User Reviews

WindowSizer is praised for its simplicity, flexibility, and usefulness in customizing Firefox window sizes with saved presets and shortcut support, making it valuable for web developers and users needing precise window dimensions. Common issues include shortcut conflicts especially with Alt key codes, absence of window position controls, loss of presets on reinstall, and inability to adjust page zoom or font size. Despite these drawbacks, it remains a well-maintained, easy-to-use tool.

Is WindowSizer 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.

WindowSizer does not require any sensitive permissions.

Risk impact analysis details

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. 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.

WindowSizer is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
