The February 28, 2025 revision tied those rights to operating Firefox and doing what users request, and explicitly said Mozilla does not gain ownership of that content. Mozilla’s current terms, effective September 16, 2026, retain that limited-purpose framing; its support FAQ says the terms do not grant new rights to user data.
What changed in the Firefox Terms of Use?
Mozilla introduced Firefox Terms of Use alongside an updated Privacy Notice on February 26, 2025. It said it had historically relied on Firefox’s open-source license and public commitments, but wanted to explain rights, permissions, and data practices more clearly in a different technology landscape. Acknowledgment was planned for new users in early March and existing users later in the year. (Mozilla’s February 26 announcement)
The first version included a nonexclusive, royalty-free, worldwide license covering information users input or upload through Firefox, for helping them navigate and interact with online content. Critics considered the wording too broad and raised concerns about possible use of user data by advertisers or AI companies. Those concerns reflected how the language could be read; they do not establish that Mozilla used data for those purposes. (TechCrunch’s contemporaneous coverage)
On February 28, Mozilla’s Ajit Varma said the company had listened to community concerns about licensing and was revising the text to better reflect the limited scope of its interaction with data. The comparison below summarizes the difference in the published wording.

#1 Best Overall
| Issue | February 26 wording | February 28 revision |
|---|---|---|
| Scope of license | Covered information users input or upload through Firefox. | Rights necessary to operate Firefox, including a license to do as the user requests with content entered in Firefox. |
| Stated purpose | Helping users navigate and interact with online content. | Operating Firefox and fulfilling the user’s request. |
| Ownership | Did not make the same explicit no-ownership statement in the license wording. | Explicitly says the license gives Mozilla no ownership of the content. |
| Privacy Notice | Mozilla said the terms did not give it a right to use data beyond what the Privacy Notice described. | Specifically includes processing data as described in the Firefox Privacy Notice. |
The revised language said: “You give Mozilla the rights necessary to operate Firefox. This includes processing your data as we describe in the Firefox privacy notice. It also includes a nonexclusive, royalty-free, worldwide license for the purpose of doing as you request with the content you input in Firefox. This does not give Mozilla any ownership in that content.” (Mozilla’s February 28 update) Mozilla also removed an Acceptable Use Policy reference, saying it created more confusion than clarity.
Did Mozilla change what Firefox does with user data?
Mozilla said the revised terms clarified the scope of its permissions rather than changing how it used data. Its current terms say users grant rights necessary to operate Firefox, including processing data as described in the Firefox Privacy Notice. Mozilla’s support FAQ, last updated May 12, 2026, says the terms do not grant it new rights to user data and that the routine license language users found confusing was removed. These are Mozilla’s descriptions of its terms and practices, not an independent audit. (current Firefox Terms of Use; Mozilla’s Terms of Use FAQ)
Why did Mozilla stop saying it never sells your data?
Mozilla said it moved away from blanket wording such as “We never sell your data” because legal definitions of a sale can include sharing for “other valuable consideration,” not just a conventional payment. It disclosed sharing some data with partners in connection with optional New Tab ads and sponsored search suggestions. Mozilla says the shared data is stripped of potentially identifying information, shared in aggregate, or handled with privacy-preserving technologies. Those descriptions are Mozilla’s account; the reviewed sources do not independently verify them. (Mozilla’s February 28 explanation)
What do the current Firefox terms cover?
The live Terms of Use page says it is effective September 16, 2026. It describes Firefox as free and open-source software and sets out a binding agreement between Mozilla Corporation and the user. The terms grant a personal, nonexclusive license to install and use the executable browser. They apply to executable code; Firefox source code is provided under open-source licenses, including the Mozilla Public License. (Firefox Terms of Use)

Mozilla’s FAQ says Firefox is designed not to reveal users’ browsing history to Mozilla. It says that when history or bookmarks are synced, the data is sent to Mozilla’s servers after end-to-end encryption on the user’s device, so Mozilla says it cannot see which sites were visited. These are Mozilla’s statements about Firefox’s design and data handling, not an independent technical finding. The FAQ directs users to Firefox settings and the Privacy Notice for data controls and details. (Mozilla’s Terms of Use FAQ; Firefox Privacy Notice)
