## Description

Maximize Video is a simple and effective Chrome extension designed to maximize HTML5 and Flash videos, filling the entire current browser tab for an enhanced viewing experience. Unlike ad blockers, it solely focuses on enlarging videos and does not remove advertisements. Users activate it by clicking the toolbar button and selecting the desired video to maximize, with the option to cancel by clicking the button again.

The extension does not guarantee support for every video website but encourages users to report compatibility issues through its GitHub page for prompt assistance and updates. Maximize Video is ideal for users seeking an easy way to enjoy videos in a larger format without navigating away from the tab or webpage.
