Tab Cleanup

A small Chrome extension (Manifest V3) that closes stale tabs by URL pattern — built for the Okta sign-in pages, Zoom auto-open launchers, and other ephemeral tabs that pile up over a workday.

Install (unpacked)

1. Clone this repo.
2. Open chrome://extensions.
3. Enable Developer mode (top right).
4. Click Load unpacked and select this directory.
5. Pin the Tab Cleanup icon to the toolbar.

Use

• Click the toolbar icon to scan all tabs across all windows. The popup shows a per-pattern count and a single button to close everything matched.
• For 51+ matches, the close button requires a second click within 3 seconds — guards against accidental mass closes.
• Right-click the icon → Options (or click Edit patterns in the popup) to add, edit, disable, or delete patterns. Changes auto-save.

Patterns

Each pattern is one of:

• substring — true when tab.url.includes(pattern). Same semantics as the snippet this extension is built around.
• regex — true when new RegExp(pattern).test(tab.url). Invalid regexes are flagged in the options page and skipped at match time.

Defaults seeded on first run

Name	Type	Pattern
Okta authorize	substring	.okta.com/oauth2/v1/authorize
Zoom auto-open	substring	zoom.us/launch
Zoom join page	substring	zoom.us/j/
Zoom web client	substring	zoom.us/wc/join

Patterns are stored in chrome.storage.sync, so they sync across signed-in Chrome profiles.

Permissions

• tabs — to read tab URLs and close them.
• storage — to persist your pattern list.

No host permissions; no <all_urls>; no content scripts.

Updating

git pull

Then go to chrome://extensions and click the reload icon on the Tab Cleanup card.
