Worth knowing
Firefox
- The built-in VPN is capped at 50 GB per month and protects browser traffic only. Mozilla's paid VPN service costs $59.88 per year or $9.99 per month, plus tax.
- Firefox shows optional ads on its homepage to fund development. They can be turned off.
- The built-in VPN has not reached Firefox for Android or iOS; Mozilla's roadmap lists VPN on mobile as upcoming work.
- Windows 8.1 and below and macOS 10.14 and below are no longer supported by the standard release; they need Firefox ESR.
Orion
- The Linux version is in beta, and the Windows version is an alpha that has not been released.
- Custom app icons, the browser border and early access to beta builds are reserved for Orion+ members.
- Orion+ billing runs through a Kagi account, although a Kagi Search subscription is not required.
- On-page and offline translation with Kagi Translate requires macOS 26 or later.
Key features
Firefox
- Tracking and cookie protection
- Enhanced Tracking Protection blocks known trackers by default, and Total Cookie Protection keeps each site's cookies separate. The shield icon in the address bar shows what was blocked.
- Built-in VPN
- A VPN toggle in the desktop toolbar routes browser traffic through a proxy server to hide the IP address, free for up to 50 GB per month. It covers the browser only, not other apps on the device.
- Tab groups, vertical tabs and sidebar
- Tabs can be grouped and color coded or stacked vertically, and a customizable sidebar gives one-click access to bookmarks, history, synced tabs and other tools.
- AI chatbots in the sidebar
- The sidebar can host a third-party assistant such as ChatGPT, Gemini, Copilot, Claude or Mistral Chat. AI features are optional and can be turned off entirely.
- Sync with a Mozilla account
- Bookmarks, history, saved passwords and open tabs sync across desktop and mobile with end-to-end encryption, and Send Tab pushes a page from one device to another.
- Reader mode, PDF editor and translation
- Reader mode strips clutter from articles, a built-in editor fills, signs and annotates PDFs, and pages are translated in the browser without sharing the data with anyone else.
Orion
- Safari, Chrome and Firefox extensions
- Orion runs extensions from all three ecosystems, on iPhone and iPad as well as Mac, and keeps a curated gallery of extensions verified to work.
- Ad blocking and zero telemetry
- Ads and trackers are blocked natively by default, and Kagi states that the browser sends, tracks and collects nothing about its users.
- Profiles and containers
- Each profile gets its own browser, icon and Dock emoji to separate work from personal use, and containers keep accounts apart without switching browsers.
- Tree-style tabs and tab previews
- Tabs can sit in a parent-child hierarchy that collapses or closes as a group, be pinned or split into focused windows, and show a visual preview when switching.
- Focus Mode and per-site settings
- Focus Mode hides the whole interface so a site behaves like a web app, and per-site controls toggle the ad blocker, JavaScript, web fonts and permissions.
- Sync and Kagi services
- Bookmarks and passwords sync between Orion on Mac, iPhone and iPad without third-party tools, and Kagi Translate translates pages in place.
