Your AI agent, riding along in your real browser
A Firefox extension that lets your local AI agent — Claude Code or Codex — drive your real, logged-in Firefox over MCP. Access is granted per tab, not per site, across five permission levels — the agent only ever sees the exact tab you hand it, while your email, bank, and every other tab stay invisible. Off by default, approved per action, fully audited. Setup is one paste.

Off by default — every tab is invisible to the agent until you grant it, and Stop AI revokes instantly
Permission, not access
Everything the agent can do is granted by you, gated per tab, shown before it happens, and written to the log.
Drives your REAL Firefox — your actual session, cookies, and logins, not a separate browser
One-paste onboarding — paste a block into your agent and it clones, installs, and registers itself
Per tab, not per site — access is scoped to the exact tab you grant; every other tab stays invisible
Off by default — the agent sees nothing until you grant that tab a mode
Five-tier ladder: Off, Read, Browse, Assist, Developer — the agent can never raise its own level
Every click, fill, and script needs your approval — shown in trusted extension chrome, never the page
Instant Stop AI — revokes in-flight and future calls
Hash-chained, tamper-evident audit log of every decision
Bring your own agent — Claude Code or Codex — over a local MCP server
No re-login, no separate app — Ridealong lives inside the Firefox you already use
Permission modes
Five modes. You decide how far.
Set per tab, by you, in the popup. Each tier unlocks a little more — and the agent can never raise its own level.
02
Read
Read the page, find elements, wait for content, list open tabs.
03
Browse
Navigate to URLs — no prompt, but every navigation is logged.
04
Assist
Click and fill — each one shown in a trusted popup for your approval.
05
Developer
Run JavaScript in the page — full control, always approved, source shown.
Trust is the product
Letting an AI act in your real, logged-in browser only works if you stay in control. Ridealong treats that as the default, not a setting.
Per tab, not per site
Access is scoped to the exact tab you grant — never the whole website. The same site open in another tab, and every tab you haven’t granted, stays invisible to the agent.
Off by default
The agent can’t see or touch a tab until you grant it a mode — and granting one later never backfills what happened while it was blind.
Instant, real revoke
Stop AI immediately bumps a session epoch that’s re-checked before every action, so in-flight and future calls fail closed the moment you pull access.
Approval lives in trusted chrome, not the page
Click, fill, and run-script approvals open in a real extension window the hostile page can’t forge, click-jack, or auto-approve.
Bring your AI along — on your terms
Off by default, approved per action, killable instantly, and fully logged. Paste one block into Claude Code or Codex and it sets itself up.
