Mail Hash Firefox

Mail Hash

By: jsvde
Add a random hash to a plus addressable email address or to a custom domain

Features & Capabilities

Email providers that support plus addressing or tagging enable you to append something to your address and still receive it in your normal inbox.

Mail Hash adds a random hash to your email, e.g your.name@gmail.com becomes your.name+ts5ag@gmail.com Use this for sign up's that require email and password. Each service you sign up for stores your under a different hash.

When some service gets hacked and the attackers obtain email and password combinations, they can't use it to brute force other services you might use, due to the different hash.

Additionally you can choose between plus addressing and custom domains. In the case of custom domains, you supply the domain and Mail Hash adds a random hash to use with catch-all email filter. e.g. your-domain.com becomes hiuaiu4szdiu6as6g1@your-domain.com

Please use it in combination with a password manager.

Is Mail Hash 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.

Mail Hash 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.

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