If you want to add a little personalized touch to your profile, maybe you should try using Windows IMacros for Firefox. With this type of add-on, you can add any file that you download to your Firefox profile. These files are then processed by the add-on so that they get added as well to your Firefox profile. When Firefox displays this information, it's done automatically and no one has to know about it except you.
After you have installed the software, you'll be able to try it out for 30 days with a free trial. The free trial allows you to log in and check on the activities that you have done on your browser. If you like what you see, you can purchase the software, which will allow you to upload up to four profiles that you can use to link to each other.
You can also purchase the software so that you can use it all year round. These add-ons allow you to customize Firefox for your profile to be as unique as possible, so no one else can look at your information and guess what you look like. All of your saved downloads are synced, so that they will be available for you no matter where you are.
