My own Google Map icons are not visible in Firefox 8

I have many Google Maps on my website and they contain both default Google icons and my own icons, each with their own URLs. They work correctly in all other browsers, and Firefox 7. However, yesterday I loaded Firefox 8. In Firefox 8 the Google default icons are still visible but my own icons are now invisible, but their placeholders are still there. They are still visible in other browsers. Also, if I now try and add one of my icons to a map, the process seems to work correctly, including a placemark name appearing, but the icon is invisible. The invisible icon is definitely there because you can click the placemark and be taken to the correct position on the map for editing, but the icon is not visible.

Re: My own Google Map icons are not visible in Firefox 8

Which items do you mean?

Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot and make sure that you do not exceed the maximum file size (1 MB).


If images are missing then check that you aren't blocking images from some domains.

  • Check the permissions for the domain in the current tab in "Tools > Page Info > Permissions"
  • Check the permissions for all sites on the aboutSmiley Tongueermissions page, via the location bar.
  • Check that images are enabled: Tools > Options > Content: [X] Load images automatically
  • Check the exceptions in "Tools > Options > Content: Load Images > Exceptions"
  • Check the "Tools > Page Info > Media" tab for blocked images (scroll through all the images with the cursor Down key).

If an image in the list is grayed and there is a check-mark in the box "Block Images from..." then remove that mark to unblock the images from that domain.

Make sure that you do not block third-party images permissions.default.images

There are also extensions (Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images.

Thanks for your suggestions.

I have checked all permissions you suggested - everything seems to be in order.

The problem is all to do with icons that I have made and put into Google maps - default icons supplied by Google all work. My own icons all show on all other browsers, including FF7 - the problem is only in FF8.

I have attached two screenshots, one showing a Google map page in Chrome. Note there are 6 icons showing; Placemark 1 and Placemark 2 are my own icons (which show the works "Start" and "Finish" on the map, and Placemarks 3 to 6 are default Google icons.

The second screenshot shows the same map in FF8. The default icons are visible , but my own icons are not, even though they are still there - you can see they are still there because the Placemark 2 box is pointing to where the icon is in the Chrome screenshot.

Re: My own Google Map icons are not visible in Firefox 8

There is something seriously going wrong with the start.png and finish.png images.

On the about:cache page they have a mysterious cache entry prefixed with "anon&uri=" and produce an error in the Tools > Error Console when I check them in Tools > Page Info > Media

key: anon&uri=http://walkinginfrance.info/icons/start.png
key: anon&uri=http://walkinginfrance.info/icons/finish.png
Error: uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [imgIRequest.image]"  nsresult: "0x80004005 (NS_ERROR_FAILURE)"  location: "JS frame :: chrome://browser/content/pageinfo/pageInfo.js :: makePreview :: line 849"  data: no]

The HTTP response Headers look quite normal to me:

HTTP/1.1 200 OK

Accept-Ranges: bytes
Content-Length: 3486
Keep-Alive: timeout=5, max=100
Connection: Keep-Alive
Content-Type: image/png

The images do load normally if I paste the URL in the location bar.

Thanks.

There definitely is something seriously going wrong with the start.png and finish.png images, but only in FF8, and I have no idea what it is.

Firefox 10 (Aurora) and Firefox 11 (Nightly) have the same problem.

Maybe someone at the mozillaZine Web Development/Standards Evangelism forum can help you wit this problem.

Re: My own Google Map icons are not visible in Firefox 8

I am having the same problem. I stupidly spent quite a bit of time messing with it before I tried another browser, where they work fine.

Man I hope this is being looked at. I have some custom maps and I'm sure people are going to the website in FF8.

Thanks

I don't know what the cause is in keith13 case. Maybe it is a cross domain security issue with that Google script because loading the images directly works. You may need to let the server send special headers in such a case.
