Mozilla Revises Firefox Terms of Use After User Feedback

Mozilla Revises Firefox Terms of Use Following User Concerns

Following feedback from its user base regarding recently updated Terms of Use, Mozilla, the creator of the Firefox browser, has revised its policy. The changes address concerns about potentially expansive language within the original document.

Addressing Concerns Over Data Usage

Initial criticism centered on the belief that the previous terms granted Mozilla overly broad rights regarding user-inputted data and uploaded content. Some users expressed worry that this data could be sold to advertising firms or companies developing artificial intelligence.

Mozilla clarified that this interpretation was inaccurate. The company stated the updated terms did not signify a shift in its data handling practices.

Furthermore, Mozilla emphasized that the original language updates were not motivated by a desire to commercialize user data. The company maintains that its data usage remains governed by the stipulations outlined in Firefox’s Privacy Notice.

Specific Language Sparked Controversy

Several critics highlighted specific phrasing within the new terms as particularly concerning. This language prompted questions about the extent of Mozilla’s data access and potential usage.

Mozilla’s product chief, Ajit Varma, announced the revisions, stating the goal was to “more clearly reflect the limited scope of how Mozilla interacts with user data.”

Clarification of Data Ownership

The updated policy explicitly states that Mozilla requests user data solely to facilitate the operation of the Firefox browser. This clarification underscores that the company does not claim ownership of the data provided by its users.

The revised terms now specifically state:

Removal of Confusing References

Mozilla also removed references to the Acceptable Use Policy from its terms, acknowledging that this inclusion was causing unnecessary confusion among users.

In addition to the terms themselves, the company updated its online Privacy FAQ to provide clearer explanations of the legal terminology used.

Evolving Legal Definitions of Data "Sales"

Mozilla explained that it removed certain blanket statements regarding the non-sale of user data due to the increasingly broad and evolving legal definition of a “data sale.”

The California Consumer Privacy Act (CCPA) was cited as an example. The CCPA defines “sale” as encompassing a wide range of data-sharing activities, including selling, renting, disclosing, or transferring personal information in exchange for any form of consideration.

Data Sharing Practices

Mozilla acknowledges that it does share some data with partners. This includes data used to power optional advertisements on the New Tab page and sponsored suggestions within the search bar. Details regarding these practices are available in the Privacy Notice.

However, the company asserts that any shared data is anonymized, stripped of personally identifying information, and shared only in aggregate form.

User Control Over Data Sharing

Mozilla confirmed that users retain the ability to manage and adjust their data-sharing preferences directly within the browser settings.
