TabCloser 3

What is TabCloser?

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.

TabCloser Options

By default, Asana, Discord invites, Figma, 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.

Custom URLs

TabCloser 3 brings the ability to add custom URLs to the detection criteria. TabCloser will only close URLs that are an exact match to what is entered. That means if the URL is https://example.com/ instead of https://example.com, TabCloser will not close the tab because the trailing / is missing from the end of the entry. The Custom URL options is great for closing out out specific pages you may use, like leftover tabs from SSO, VPN, ..etc redirect pages.

URL Schema

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

Asana

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 ?.

AWS IAM Access Authorization

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.

Discord

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.

Figma

For Figma, TabCloser is using three patterns: ^https?://(?:www\.)?figma\.com/design/ for Figma Design files, ^https?://(?:www\.)?figma\.com/board/ for FigJam files, and ^https?://(?:www\.)?figma\.com/slides/ for Figma Slide files (note that TabCloser will not close /presentation/ files from shared Slide presentations).

TabCloser will not close tabs for Figma Community profiles, templates, plugins, ..etc. Only file URLs which can be redirected to the Figma desktop client.

Linear

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.

Microsoft Teams

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.

Notion

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.

Slack

(?!(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.

Spotify

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.

VS Code Live Share

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.

Webex

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.

Zoom

For Zoom, TabCloser is using ^https?://([a-z0-9-]+\\.)?zoom\\.us/[js]/[^/]+.*#success$

([a-z0-9-]+\\.)? matches to any subdomain that your Zoom may be using. zoom\\.us/ matches the core URL. [js]/ matches the /j/ and /s/ paths that the redirect URL may encounter. [^/]+ matches the meeting ID. .* matches anything between the meeting ID and #success, this accounts for things like a pwd being included in the URL. And of course, #success$ matches the "#success" at the end of URL that has been successfully redirected to the Zoom client.

Requested Permissions

TabCloser requests a few permissions in the manifest.json file.

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.

storage allows TabCloser to save your enabled or disabled auto close preferences for a particular service, saves custom URLs you enter, and saves the interval you've set for closing tabs from the options menu.

Privacy

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.
