Prevent duplicate tabs effortlessly.

Description from store
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,
Justin

*** RELEASE NOTES ***
1.4.5
Fixed: Stability while overhauling to Manifest 3
Fixed: Disappearing context menus on right-click
Fixed: Total duplicate count not always syncing
1.4.4 Fixed: Duplicates are no longer matched between incognito and non-incognito ecosystems. This only became an issue when the "all windows" search feature was introduced in 1.4.2.
1.4.3 Tightened up duplicate disposal to only dispose of duplicate after active tab has been set. This is to (hopefully) address a rare bug when opening new blank tabs where focus was not properly put on the remaining tab.
1.4.2 Added option to search all windows for duplicates. No longer checks for duplicates in pinned tabs or in non-"normal" windows such as "popup", "panel", "app", or "devtools". If catching duplicates in these window types is desired please send an email and let me know some specifics.
1.4.1 Under default settings, instead of ignoring "navigation duplicates", duplicates are pulled forward to the same position as the active tab, but no tabs are removed.
1.4.0 Customization options added for how to deal with "navigation duplicates"
2019-06-17 Update 1.3.9: Can now detect duplicate URLs with a hash (#) character in them. Also if you open a blank tab and happen to type a URL that is already open into a BLANK TAB then the duplicate will be matched and handled.
2019-06-16 Update 1.3.7: Disabled notifications. On Windows 10 they are put into a notification center and must be manually dismissed. That's way too much clutter, so I disabled them. Thanks for trying them out.
2019-06-16 Update 1.3.6: Support added for bounced URLs! But only if the tab was opened in the background. I think this is a nice compromise to keep the extension lightweight but still very effective.
2019-06-15 Update: Right-click menu has a 'Duplicate' option in case user really does want a duplicate.

- (2022-09-21) Christoph Rackwitz: stopped working recently... and no updates or any activity for this extension...
- (2021-03-10) Evan Lao: A lightweight alternative of "Clutter Free". Works for me.
- (2021-01-26) Dmitry OD: This app is doing more harm than good. Because when you open a copy of a tab, it is removed from the group. And you need to drag it to the group every time over and over and over again.
- (2020-07-30) Frances Cherman: I love this extension!
- (2019-09-04) Sebastian Jurk: Unfortunately it always closes the tab that is most right. It even shows a popup asking if one wants a duplicate tab but that's useless when it shows up in a tab you aren't in. I would nearly not have noticed that certain tabs are gone while I only opened temporarily some tabs to store something. I will deinstall for now and use it when I need it for certain actions.
- (2019-06-25) Scott L: Developer has been extensively helping me find bugs and improve this software, it has now reached a point of reliability that this is saving me time in my very very mess and poor browsing habit / workflow. While I should probably just 'browse differently' this has done things in a logical manner which is exactly how software should be. If I make a dumb mistake, this is correcting that mistake. Thank you.

- (2018-08-21) davide bronzini: I still can ctrl + click on different Chrome windows and browser opens new tab. If I could have more windows url uniqueness, it would be 5 stars. Good job however
- (2018-03-14) Jason Axley: Didn't really help. I can open the same URL in multiple tabs. Going to try another extension.
- (2017-08-17) Michael Reinhart: It works exactly as described!
- (2017-07-06) Lucas Rangit Magasweran: This works great for me. My solution to the tracking URLs that Google search results use is install the extension "Don't track me Google" ( https://chrome.google.com/webstore/detail/dont-track-me-google/gdbofhhdmcladcmmfjolgndfkpobecpg ). This replaces the unique URL that Google creates with the original.
- (2017-06-08) Emile Sonneveld: Doesn't dedup all websites, but it does it enough to keep my tab list clean.
- (2016-08-10) Rick Feuling: I love the concept but it doesn't work. If it won't with something like google.com it won't work with much. Tried it on Yahoo.com, tried it with Asana - never saw any effect. If the app was improved I'd definitely give it another shot.
- (2016-08-10) Mutt Mingle: Does exactly as described! 5 stars!
- (2016-03-06) Billie Reinhart: Works exactly as described !!! Awesome !!!

- (2015-10-12) Doesnt work. I tried openiing dublicate tabs just for checking purpose and it never did anything to close or avoid opening it.

- (2014-04-30) Keith Tyler: Does not work. Repeatedly opened multiple tabs to exact same url, none were caught at all.
- (2014-02-11) Gordon Pham-Nguyen: Sometimes it works, sometimes it doesn't..
