Firefox 153 is Now Released: Containers are Now Active by Default

With the Firefox 153 update, Mozilla is making the Container feature the default and adding new security restrictions for local network access. Mozilla is taking an important security-oriented step with version 153 of the Firefox browser. With this new update, the Container feature, which allows users to isolate their data, is now active by default.

Containers separate browser tabs, preventing data from leaking from one tab to another. While this structure helps protect sensitive information, it also makes it difficult for sites to collect data to create user profiles. Containers, previously available as an optional feature, now come bundled with the browser.

Users are presented with four pre-configured options: Personal, Business, Banking and Shopping. When opening a new tab, the desired container can be selected by right-clicking on the new tab button. Additionally, container selection can be required for each new tab from the Tabs and navigation section in the Settings menu.

Thanks to this feature, users can log in to different accounts for the same service within the same browser window. Containers take user privacy and security to the next level by isolating cookies. Users can also create their own custom containers if they need.

This flexibility offers a very useful structure for those who want to personalize their browser experience without compromising security. Firefox version 153 also brings new restrictions on local network access. This feature is designed to prevent websites from unauthorized access to devices or services on the local network.

Firefox now asks the user for permission when a website tries to connect to local network devices such as routers, printers, file servers, or smart TVs. In this way, it becomes difficult for malicious sites to scan vulnerable devices on the network or track the user. Users can manage which sites can access local network devices from the Permissions and data section in the Settings menu.

Permissions can be easily turned on and off on a site-by-site basis through this section. This feature, which is currently in the experimental phase, is gradually being offered to users. You can start using these new security tools immediately by downloading Firefox 153 from Mozilla's official website.
