Extension Metadata

About this extension
SmartWindowSize automatically restores your preferred browser window size for websites.

Set a browser window to the size you want and save a rule for the current website. The next time you open that site, SmartWindowSize restores the saved dimensions automatically.

Rules can be created for an entire domain, an exact domain, a URL and its subpaths, or URLs with different levels of query-parameter matching. More specific rules take priority over broader ones.

SmartWindowSize can also:
  • Remember an optional window position and monitor for individual rules.
  • Automatically apply a default size to websites without a saved rule.
  • Remember manually adjusted window sizes.
  • Set exact window dimensions using presets or custom pixel values.
  • Bring off-screen windows back onto the visible desktop area.
  • Keep maximized and fullscreen windows untouched.
  • Export and import settings and rules as JSON.
  • Be temporarily disabled without losing your configuration.

All settings and rules are stored locally in your browser. SmartWindowSize does not send website addresses, window information, diagnostics, or personal data outside your browser.

It uses no analytics, telemetry, advertising, external servers, network requests, or native applications.
