best links previewer extension for Firefox

This is a very useful features for fast searching in web or just curious without opening a new tab!

Just the way trigger press and mouse move is confusing without seeing the extensions itself, but it works!

This is a very useful feature that helps ease disparity between Zen Browser and Firefox!

Thank you so much!

sometime will change the current tab. it would be better to combine with "side view"

Great addon, the best of any of the link preview addons out there.
Very useful, e.g. to avoid opening countless tabs while reading an article. Simply preview the embedded links and only open the ones you actually care about.

underrated extension for firefox. I will buy a coffee for author. thanks.
