Firefox blocks some images in normal mode even when all plugins and add-ons are disabled vs. showing the correct page in safe mode.
On Costco.com Firefox displays only a low resolution (350px scaled up to 680px) image. The 680px image is listed in the page info/media but isn't displayed. Other browsers display the higher resolution image correctly.
Launching Firefox in Safe Mode solves the problem. However, manually disabling all add-ons and plugins and launching in normal mode still doesn't display a higher resolution image. I tried uploading the images to illustrate the problem but the upload hangs with the wheel spinning in perpetuity.
Advice is appreciated.

The first and third screenshot show the the shield icon in the location/address bar to indicate that Tracking Protection is blocking content.
You see the shield icon at the left end of the location/address bar in case content is blocked by Tracking Protection.
- click the shield icon for more detail and possibly disable the protection
- check the Web Console for more detail about what content is blocked by Tracking Protection
- "3-bar" menu button or Tools -> Web Developer

I used that site and have no real issues with FF when accessing it? Can you provide actual screen of the errors that are happening.
As I said, getting errors uploading images. I even tried in the Safe mode. I can email them if you give an address.

Try later. I get timed out when I try to go there. Is US site and I am not in the US.
Looks like the problem is that the files are slightly larger than 1MB limit to upload. Will re-do and upload. Thanks for looking into it.
Here are the screen shots. Notice the low resolution images and missing additional views in the normal vs. safe modes. Disabling extensions and plugins manually (like in the safe mode) does nothing.

Disabling tracking protection seems to make the problem go away. The web console shows the element that is blocked. It almost implies that the higher resolution image is used from tracking.
Thanks for your help!
