One Tab Only

This extension makes sure there will be only one tab open for the specified/configured domain URL.

One Tab Only: Maintain Single Tab for Chosen Domain

The 'One Tab Only' is a Chrome extension targeted at giving users clarity and organization while they browse. Upon changing tab URLs, the extension checks if the new URL matches with a predefined domain URL. If a match is found, the extension opens the URL in the pre-existing tab with the same domain, closing the original source tab. Users can define the domain URL via the extension options link. Additionally, the extension offers notifications which can be disabled at the user's discretion.

User reviews

- Only allows ONE url to be stored for matching. - Far too aggressive. Matches as soon as you start typing. And since Chrome remembers URLs you've typed previously and tries to autocomplete, it matches as soon as you type a single letter -- so, you can no longer type OTHER url's beginning with the same letter! Example: If you have "https://www.google.com/" stored and you press "g" (like say, to type ANY other URL starting with a 'g'), it will close the tab and jump back to your open Google tab. I've been looking for something like this, but this extension won't cut it.

does what i need - but only one url is able to be configured. Can we save multiple please?

It works well! But I miss that it does not detect URLs from the same domain that are already open in another window and not in another tab of the same window. Could this be done? :)
