User Reviews

User reviews praise the add-on for reliability, speed, and the added capability of emulating phone HTTP requests for backend work, making it useful for testing before buying a device. However, multiple users report stability issues and incomplete functionality, especially around orientation (no landscape/rotation, no scrolling). There are also concerns about the premium features not working on Firefox and poor developer support. A few comparisons to Chrome and concerns about pricing have been noted, but core positives center on usable performance and extended emulation features.

Pros

Works reliably and quickly.
Emulates device HTTP requests for backend processing beyond simple viewport resizing.
Useful for testing devices before purchasing.

Cons

Reported unstable functionality and bugs, with some reviews noting it doesn’t work as expected.
Cannot rotate or view in landscape orientation and cannot scroll, limiting device emulation features.
Premium/Pro features don’t work on Firefox and there is little or no developer support.

Recent reviews

Praticamente, non funziona. Non è un simulatore di device ma è soltanto un rimpicciolitore di schermo.

Is Mobile emulator 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.

Mobile emulator requires a lot of sensitive permissions. Exercise caution before installing.

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.

Mobile emulator has earned a fairly good reputation and likely can be trusted.
