CookieSession

👥 TWO ACCOUNTS, SIDE BY SIDE

Need two accounts on the same website?

Whether it's Gmail, Instagram, Facebook, Discord, or any other site, CookieSession lets you open another logged-in account in a separate tab with a single click.

No more private windows, multiple browsers, or constantly logging out and back in.

Unlike other browsers, Firefox lets both accounts stay open at the same time, side by side in different tabs.

🚀 GET STARTED IN SECONDS

1⃣ Visit any website. 2⃣ Click the CookieSession icon and choose Enable for this tab. 3⃣ The page reopens in its own isolated session—just sign in with your other account.

That's it. Your original tab stays logged in while the new tab gets its own completely separate cookies.

No setup. No configuration. Nothing to learn.

🎨 COLOR-CODED SESSIONS

Every isolated session gets its own color, making it easy to tell accounts apart.

The first session is green, then orange, blue, pink, purple, and more.

You'll see the color in:

🟢 The toolbar icon 🎛 The extension popup 🏷 Firefox's colored tab indicator

Open as many isolated sessions for the same website as you need and always know which account you're using.

🧹 CLEANS UP AUTOMATICALLY

Each isolated session runs inside its own temporary Firefox container.

When you close the tab—or click Disable—the container is automatically removed along with all of its cookies and website data.

Nothing is left behind, making CookieSession perfect for both personal and shared computers.

CookieSession is built on Firefox's native Container Tabs technology—the same foundation used by Firefox Multi-Account Containers—but without the manual management.

One click creates a temporary isolated container for the current tab, and it's automatically deleted when you're done.

No naming containers. No organizing them. No cleanup required. Just click, sign in, and switch accounts effortlessly.
