Installing Celerity: Chrome Web Store and Developer Mode

Install the Celerity new tab extension from the Chrome Web Store or load it manually in developer mode — takes under a minute either way.

Celerity is a Chrome extension that overrides the new tab page. You can install it in seconds from the Chrome Web Store, or load it directly from the source folder if you prefer to inspect or modify the code before running it. Both paths end in the same place: every new tab you open launches Celerity.

Requirements

• Google Chrome (any recent stable release). Celerity uses Manifest V3 and standard Chrome extension APIs — no additional software required.

Installation

Chrome Web Store

The Chrome Web Store path handles everything automatically: Chrome downloads, verifies, and activates the extension for you.

1. Open the Celerity listing

   Navigate to the Celerity page on the Chrome Web Store.

2. Click 'Add to Chrome'

   Click the Add to Chrome button on the listing page. A confirmation dialog lists the permissions the extension requests.

3. Confirm the installation

   Click Add extension in the dialog. Chrome downloads and activates Celerity immediately.

4. Open a new tab

   Press Ctrl + T (or ⌘ T on macOS). Celerity now appears instead of the default new tab page.

Manual (Developer Mode)

Load the unpacked extension directly from the source folder. Use this path if you cloned the repository or downloaded the source archive.

1. Open Chrome extensions

   In the Chrome address bar, navigate to chrome://extensions.

2. Enable Developer mode

   Toggle the Developer mode switch in the top-right corner of the extensions page. Extra controls appear in the toolbar.

3. Load the unpacked folder

   Click Load unpacked and select the celerity folder — the one that contains manifest.json at its root.

4. Open a new tab

   Press Ctrl + T (or ⌘ T on macOS). Celerity replaces the default new tab page immediately.

After installation

Once Celerity is active, every new tab you open displays the command launcher grid. No configuration is required to start using it — the 12 built-in shortcuts are ready immediately.

First-visit guidance

The first time you open a new tab after installation, the compass (help) icon in the top-right corner pulses with a border animation. Click it to read a quick overview of the commands and keyboard shortcuts. Once you close the help panel, the gear (settings) icon pulses in turn, inviting you to explore shortcut management.

Celerity requests only the storage permission, which it uses to save your shortcuts and theme preference to your browser’s local storage. The activeTab permission is listed as optional and is never requested during normal use.

Permissions reference

Permission	Type	Purpose
storage	Required	Persists shortcuts and theme settings across sessions
activeTab	Optional	Not used in normal operation

The extension overrides the new tab page via Chrome’s chrome_url_overrides.newtab mechanism, loading index.html in place of the default page. No remote code is executed; all scripts are bundled locally and governed by a strict Content Security Policy.
