Is this centered in a dark background, similar to what you see if you right-click a small image and choose View Image?

Could you check the address bar: does Firefox display the source of the image?

You can check the log in the Web Console for error messages and the Network Monitor (Firefox/Tools > Web Developer).

• https://developer.mozilla.org/Tools/Web_Console
• https://developer.mozilla.org/Tools/Network_Monitor

Use Ctrl+F5 or Ctrl+Shift+R to reload the page and bypass the cache to generate a fresh log.

Yes it is a 1 pixel white dot on a black background URL in this instance = http://click.email.optus.com.au/?qs=c1d4995139d7a97e8730bb9d781e1cfab9967a7cc58f8d7ec9f2e2680f62d75a282ffb0074f97e7f

Ctrl+F5 or Ctrl+Shift+R made no difference

When I open the Web console on the tab with the error, the window at the bottom of the screen is clear - no text at all.

Network monitor shows the file and the domain and a padlock with a red forward slash through it. Do you need any further info?

After opening the Network Monitor, try pasting the problem URL in the address bar and pressing Enter. You've got a tracking link that should redirect, as shown in the attached screen shot. Do you even get that response from the site (with the Location header Firefox is meant to follow)?

yeah tried that - didn't really work, but I don't want to have to do this every time I want to open a link and get this error (which is often), I want to stop getting the error.

Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.

Hmm, I don't know what you mean.

Did your Network Console show that Firefox just got the image, no Location header? That would imply external intervention. Or did it get a redirect and ignore it, which would suggest some kind of internal issue in Firefox or an extension. That's what I'm hoping you can help me figure out.

cor - el Rebooted to safe mode with networking. Could not start Outlook (that is where the link is that brings up the error - in an e-mail), so I went to firefox history and clicked on the Gif image 1 x 1 pixels page, and got the same result.

I have attached a screenshot for you - can you see the answer to the question you are asking

Interesting: we are connecting to completely different servers based on their IP addresses. (Screen shot comparison attached.) Mine's on an Exact Target server, which sounds like an email advertising company, and yours is on the Amazon cloud. I don't know what accounts for the difference.

Did you try to clear the cookies that are send with this request?

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

"Clear the Cache":

• Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

"Remove the Cookies" from websites that cause problems.

• Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"

Ok, I have cleared the cache and removed the cookies as directed above, then I closed and re-opened Firefox and clicked on the link above, and got the same issue.

Also, another anomaly, is that I cannot sign-in to http://www.xbox.com/en-AU/, when I click on the "sign in" link at the top RH of the page - nothing happens. However I can log in to https://www.microsoft.com/en-au/ without any problems. When I do I can go back to http://www.xbox.com/en-AU/ and I am signed in, but when I click on my name the drop-down list does not appear.

I have spoken to XBOX support and they said I need to re-image my PC.

You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History > Show All History" or "View > Sidebar > History") or via the about:permissions page.

Using "Forget About This Site" will remove all data stored in Firefox from that domain like bookmarks, history, cookies, passwords, cache, and exceptions, so be cautious. If you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of the involved files.

If you revisit a 'forgotten' website then data from that website will be saved once again.

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen or hold down the Shift key) to see if that has effect.
