Mozilla Firefox addons or extensions are programs that can be installed into Firefox in order to change the browser's functionality. This includes adding new features or modifying existing behavior in Firefox in order to fix bugs, add extra functionality, or increase the browser's security.
Mozilla Firefox provides an easy to access toolbar at the top of the browser window that contains a variety of icons for popular and commonly used features. As you add new Firefox extensions, though, the toolbar can become filled with unwanted icons. This guide will explain how to remove a button from the Firefox toolbar.
In addition to customizing the buttons on the Firefox toolbar, you can also customize what buttons are displayed in the Firefox menu. This provides easy access to Firefox extensions or other desired features.
If you have previously added some buttons to your Firefox menu, you can just as easily remove them to provide more room for other features.
A new feature in Windows 8 is the ability to use a short video clip as your account picture instead of a static image. This feature, though, does come with some limitations that include videos will only play on the welcome screen and will not be animated on the Windows Start Screen, the videos will be restricted to having 5 seconds in length and will loop continuously, and you will not be able to use any existing videos as your account picture. Instead you must create it via your webcam from within Windows settings. If these limitations do not bother you, then this tutorial will walk you through creating a video and assigning it to your account picture.
Twitter offers a Night Mode that causes the site to display darker colors in both the Twitter Mobile app and on Twitter Desktop, which is when you use a desktop browser such as Chrome, Firefox, or Android to access Twitter. These darker colors produce less light and thus do not bother other people in the room, are easier on the eyes when viewing Twitter in the dark, and arguably look better. This tutorial will walk you through enabling Night Mode in Twitter.
