Survol for Chrome and Firefox enables a unique timesaving option for searching links, websites, articles, and more.
It works by allowing you to hover over a link, and it provides a preview of the content and eliminates having multiple resource-consuming tabs open at the same time. Not only can this help you with your searches, etc., but it can potentially help protect you since you get a heads up about the content before committing to opening.
Survol is straightforward to use, including next to no settings other than dark mode and the advanced setting for inner links preview disablement. If you spend time looking up articles, etc., for school, work, or personal, this will be a useful extension/add-on.
