Windows 7: Help with a cloudflare problem.What is it?

So an hour or so ago,I switched my pc on for the first time since this morning,So I opened Firefox and proceeded to a usual website that I use and it opened as to be expected.But when I went to open a new tab to go to Ebay,there was a slight delay,and then this popped up on the screen.





But it will allow me to open bookmarked pages or a cached page it will open as usual.It is only when I open a new tab and it is not bookmarked or cached.It also only happens when I try to do a search on the main search bar,and not on the main page or the little mini Google search bar to the top right of the page,also only with Firefox.It happens to all sites and not just Ebay.
Nothing was installed before or after shut down this morning,it literally happened as soon as I tried to use my browser for the first time this afternoon.I've gone into settings and there is nothing out of the ordinary listed there,the same goes for control panel/programs.
I'm at a loss with this please help.Thanks for reading.

Hi there,

It looks like that "usual website" you visited is down....

It is happening with every website.Sorry may bad forgot to mention that.

Then it looks to be your DNS servers. Have you tried changing them?

Try a new profile and see if it works.
Firefox - Create and Run Multiple Profiles

That done the job.Thanks buddy.

You're Welcome

I'd just like to quickly point out, that "unusual website" is eBay, D3LL.
