Features & Capabilities

Mobile Dyslexic is a Chrome extension that enhances web readability for people with dyslexia by replacing all fonts on web pages with a carefully crafted, dyslexia-friendly font. This font features weighted bottoms and increased letter spacing, helping users better recognize individual letters and their orientation. The extension is based on the OpenDyslexic typeface and supports Firefox for Android, making it one of the first mobile platforms to consider dyslexic readers.

Once installed, Mobile Dyslexic activates automatically and can be toggled on or off via a convenient "D" button on desktop or the main menu on mobile. While it enforces a uniform dyslexia-friendly font across all content, it attempts to avoid replacing special glyph fonts to minimize display issues. Users are encouraged to provide feedback if they encounter any font replacement problems to improve compatibility.

User Reviews

Users broadly praise Mobile Dyslexic for improving readability and reducing eye strain across most sites. It's fast to load, easy to use, and supports OpenDyslexic well, aiding long-form reading and accessibility. However, there are recurring issues: icons often break or disappear on many sites, Google Docs/Drive pages show compatibility problems, and the default font size can be oversized on some pages. Users would like more font-size control and fewer display glitches.

Pros

Significantly improves readability and reduces eye strain across most sites.
Fast to load and generally reliable, with quick, one-click use.
Strong OpenDyslexic font support, praised as one of the best options for dyslexic users.
Helpful for long-form reading and overall accessibility.

Cons

Icons frequently break or disappear on various sites (often appearing as broken icons or boxes).
Poor compatibility with Google Docs/Drive pages (does not function or disrupts Google services).
Default font size can be too large on some sites, causing layout issues; users want a font-size control.

works on almost all websites, but increases font size. this causes issues on certain websites. does not function on google docs (google docs is the issue, but it is a commonly used) very useful, thank you so much, please fix the sizing

Great add-on/font extension! One minor inconvenience is, the icons on google maps are broken, which is slightly annoying. I can always hover over the icon to figure out what it is though so its not detrimental. No other website I have found has this problem though. If you could look into this, it would be cool. Thanks again!

Is Mobile 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.

Mobile Dyslexic requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****

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