Straight answers about reading mode in Chrome and Chromebook — and how Firefly Reading Mode (a free, privacy-first reader extension based on Mozilla Readability) fits in.
The quickest way: install a reader extension, then click its toolbar icon on any article. With Firefly Reading Mode (free on the Chrome Web Store), one click distills the page into a clean, paper-like reading view — no flags, no settings.
Chrome desktop does not ship a classic one-click reader view out of the box. You have three options:
chrome://flags. Experimental and subject to change.Yes — Chrome 114 and later include a Reading Mode side panel (Settings → Accessibility → Reading mode), but it is a sidebar, not a full-page reader view.
The built-in side panel re-renders the article text with basic font and color controls. The main page — with its ads, pop-ups, and sidebar recommendations — stays on screen. There is no outline navigation, no image grayscale or hide toggles, and no export.
Firefly Reading Mode takes over the entire page instead: automatic article extraction with Mozilla Readability, warm 2460K eye-care and dark OLED themes, outline navigation, width/font adjustments, and one-click Copy as Markdown. Everything is processed locally in your browser.
Install Firefly Reading Mode from the Chrome Web Store — it works on any Chromebook because ChromeOS runs the Chrome browser.
Open the Chrome Web Store on your Chromebook, click Add to Chrome, then click the firefly toolbar icon on any article. It is lightweight, requires no account, and is well suited to school and education devices: students get long-form articles without ads or distraction, and nothing they read leaves the device.

Yes — free to install from the Chrome Web Store, no account, no subscription, no upsells.
No. Data collection: none. Article extraction and rendering happen entirely in your browser using the open-source Mozilla Readability algorithm.
Chrome's Reading Mode is a basic sidebar. Firefly is a full-page, distraction-free reading environment built on Mozilla Readability — with themes, image controls, outline navigation, and Markdown export.
Yes. Click "Copy as Markdown" in reading mode and the cleaned article — headings, paragraphs, links, code blocks, and images — is converted and copied to your clipboard, ready for Obsidian, Notion, Logseq, or any Markdown editor.
Article-style pages: blogs, news, documentation, wikis, Medium, Wikipedia and similar long-form content.
Single-page apps or login-walled pages may need a moment to finish loading before entering reading mode. PDF files are not supported.
Click "Exit reading view" at the top right, press Esc, or click the Firefly toolbar icon again. The original page is restored exactly as it was.
