There are several times when you might want to use browser only for certain things and not want it to crowd up your taskbar. Instead of closing the application, you can always minimize them to the system tray using several applications including our favorite TrayIt.
If you are a Google Chrome user, you can use a handy Google Chrome Extension called Minimize to Tray, which will allow you to minimize the Chrome to the system tray, and free some space in your taskbar area.
However, there is one problem with this extension. It will always send the application to the system tray, whenever you click the minimize button on the browser. Instead of doing that, the developer could add another button, clicking on which would send the browser to the system tray.
If you do not want to add this behavior to the browser, you can always try out the best application minimizing tool, TrayIt, and use the hotkey Ctrl + minimizeto send the application to the system tray.
