When you need to click a link on a web page, you have to place your mouse exactly on the link before the mouse pointer turns into a “clickable” hand.
With bubble cursor installed in Chrome, you can click on links by simply moving your mouse near a link. While the cursor in near a link, the pointer turns into a bubble and you an left-click to open that link.
It also works for typing text inside input fields without you having to highlight the text field. Just bring your mouse pointer near the next field and start typing.
Bubble Cursor, by default, is enabled for all websites but you can click the extension’s icon in the Chrome toolbar to disable it for any particular website.
Alternatively you can go to the options panel and blacklist multiple websites in one go.
