Anyone well versed in internet browsers knows the art of opening new tabs. In some cases, people maintain a dozen or more open tabs on their browser, which keeps the CPU working hard and slowing down the browser as a whole. For Firefox users, the new BarTab Lite X extension can help to avoid this problem altogether.
Using this extension, simply right click on the tab and unload it. Doing this will keep the tab open in the browser, but without slowing down the browser. For prolific readers, procrastinators, and savers, the BarTab Lite X extension can be a real life saver. While it is for Firefox users only, there are many similar types of programs being created for other browsers as well.
