Extension summary

** Automatically detect and close duplicate tabs

Preventing and closing duplicates tabs is the core mission. The extension runs in the background, checking when tabs are opened or links are clicked to see whether the target webpage is already open. If open, the extension switches focus to the existing tab, instead of opening a duplicate.

NEW: Quick Tab Search - search, switch to and close tabs. (Similar to ‘Go to tab’)

NEW: List all duplicate tabs, close them directly from list.

Tune the core functionality using options - add websites or domains to allow-list to allow duplicates, or use the block-list to only block duplicates on certain websites.

*****USER BEWARE***** Unusable unless you don't need to use it. Your RAM usage will increase until full, drop down, then repeat, over & over with this extension enabled. In a system with over 200 Chrome Tabs Chrome was completely unusable, had to go into the Chrome `C:\Users\<YOURUSERNAME>\AppData\Local\Google\Chrome\User Data\Default\Extensions folder & delete the recently created folder to get into Chrome. On another system with only 30 Tabs I was able to scroll task manager but there'd be multiple minute pauses between when you scroll & when you see it scroll on the screen. It completely filled the 8GB of RAM on this system, then would drop back to only 1.5GB used, then fill up, over & over with no other programs running & only 30 tabs open.

As others have said, the extension isn't working as well as it used to. While I don't have the issue with it slowing down that others report, it appears to have stopped working with Google Docs. Since I work at an organization that relies on Google Docs this is less than optimal as I end up having the same document/spreadsheet/presentation open in multiple tabs and keep opening versions and new tabs.
