Features & Capabilities

The OpenDyslexic Firefox extension is a tool designed to improve web page accessibility for people with dyslexia. Dyslexia is a learning disorder that affects a person's ability to read, write, and spell. It is estimated that up to 20% of the population may have dyslexia to some degree.

This Firefox extension applies the OpenDyslexic font to web pages, making it easier for people with dyslexia to read online content. The OpenDyslexic font is a typeface that has been specifically designed to be more readable for people with dyslexia. It has a unique style that makes it easier for people with dyslexia to distinguish between different letters and words.

The extension is easy to use. Once installed, simply click on the icon in your browser to toggle the OpenDyslexic font on or off. The extension will remember your preference, so you won't need to keep turning it on every time you visit a new website.

By applying the OpenDyslexic font to web pages, this Firefox extension can help people with dyslexia read online content with less frustration and greater ease. It can also help them stay engaged with online learning, social media, and other digital activities that may have previously been challenging.

I really love the idea of this but sometimes I want to untoggle. It would be really great if there was a quick way to toggle the extension on and off if needed

Is Open Dyslexic 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.

Open Dyslexic 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.

Open Dyslexic may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
