Why my desktop FireFox Quantum suddenly displays Amazon site in mobile screen style?

Firefox has started displaying Amazon pages in mobile mode, i.e. everything grouped horizontally and stacked vertically. Amazon has no glue why. I'm running latest version of FF, 58.0 on 64 bit win7. I find nothing in settings regarding the style of display. Anyone seen this behavior before. It is only the Amazon site that is doing this. Thanks!

Chosen solution

Clear the cache and remove the cookies from websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).

"Clear the cache:

  • Options/Preferences -> Privacy & Security -> Cached Web Content: "Clear Now"

"Remove the cookies" from websites that cause problems.

  • Options/Preferences -> Privacy & Security -> "Use custom settings for history" -> Cookies: "Show Cookies"

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window

I use and installed FF58 and use Amazon as well. But I don't see the screen your seeing. So can you post what it looks like so others can test if Amazon on their side does it or not.
