Cool Previews is a handy extension for Mozilla Firefox that allows you to preview websites before clicking on links. Simply hover your cursor over a link for a second, then move it to the small Cool Previews icon that appears. A tiny window will open, giving you a sneak peek of the site. While you can't browse the entire webpage, you can see enough to decide if you want to visit it. This feature is particularly useful for avoiding malicious websites and ensuring the content is what you expect. However, please note that Cool Previews is no longer being updated and may not be compatible with future Firefox versions.
I’m on the fence about this app. Some features work perfectly, like the fast previews, but I’ve had my share of bugs. If they can fix those issues, I might change my mind!
