Highlander is a Firefox add-on that limits the number of tabs for each URL to one, preventing clutter and simplifying internet navigation.
While this feature can be helpful, it may not work smoothly with sites that heavily use JavaScript. To address this, the extension provides a whitelist of URLs that won't be affected by the switch-to-tab feature. Additionally, the extension can be disabled with a simple click of a button.
The whitelist feature is particularly useful as it supports wildcards. You can use the * character to represent any character zero or more times. This allows for more flexibility when setting up your list of whitelisted URLs.
To use this extension, you'll need Firefox 2.0Beta1 or later. Overall, if you want a more streamlined browsing experience with less cluttered tabs, this extension is definitely worth giving a try.
