Bionic Reader Firefox

Bionic Reader

Bold the start of each word on any page for easier, faster reading.

Features & Capabilities

Bionic Reader helps you read web pages more comfortably by bolding the beginning of each word. Your eyes can pick up the start of a word quickly and glide through the rest—useful for long articles, news, documentation, blogs, and any site with a lot of text.

HOW IT WORKS When Bionic Reader is on, it walks through readable text on the page and applies “word fixation”: the first part of each word is shown in bold, and the remainder stays normal weight. You stay on the same website—nothing is sent to an external reader or app. Turn it off anytime and the page returns to normal.

KEY FEATURES • Works on the websites you visit • One-click toggle from the toolbar icon • On by default after install (you can turn it off instantly) • Two ways to control how much is bolded: – Percentage of letters in each word (default 50%) – Fixed number of leading letters (e.g. first 3 letters) • Live preview in Options so you can see the effect before you save • English and Spanish interface • Welcome page on first install with a quick overview

WHAT WE SKIP To keep pages usable, Bionic Reader does not change code blocks, scripts, form fields, text areas, or editable areas. It focuses on normal page content you actually read.

WHO IT’S FOR Anyone who wants a calmer, faster scanning experience on the web—especially on dense pages with lots of paragraphs. Some people find bold word starts helpful for focus and readability; others prefer it off on certain sites. You’re always in control with the toolbar switch.

PRIVACY & DATA Bionic Reader does not collect or transmit your personal data to us or to third-party servers. Your on/off state and fixation settings are stored locally in the browser only. Processing happens on your device in the page you are viewing.

PERMISSIONS • Storage: remembers whether Bionic Reader is on and your fixation settings (local only) • Access to sites: needed to apply the reading effect on the pages you open Bionic Reader does not replace your browser’s security or the privacy practices of the sites you visit.

TIPS • Reload a tab if a page loaded before you installed the extension • Open Options to tune percentage vs. fixed letters to your taste • Use the toolbar icon to disable the effect on sites where you want plain text

Is Bionic Reader 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.

Bionic Reader 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.

Bionic Reader is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
