The extension allows you to capture any page from your favorite websites such as Facebook, Twitter, Gmail, etc.

The first step is to open the website you want to take a screenshot from. Then you need to click on the extension icon in your browser. This will open a new window with the page you want to take a screenshot of.

After that, you need to select the desired screenshot view and then you can either capture the whole page or just the visible part of the page.

The screenshot will then start downloading at the bottom of the browser window. After a few seconds, you can find the downloaded file in your Downloads folder.

You can open it in any image editor and you can then use it to edit your images or use it for other purposes such as creating presentations.
