FAQ on Plugins and Add-Ons

This FAQ has been produced to try and address issues caused when using browser add-ons

How this site works: This site tells your browser to try and load several remote javascript files. Each file is on a different server. After each one finishes, we look at which ones worked - and which ones failed. Depending on the pattern, we can guess at IPv4 and IPv6 compatibility, and sometimes suggest possible fixes.

Some browser plugins enforce policies that are compatible with the above behavior. They block connections that (to them) look like they might be 3rd party advertising or tracking. There is no good way to identify this plugins from inside javascript; nor any good way to work around it.

After disabling any suspect plugins or extensions, try this site again. If it still fails, disable all plugins and extensions, until the browser works again. Alternately, consider trying another browser. Suggested browsers: IE, Firefox, Safari, Chrome.

Alternative test for you..

This image based test is provided as a workaround. It will give you a quick pass/fail test, to tell you if you should be worried for World IPv6 Day.

The following table will try and load 3 images.

Pass?	Method	More Info
	IPv4	IPv4. Basic traditional Internet.
	IPv4 or IPv6	If green, you will have no problem on World IPv6 day. If this fails, seek help from your IT department, helpdesk, or ISP tech support. If this fails, consider using the full test, with IE, Firefox, Safari, or Chrome, to get more detailed information about possible failure reasons.
	IPv6	If red or blank, do not stress! Few people already have IPv6 at this time; and it is not critical for 2011 but will be for the coming years.
