re: How to tell your employer you are bored in your job

If you have that much free time and management allows you to hide behind your screen, then you need better supervision. I'd seriously start looking for another job, because your current workplace is not well managed and thus will be a dead end for you.

Also be aware that some employers can and do review their employees' internet surfing histories.

Be proactive....can you not think of a single productive thing to do without being directly told to do it? Hell, go tidy the supply closet, or fill the printer/copier with paper, sanitize the phones.....I'd be desperately searching for more tasks as your multitude of free hours does not make you an indispensable employee...it makes you a little needed one.
