It's not 100% safe but it does hide your real IP which prevents people from tracking your online activities. Although proxy servers does a good job making sure your online activities are not tracked… there are many other variables which allows a person to track your online activities such as trojans, spywayre, adwares, etc.
Before choosing an anonymous proxy server, try and do a little research. Search on the net and find out whether there are other people using the same proxy server and whether that had any problems with it.
