Without further details like what site you're visiting at the time, I can't say why you're constantly being asked to share your location. If you don't want to use this feature, you can disable it as follows:

1. Type about:config into the address bar and press Enter.
2. To bypass the warning, press the big button labeled "I'll be careful, I promise!".
3. In the search box, paste geo.enabled
4. In the search results, double-click geo.enabled to set its value to false.

If you get that again, try to get a screen shoot and post it here.

In order to better assist you with your issue please provide us with a screenshot. If you need help to create a screenshot, please see How do I create a screenshot of my problem?

Once you've done this, attach the saved screenshot file to your forum post by clicking the Browse... button below the Post your reply box. This will help us to visualize the problem.

Thank you!
