Features & Capabilities

The Adjust Viewport Size Chrome extension enables users to resize their browser window to match the viewport size perfectly. This helps developers and designers test responsive layouts efficiently. Key features include a sortable preset list powered by Sortable.js, allowing quick switching between common viewport sizes. Users can utilize a convenient hotkey (Alt+Shift+n or Option+Shift+n) to resize instantly, with automatic detection of scrollbar thickness to ensure accuracy.

The extension displays current viewport information and supports exporting and importing presets as JSON files through the options page. Notably, it requires no special permissions, ensuring privacy and security for users. Adjust Viewport Size is ideal for web professionals seeking precise control over browser dimensions during development and testing.

Is Adjust Viewport Size Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Adjust Viewport Size does not require any sensitive permissions.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious.

Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
