Is "Take and resize browser screenshots" on Chrome Web Store Safe to Install?

USE CASE: You are preparing documentation of a web tool. You need screenshots of the browser window as is. Everything you see, namely the URL in the address bar, opened menus and tooltips triggered by mouse over events, must be visible in the screenshots. A screenshot should be taken, saved and copied to the clipboard in one click. You could do that with Greenshot if having to select the region for each screenshot does not annoy you. With the Snipping Tool you need to click a bit more to save the file. What if the screenshots have to be resized to a specified size to be uploaded somewhere? For example, imagine you are preparing 1280x800 screenshots required for publishing an extension in the Web Store. The 1280x800 screenshots illustrating this extension were taken with this extension. HOW TO USE: - Click the icon to select the screen with the browser window to be captured. The icon becomes green, the extension is ready to take screenshots of the selected screen. - A notification bar appears at the bottom. It is an independent browser window. Click Hide to minimise the bar window. - Open a web page in the browser running in the selected screen.The browser window can be maximized or minimized. The extension captures the screen region of the browser window in which the icon has been clicked. - Click the icon to take a screenshot. Each time you click, the screenshot is downloaded and copied to the clipboard. The file name of the downloaded screenshot is the URL of the page where the icon was clicked. - Keep taking screenshots. Maximize, minimize and move the browser window. - To inactivate the extension, first maximise the screen sharing notification bar by clicking the last browser window, then click the blue Stop sharing button. OPTIONS: The extension works without any additional configuration. If needed, the screenshots can be resized before saving and saved as png or jpeg files. Capture of the screen can be delayed if you need to capture a browser menu or HTML or browser tooltip triggered by a mouseover event. The options can be accessed by right-clicking the extension’s icon and then clicking the Options IMPORTANT NOTE: Regardless of the tool you use, you can capture HTML tooltips, or browser tooltips or menus, only if you capture a screen. That is a constraint by the operating system. Tooltips and menus cannot be captured in a window or tab display surface.

It has no cumbersome popups with pointless options. One click - one file on the disk and in the clipboard - It is free and open source
