Why can't I order anything with a size from amazon?

Windows7 on a sony laptop, no problem with bing. Let me try google.
That worked too, no problem with either one.

For a while this used to happen to me when using Firefox on a Windows desktop computer. Order forms for certain vendors would work for me only when I switched to Internet Explorer. I believe it was a problem with the sites’ software and not with my computer.

Most vendors seem to be more generally compatible now, but I still run into this now and then. When that happens, I usually just phone in my order instead of wrestling with the software.

You could have a corrupted file, not a virus, not something you did, but a file or files that are corrupted could prevent this. Your husband’s computer worked, so it is not the browser.
Do this: Uninstall Firefox. Re-install Firefox and go through that procedure again.

Do you happen to have the same browser extension installed in all three browsers?

If not could you try making a new user account? Then try from that.

Knowing if it is just your account or something system wide would help troubleshoot the issue.

Could it also have something to do with cookies?

@Jeruba :: Unlikely. Cookies aren’t shared between browsers.

Thanks, all. I’m going to check out @johnpowell‘s links as well as uninstall and reinstall Firefox.

It’s just so frustrating because I can order anything else, just nothing with a size!

@johnpowell, maybe I’m not understanding the problem here, but I suggested cookies because I thought she got different results on different computers even though they were using the same browser. If there were certain cookies on her system and not on her husband’s, couldn’t that affect interactions with vendor sites?

She tried three different browsers on the same computer with the same result. Amazon uses Javascript to change sizes. But even with Javascript off it still works. You just have to click a button to reload the entire page.

So I am thinking there is some sort of Malware at play here. Making a new user account makes it so we can see if there is a problem with her user account (which can happen easily) or system wide problem which probably asked her for a password to infect.

I didn’t have time to do that yet, but should be able to tonight. This has been going on for a few months, and in that time I have done virus scans that showed no issues. (Intego virus software, for whatever that information may be worth.) I will be annoyed if it hasn’t picked up some kind of Malware!

Hello tedibear,
Everyone in my office had this exact same problem and I stumbled across your post. I’ve now fixed it and thought I would share the cause in my case.

My office is running a commercial level firewall and on this firewall I have an http proxy – it was the settings in this proxy that was blocking amazon from changing sizes. When Johnpowell mentioned that amazon site uses javascript to change the sizes this got me to thinking that my proxy was blocking javascript. After some investigation I found that the amazon site isn’t using ‘proper’ MIME types so allowing the javascript MIME types though the proxy wasn’t working.

The MIME type amazon uses is :

application/amazonui-streaming-json

Once I allowed this through my firewall/proxy the sizes started to change.

So in your case if you are not behind a firewall that can block based on content type (MIME types) then you should look at your firewall/router or any security software you may have installed. You may need to tell them to allow amazon.com through if you can’t edit these specific settings.

Hope it helps.
