User reviews

Users praise the ShareX Firefox add-on for its excellent screenshot capabilities when used in conjunction with its desktop application. The desktop program is seen as superior to other screenshot software. However, many users found the add-on confusing initially because it requires enabling a specific integration option in the desktop app settings, which is not well documented in the add-on's description, leading to usability concerns.

Pros

Highly regarded screenshot software with excellent functionality through the desktop app.
Considered a superior replacement to other screenshot tools, including paid apps.
Reliable and stable performance as indicated by user praise.

Cons

The add-on alone does not function without the desktop application from getsharex.com.
Lack of clear explanation and guidance about enabling 'Enable Firefox Addon Support' in the desktop app settings.
User experience suffers due to insufficient documentation in the add-on's description.

Extension safety

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.

ShareX requires very minimum permissions.

Risk impact analysis details

Medium Facilitates communication between extensions and native applications, usually low risk if managed correctly.

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.

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