Whenever I try to load a website beginning with stk.co (e.g. stks.co/q1CqL ) Firefox gives the following error message:

The HTTP header field "Accept" with value "hc/url;*/*" could not be parsed.

The same URL loads easily in Internet Explorer and other browsers.

How can fix this and/or configure firefox to load this url?

Thanks!

You might have the "Accept" header customized from the default. Here's one place to check:

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

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

(3) If the network.http.accept.default preference is bolded and marked as user set, it has been modified from the default.

You could right-click > copy the preference and then paste it somewhere for safekeeping -- in case there is a good reason for it being customized, then right-click > Reset it to see whether that helps.

If it has not been modified from the default, one of your extensions or a proxy service may be modifying it on the fly.

stk.co doesn't load at all, and stk.com redirects to agi.com.

e.g. stks.co/q1CqL

The link works fine for me. It goes to tinyurl.com, then to traderfeed.blogspot.com. I'm using Firefox 35 on Windows 8.1.

Just for documentation, here's what I see in the Fiddler debugging proxy for this shortened URL:

Jefferson,

Wow, thanks!

You hit the nail on the head.

Reset to default. Works fine now. I'll keep an eye out for something that alter it in the future.

Thanks again.
