Features & Capabilities

The web was not built for the way you read. Readabler fixes that — page by page, everywhere you go.

Some sites set body text at 13 pixels. Some run light grey on white. Some animate half the screen while you are trying to finish a sentence. You cannot rewrite those sites, and you should not have to. Readabler puts an accessibility panel in your toolbar and lets you adjust any page you land on: the typeface, the size, the spacing, the contrast, the colours, the motion, the noise. Turn something on once and it stays on — on that site, or on every site you open, whichever you prefer.

If you already know Readabler from the accessibility widget on other people's websites, this is the same engine, now working for you on sites that never installed it.

Press Alt+A, or click the icon in the toolbar, and the panel opens.

Is Readabler – Web Accessibility Toolbar 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.

Readabler – Web Accessibility Toolbar 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.

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.

Readabler – Web Accessibility Toolbar is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.

Risk likelihood analysis details
