Cross-Origin Resource Sharing issue

I would like some help in one CORS issue.

I have one laptop that I use in home and at work, and right now when I use it at work I have some issues like this:

Font from origin '.....' has been blocked from loading by Cross-Origin Resource Sharing policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '......' is therefore not allowed access.

This result that I can't view websites correctly, because many font are missing. At start I was thinking that was a problem of the internet at work, but then I tested my tablet and smartphone both at work, and it works fine.

So I suppose that can be an issue about my settings network in my computer, but I have no idea, where and how to fix it.

Any help will be much appreciated. Thank you, Ricardo
