Mozilla is taking this step in Firefox to comply with the regulation California Consumer Privacy Act (CCPA), which entered into force on 1 January.
The CCPA, which is similar to the Europes General Data Protection Regulation (GDPR), gives people in California the right to know and control the personal data collected by the sites.
And while CCPA is addressing residents in California, the new Firefox change will be released to all users, worldwide.
In a post, Firefox said that it already collects very little information about its users. THE telemetry that it keeps depends on how many open tabs and how long the sessions are, but with the new information, you will be able to delete them as well.
Make sure you update your Firefox browser on January 7th. After you do this, refer to its settings or look for a guide on how to delete your data from it.
