Hi. I am Rick and I will be your Computer Expert. I will do my best to assist you with your question.
It basically means the web browser you are trying to use is not supported by the operating system you have. Is this on a computer or an android phone?
Google is not said to work well if at all on an Android. There are 3 browsers below that are designed to work with that phone. They are all free for download and any of them will get rid of your problem. If they do not you need to take the phone back and have someone check it for you because there is something amiss in your operating system but one of these should work for you.
