Keep your tabs tidy, so you can stay focused. TabCloser eliminates those pesky leftover tabs from Asana, Discord invites, Figma files, Linear, Notion, Slack, Spotify, VS Code Live Share, Webex meetings, and Zoom meetings—leaving you with a clean browser and a clear path to productivity.
By default, Asana, Discord invites, Figma files, Notion, Slack, Spotify, VS Code Live Share, Webex Joins, and Zoom Joins are enabled. Just deselect any service that you don't want tabs to close for automatically. You can also change the interval that TabCloser uses to close a new tab once a new tab has been opened, by default it's 15 seconds + 5 second new tab buffer = 20 seconds. The New Tab Buffer ensures TabCloser has enough time to detect a new tab and a URL if you're manually copy + pasting a link into a new tab.
Let's breakdown how TabCloser decides if it should close a tab. TabCloser is using regular expressions to look for a partial match on a dedicated URL for each service.
Here's how TabCloser is handling URLs for each service:
^: The start of the URL
https?://: This will match "http://" or "https://"
([a-z0-9-]+\\.)?: This isn't included in each service, but it's to detect a subdomain, followed by a dot "."
example\\.com/: This matches the primary URL of a particular service
For Asana, TabCloser is using ^https?://app\\.asana\\.com/-/desktop_app_link\\?.*.
The app.asana.com/-/desktop_app_link? designates that an Asana link is being redirected to the native Asana client. .* will match any string that follows the ?.
For the "Authorization Successful" page of the AWS IAM identity sign
in flow, TabCloser is using
^https://[a-z0-9-]+\\.awsapps\\.com/start/user-consent/login-success.html
It only matches on secure connections, as that page would never be served over a non-secure one. The domain [a-z0-9-]+.awsapps.com should capture any AWS organization (the subdomain), and the regex only matches on the login-success.html page to make sure login errors would not be hidden from you.
For Discord, TabCloser is using ^https?://discord\\.com/invite/.
The /invite/ is associated with a Discord invite which can be opened in the Discord desktop client.
For Figma, TabCloser is using ^https?://(?:www\.)?figma\.com/file/
The figma.com/file designates it is a file URL. TabCloser will not close tabs for Figma Community profiles, templates, plugins, ..etc. Only file URLs can be redirected to the Figma desktop client.
For Linear, TabCloser is using ^https?://linear\\.app/.*\\?noRedirect=1$'
The \\?noRedirect=1$ designates that the URL was successfully redirected to the Linear desktop client.
For Microsoft Teams, TabCloser is using ^https?://teams\\.microsoft\\.com/dl/launcher/.*
The teams\\.microsoft\\.com matches the domain "teams.microsoft.com.". /dl/launcher/ is looking for the Teams launcher page that givesm you the ability to download, use the web app, or launch in your current Teams install.
For Notion, TabCloser is using ^https?://www\\.notion\\.so/native/.*&deepLinkOpenNewTab=true
The ^https?://www\\.notion\\.so/native/ designates that it's being redirected to the native client. The .* allows for any string of content after the base URL. Then TabCloser is looking for an exact match on &deepLinkOpenNewTab=true to make sure the redirect was successful.
For Slack, TabCloser is using ^https?://(?!(app\\.slack\\.com|slack\\.com|api\\.slack\\.com|.*\\/(customize|account|apps)(\\/|$)|.*\\/home(\\/|$)))[a-z0-9-]+\\.slack\\.com/.*$
(?!(app\\.slack\\.com|slack\\.com|api\\.slack\\.com|.*\\/(customize|account|apps)(\\/|$)|.*\\/home(\\/|$))) is a negative lookahead assertion, that specifies what should not follow the previous part of the regex. app\\.slack\\.com excludes URLs starting with "app.slack.com" to make sure the web client can successfully stay open. slack\\.com excludes the base Slack website. .*\\/(customize|account|apps)(\\/|$), api\\.slack\\.com excludes URLs starting with "api.slack.com", .*\\/home(\\/|$) exclude URLs containing '/customize/', '/account/', '/apps/' or /home either followed by a slash or the end of the string—this is to avoid TabCloser from closer in-browsers settings and config pages for Slack.
For Spotify, TabCloser is using ^https?://open\\.spotify\\.com
The open\\. portion is typically associated with opening a song, artist, playlist, ..etc which can be opened in the Spotify desktop client.
For Live Share, TabCloser is using ^https?://vscode\\.dev/liveshare.
The /liveshare/ is associated with the Live Share URL which can be opened in the VS Code desktop client.
For Webex, TabCloser is using ^https?://([a-z0-9-]+\\.)?webex\\.com/wbxmjs/joinservice.
The webex\\.com/wbxmjs/joinservice is associated with the join meeting URL which can be opened in the Webex desktop client.
For Zoom, TabCloser is using ^https?://([a-z0-9-]+\\.)?zoom\\.us/j/[^/]+#success$
The ([a-z0-9-]+\\.)? and looking for zoom\\.us/j/ as a designated join link, and then looking for #success when a Zoom link is successfully redirected to the Zoom desktop client.
TabCloser requests a few permissions in the manifest.json file.
chrome.tabs allows TabCloser to interact with your tabs, giving it the ability to run when a new tab is detected and if a matched URL is found, close that tab automatically.
chrome.storage allows TabCloser to save your enabled or disabled auto close preferences for a particular service and saves the interval you've set for closing tabs from the options menu.
TabCloser runs completely locally in your browser. It does not collect any analytics, it does not store any information about your tabs or browser history, it does not send any data back for processing or analysis. Your data is yours and yours alone.
TabCloser is available in the Google Chrome Web Store, the Microsoft Edge Add-ons Store, and available for manual download and installation.
Download the latest release and unzip it. Then navigate to chrome://extensions/ and enable "Developer mode" using the toggle in the top right corner. Upload the extension manually by pressing "Load unpacked" and selecting the unzipped TabCloser folder.
