If you want to manualy do this, you can use a trick that i use with some browsers installed in my web servers.
1) Use IE,Firefox,Opera or Safari
2) Depending which browser you use, go to Tools or Edit or preferences
3) Search Privacy and chose to block all cookies and to ask you if you want it to accept them
4) Enter inside the website you want, and you will notice a pop up window prompting you to accept the cookie of some website
5) You can acept one at a time, Note each address of each of this web sites
6) Go to the Tools of your browser and search the security zone and go to the restricted web sites and write each one of them (you do not need to write all the address, only the root of each one EG: www.adsmakingmecrazy.com)
If you have problems accesing the website, go to tools --> privacy and see if you are blocking by error some website that is not an ads website, any question, send me a message
