particular sites not working after 8.1 update

[Frank Williams]

Hi i have the Lumia 520 and updated to 8.1. Very nice update until sites i used to visit now dont work or have pop ups that stop me from using the sites. I had none of these problems before i updated to 8.1. Can i reset phone to go back to old 8 only as i use the sites more often for them to not be working.
