Hi all. The website https://www.mapquest.com/directions is not working with Firefox 50. The web page loads however the map does not load and the buttons Get directions and Find places do not function. I am running Windows XP SP3 and its not platform specific as Opera web browser does work well on this website. From what I have heard Google now owns MapQuest. Can someone check to see if their Firefox works with this website ? I do not get a prompt about allowing flash to run so I don't know if this is flash, java, or code related. Any feedback would be apprecuiated and if there is anything I can do to help please give me a shout. Thanks

Hey I did the about:config and geo location was false. I changed it to true closed browser opened browser and mapquest loaded all images and a prompt came up in Firefox asking if I want to share my coordinates.

In lieu of the fact that this is google now I can see where this is all going as far as harvesting IP and other technical info about you. If you dont let us spy on you we disable the page based upon your preference of privacy.

Oddly enough google maps still functions with geo location disabled. Can this mean that google maps can bypass your geo location preferences ?

I never messed with permissions in Firefox but curious to see if page will be disabled if you deny :access your location" ?

Thank you for the input as it did work. User preferences.

It's slow, but I do get a map to display. Have you tried "the usual"?

When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.

(1) Clear Firefox's Cache

See: How to clear the Firefox cache

If you have a large hard drive, this might take a few minutes. If you do not see the number going down on the page, you can reload it using Ctrl+r to check progress.

(2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:

  • right-click (on Mac Ctrl+click) a blank area of the page and choose View Page Info > Security > "View Cookies"
  • (menu bar) Tools > Page Info > Security > "View Cookies"
  • click the padlock or "i" icon in the address bar, then the ">" button, then More Information, and finally the "View Cookies" button

In the dialog that opens, the current site should be pre-filled in the search box at the top of the dialog so you can remove that site's cookies individually.

Then try reloading the page. Does that help?


If problems persist: Could you test in Firefox's Safe Mode? In Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is not running: Hold down the Shift key when starting Firefox.

If Firefox is running: You can restart Firefox in Safe Mode using either:

  • "3-bar" menu button > "?" button > Restart with Add-ons Disabled
  • Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement?


Also, be aware of possible content blocking by Firefox's tracking protection feature if you're using private windows. This article has more information about the "shield" icon you would expect to see to the left of the address in the address bar, and how to make exceptions: What happened to Tracking Protection?.

Tried the safe mode and still no luck. Same problem on Linux with Firefox. From what I hear mapquest is owned by google.

By any chance, did you globally disable geolocation? You can check that here:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.

(2) In the search box above the list, type or paste geo and pause while the list is filtered

(3) If the geo.enabled preference is bolded and "user set" to false, double-click it to restore the default value of true


You can still block Firefox from providing detailed location information using site-specific permissions, either using the panel that drops down from the address bar when the site requests that information, or using the Permissions panel of the Page Info dialog.

You can call that up using any of these:

  • right-click a blank area of the page and choose View Page Info > Permissions
  • (menu bar) Tools menu > Page Info > Permissions
  • click the padlock or "i" icon to the left of the site address, then the ">" icon, then More Information > Permissions

Scroll down to "Access Your Location" and you can uncheck the "Use default" box and select the permission you prefer. (There's no save button, it's saved as you make changes.)

Hi chiselbeak, websites always get your IP address. Otherwise they wouldn't know where to send the responses to your requests. That is the basis for locating you generally within a town or neighborhood, depending on what the data providers have compiled (information which sometimes differs from one service to the next). For example: https://www.iplocation.net/

What Mapquest is requesting your permission to share is highly specific location information that is extremely localized. For example, if you grant permission, Firefox may poll Windows for your nearest wi-fi hotspots (assuming your computer has a wi-fi adapter enabled) and send that information to Google to check against its huge database (compiled using its StreetView vans and who knows what other methods) to pinpoint your location within a range of a few buildings.

Since most sites can work with a zip code or a pin you drop on a map, it would be the rare site where you would approve sharing that detailed location information. And if you do it accidentally and need to revoke it, please refer to my earlier post about using the Page Info dialog.

The reason I think Mapquest doesn't work with geo.enabled=false is that its load process completely halts when it is unable to even request permission. It obviously doesn't require permission, but its design seems to be intolerant to that scenario.

Yes websites will always get your IP address which allows others to identify who your ISP is and they already know what your geographical location is because of your service provider.

I always thought the geo location was to prevent ads spamming you within your geographical area and this is what is financially driving mapquest now. You will see how many ads are running as you provide info about yourself.

Anyway thank you for your help and have a good evening.
