In-depth safety analysis

This extension requests the storage permission, which allows it to save your preferred window sizes and settings locally. It also uses system.display, which lets it read information about your connected screens (such as their dimensions) and resize browser windows accordingly. This set of permissions is narrowly focused and entirely expected for a tool whose core function is managing window sizes.

For a general browser utility like this, typical safety considerations are relatively mild. The main thing a careful user should know is that extensions in this category can sometimes be cloned or imitated by malicious actors. It is wise to verify you are installing the official version from a reputable publisher, especially since resizing tools do not need to access the content of the web pages you visit.

Looking at the fact sheet, the strongest dimension is Maintenance & Ownership, which suggests the extension is actively kept up to date. The weakest dimension is Publisher & Identity, indicating that less verifiable information is available about the developer behind the tool. This is not uncommon for simple utilities, but it means users must place a degree of trust in the publisher without strong external validation.

AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.

Who's Behind Window Resizer?

  • Publisher Lynn

Public records identify the publisher, but no individual founders or a separate registered company are named — which is what holds the Publisher & Identity score back. Less public information about who operates an extension means less you can verify about their long-term accountability.
