Prevent duplicate tabs effortlessly.
Duplicate Tab Helper prevents duplicate pages at the moment new tabs are opened. If a duplicate URL is found, the newer tab will be replaced with the existing tab as seamlessly as possible. The effect is so subtle you may not even notice it happening. Duplicate Tab Helper is FANTASTIC for doing research and quietly makes your browsing experience more enjoyable.
Please note: This extension was built with a keep-it-simple-and-speedy philosophy and it is not designed to stop sites that use bounced URLs such as Google.com or Yahoo. If you want to test that the extension is correctly blocking duplicates, try fooling around on Wikipedia. :)
* In a pinch, you can override the duplicate-closing behavior by opening duplicate URLs in new windows.
* Because some websites forward the URL right after opening, they will not be detected as duplicates. Unfortunately, Google Search is a perfect example of this. Out-of-date bookmarks can also be missed so keep them updated.
* Please note this extension uses extreme caution when detecting duplicates and some will be kept for your safety and positive browsing experience. This may cause some situations where you may think the extension is not working. Don't fret--this extension will help you when it can. Check the Options tab occasionally for a count of duplicates caught. :)
* Duplicate Tab Helper is not intended for web developers who frequently need new tabs to replace the old tabs each time they make a change. I love you guys and gals but this extension will drive you crazy. :)

If you are enjoying my extension please write a review and let others know that it works! Non-technical (but well-meaning) users occasionally rate my extension poorly because they don't understand why in some situations duplicates are not matched.
