LinksWatched Notifies You When Duplicate Tabs Are Opened In Firefox
Duplicate tabs i.e. the same URL opened in more than one tab clutter your browser window unnecessarily. Duplicate tabs are mostly opened by accident or forgetfulness, and rarely out of necessity. We tend to open some of our most frequently used sites multiple times because we forget we already have them open in a different tab, or we can’t find them. LinksWatched is a Firefox add-on that helps fix both these problems; it alerts you when you open a duplicate tab by adding a red border inside the window when a duplicate link is opened, and giving you a desktop notification alerting you that you've opened a link that’s already open in another tab, with the option to switch to it. Compared to extensions like Prevent Duplicate Tabs for Chrome that just close the duplicate tab, LinksWatched doesn't dictate what is done with the duplicate tabs, so the control stays with you.
