Hi there. I have heard that it is completely safe to do this stuff because of my own and personal privacy as it is also good to keep Yahoo cookies blocked because of PC security. Now, after I did that, I just can’t access Yahoo inbox anymore. I am getting cookie error related message every time I try to log in. I didn’t realized that I will be this much safe after disabling the cookies…
This is just not cookie related problem. When you disable the cookie (this is the file that stores information about your account and saved form from particular server), you actually delete them, but as soon as you connect to the Yahoo web site, the file will be recreated again. This is just not good practice for webmail services
