Install from the Chrome Web Store

After the first listing is approved:

1. Open the Window Resize Manager Chrome Web Store listing.
2. Click Add to Chrome.
3. Pin Window Resize Manager from the Chrome extensions menu.
4. Open the toolbar popup from a normal Chrome browser window.
5. Choose a built-in preset or enter a custom size.

Install for Local Testing

1. Run npm run build.
2. Open chrome://extensions.
3. Enable Developer mode.
4. Click Load unpacked and select the generated dist/ directory.

For release testing, use dist/chromium/external after npm run check:release. Do not test public store behavior from the internal variant.

Troubleshooting

The Current Window Is Unavailable

Window Resize Manager works on normal Chrome browser windows. Chrome can block or limit resizing for minimized, fullscreen, extension, browser-internal, or restricted windows. Move to a normal browser window and try again.

Viewport Mode Cannot Measure the Page

Viewport mode uses a user-triggered one-shot numeric measurement of the active tab. Chrome can block script measurement on browser pages, extension pages, and some restricted schemes. When Chrome exposes safe numeric tab dimensions, the extension uses those as a fallback; otherwise it shows a local error and does not resize.

The Live Measurement Overlay Does Not Appear

On regular HTTP and HTTPS websites, resizing the Chrome window automatically shows a live measurement overlay at the bottom-right of the page; the toolbar popup does not need to be opened. The Open action opens the popup on Chrome 127 and newer; on an older version, use the toolbar icon. The overlay fades away two seconds after resizing stops and reappears during the next resize. When the extension is installed or updated, it also loads the overlay into matching regular-web pages that are already open. Chrome blocks content scripts on browser-internal pages such as chrome://extensions, extension pages, and other restricted schemes. The popup’s own current-window readout remains available when the page overlay is blocked.

Maximized Windows Change State

Chrome does not resize maximized windows directly. When applying a preset or custom size, Window Resize Manager restores the current window to normal state and then applies the requested dimensions.

Custom Presets Are Missing

Custom presets are stored locally in Chrome extension storage. They do not sync through a Window Resize Manager account or cloud service. Removing the extension or clearing extension storage can remove saved presets and recent custom sizes.
