Features

Quality of life, built in.

Everything Peppermint adds on top of a solid Firefox base. Focused, fast and refreshingly unbloated.

Built-in blocker

Ad blocking that just works

No extension to install or maintain. Pick Light, Medium or Heavy, and Peppermint blocks ads, trackers and video ads (including YouTube) while the filter engine compiles off the main thread so pages stay fast.

  • Light, Medium and Heavy protection levels
  • Standard and video ad blocking
  • Per-site overrides from the site panel
  • Custom filter rules on top of your level

Markdown notepad

MintNotes, always one tab away

Open mint://note and jot things down in a full markdown editor, without leaving the browser. Type a slash for headings, lists, tasks and code blocks, rename notes in place, export when you are done, and keep the ones that matter with encrypted saving.

  • Full markdown with slash commands
  • Integrated encrypted saving
  • In-place renaming and quick export
  • Reachable from the address bar and command palette

Temporary permissions

Permissions with an expiry date

Most permission prompts are one-off decisions. Allow a site once, for a limited time or for the current tab only, and Peppermint takes the access back on its own.

  • Allow once
  • Allow for a set time
  • Allow for this tab
  • Or always, if you really mean it

Address-bar shortcuts

URL snippets for your fingertips

Define your own shortcuts and open anything in a keystroke. Type >yt and you are on YouTube. Snippets live in the address bar, so there is nothing new to learn.

  • Type > then your shortcut
  • Unlimited custom snippets
  • Managed from Settings
  • Works alongside search

Battery and memory saver

Underpowered mode for long days

Running on a low battery or an older machine? Underpowered Mode freezes background tabs and limits resource use. Idle tabs also unload on their own after a time you choose, with pinned, playing and active tabs left alone.

  • One-click toggle in the toolbar
  • Freezes background tabs
  • Automatic idle-tab unloading
  • Notifies you with a frosted toast

Peppermint Janitor

A janitor that cleans up quietly

Every time Peppermint starts, the Janitor clears files that nothing has used for 72 hours. Your documents, downloads and browser data are never touched. It is off until you say yes.

  • Opt-in, never automatic
  • Temp files, caches, traces and update leftovers
  • Optional recycle bin cleanup
  • Tidy summary toasts

Rich new tab

A homepage worth opening

Your new tab greets you with time spent browsing, your most used site, network speed, downloads and more. Choose the cards you like, or switch to a blank page or your own URL.

  • Optional stat cards and clock
  • Built-in, blank or custom homepage
  • No sponsored shortcuts
  • Frosted glass cards

Private windows

Ghost mode, more secure

Open a Ghost Window straight from the toolbar for sessions that leave nothing behind. Peppermint’s Ghost mode is hardened beyond a standard private window.

  • One-click Ghost Window
  • Hardened defaults
  • No telemetry, studies or Pocket
  • Leaves nothing behind

Reader mode

Reading, minus the noise

Turn any article into a clean, focused page and save it for later. Great for long reads, research and anything that deserves your full attention.

  • Clean, typographic reading view
  • Saved articles page
  • Images preserved
  • Distraction-free layout

Design

A polished frosted-glass interface

Peppermint refines the Zen interface with more organised settings, consistent panel colours and a frosted-glass look that adapts to the page behind it. Light, dark and auto themes included.

  • Consistent panels and settings
  • Adaptive frosted URL bar
  • Light, dark and auto themes
  • Compositor-friendly animations

Inherited from Zen

Vertical tabs, spaces and split view

Peppermint keeps everything people love about Zen: a native vertical tab bar that breathes, spaces to separate contexts, split view, Glance and a command palette for keyboard-first navigation.

  • Native vertical tab bar
  • Spaces and folders
  • Split view and Glance
  • Command palette (Ctrl/Cmd + K)
