Site support

MOB³ is a content browser, not a full browser engine. It is happiest with text-focused, server-rendered pages and gets rough on modern JavaScript apps.

Works well

• Documentation, blogs, news articles, wikis, forums, changelogs and old or server-rendered HTML.
• Headings, paragraphs, lists, links, tables, <pre> blocks, images and common presentational markup.
• Responsive pages that use @media width queries, basic flex rows, basic grid tracks, forms and simple JavaScript DOM effects.
• Reader mode (R or -reader) for long articles.

Often rough

• Single-page applications, module-only sites, heavy shadow DOM, custom elements and CSS-in-JS.
• Sites that require a browser check, CAPTCHA, unusual TLS or a specific certificate.
• Complex grid/flex layouts, sticky positioning, z-index stacking, floats, animations and generated content.
• Visual results from canvas, WebGL, video and WebAudio.
• Multipart/file-upload forms.

Not supported

• ES modules, workers, service workers, WebSocket, IndexedDB, WebRTC, geolocation, clipboard APIs, notifications and browser payment APIs.
• CSP enforcement, certificate UI and proxy configuration UI.
• Pixel screenshots for automation. MOB³ has no font rasterizer.

Tips

• -no-js shows the no-script fallback, which is sometimes more useful.
• R extracts the main article and removes navigation, sidebars and images.
• D asks sites for prefers-color-scheme: dark and keeps an author dark palette when the page already renders a dark background.
• -layout-budget low can keep a very large or generated page responsive.
• -dump -width 120 -no-color is handy for comparing layout without a terminal.
