Overview

Product summary

Review the store description, core capabilities, and common use cases.

Duplicate Tab Helper prevents the opening of duplicate URLs at the moment new tabs are opened. If an exact duplicate 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.

Unlike other extensions, great care is taken to make sure that when a duplicate is detected and discarded that it doesn't contain unsaved information. There is literally zero instances where this extension discards an old tab that you might have been using (unless you change your preferences.) Sometimes this means a few duplicates are ignored under specific circumstances. In cases of uncertainty, caution is favored over cleanup.

Tips:

* You can still create a duplicate. Right-click any page and select 'Duplicate this tab'.

* 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. :)

Best,
