and filters are updated to the latest version

You can check for issues with Enhanced Tracking Protection and Total Cookie Protection. Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.
- click the shield icon for more detail and possibly disable the protection
You can check the Web Console for relevant-looking messages like about blocked content.
