User Reviews
Users repeatedly raise major privacy and security concerns (broad all‑site permissions and antivirus/Defender alerts). Reviews also show mixed functionality: some say it blocks Gmail tracking pixels as intended, while others report it doesn’t work reliably or is Firefox‑limited. A common complaint is that it focuses on Gmail and may not support other email services. Pros
- Intended purpose is to block/flag email tracking pixels (privacy protection) — mentioned as the add‑on’s goal in multiple reviews
- Some users report it successfully blocks/flags trackers in Gmail accounts
- Offered as a Firefox add‑on (widely discussed by reviewers)
Cons
- Requests very broad permissions (access to all websites), raising privacy and 'spying' concerns
- Flagged by antivirus/Windows Defender as malware or spyware by multiple users
- Inconsistent functionality — reports of it not working, being missing after install, or performing worse on Firefox than on Chrome
- Limited focus on Gmail only, so not useful for other email providers

Is Ugly Email 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.
Ugly Email requires some sensitive permissions that could impact your browser and data security. 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.
Ugly Email is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
