Most modern browsers come with a decent security profile. However, they must be competitive with other browsers and lean towards giving you the best out of the box experience rather than the most safety, so it is possible to increase the security a bit more than the default settings. This site will help you configure your web browser for safer internet surfing. Unfortunately the descriptions are for older versions of browsers you are using so please use it to become generally familiar with the settings available to you for increased security. There really aren't that many settings so it is worth taking a little time to learn about your options. Some of the settings recommended might make your life more annoying than they are worth, like prompting for each cookie, so feel free to back off on that a bit to something reasonable. The point is to be aware of your options and find a good balance.
