Why This Matters

The introduction of native Containers in Firefox 153 enhances user privacy and organization by allowing seamless separation of online activities within a single browser window. This feature reduces unwanted tracking and simplifies managing multiple accounts, benefiting both everyday users and privacy-conscious individuals. By integrating Containers directly into Firefox, Mozilla is streamlining digital workflows and reinforcing its commitment to user privacy and control.

Key Takeaways

Today, we’re excited to announce the Preview of Containers in Firefox version 153, which lets you keep separate parts of your online life (work, shopping, personal, banking) logged into different accounts in the same browser window, but keeps your cookies and ad tracking isolated inside each container.

This means that stuff you do in one container isn’t seen by other containers. No longer will you search for a new hat to wear to a party, only to be inundated with ads for hats at every twist and turn on the internet for weeks to come.

For almost a decade, many of you have relied on our Multi-Account Containers extension to keep work, personal, and privacy-sensitive browsing separate without needing multiple browsers or profiles.

We’ve heard your feedback and understood the value you find in that separation. Now, we’re bringing the power of the Multi-Account Containers extension directly into the heart of Firefox for all to benefit from.
