How and why Waterfox is here...

Waterfox was started back in March 2011 by Alex Kontos, a 16 year old student.
He had a fascination for the web and wanted to help expand on the ideals of what Mozilla had for a free and open web.
And so he decided to make Waterfox, a 64-Bit browser based on Mozilla's free and open source platform.

Waterfox was one of the first widely distributed 64-Bit browsers on the web and quickly gained a loyal following.
At a time Waterfox had one thing in mind: speed, but now Waterfox also attempts to be an ethical, user-oriented browser

Waterfox focuses on giving users choice while also helping make the world a better place.
Watefox is partners with Ecosia, a search engine that plants trees with its generated revenues.
The browser itself is focused on power users, which lets you make the important decisions.
There is no plugin whitelist, you can run whichever extensions you like and absolutely no data or
telemetry is sent back to Mozilla or the Waterfox project.

    2.4. Subsequent Licenses

    permitted under the terms of Section 3.3).
    2.5. Representation

    Contributions are its original creation(s) or it has sufficient rights
    to grant the rights to its Contributions conveyed by this License.
    2.6. Fair Use

    applicable copyright doctrines of fair use, fair dealing, or other
    2.7. Conditions
    Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
    in Section 2.1.
    3. Responsibilities
    3.1. Distribution of Source Form
    All distribution of Covered Software in Source Code Form, including any
    Modifications that You create or to which You contribute, must be under
    the terms of this License. You must inform recipients that the Source
    Code Form of the Covered Software is governed by the terms of this
    License, and how they can obtain a copy of this License. You may not
    attempt to alter or restrict the recipients' rights in the Source Code
    3.2. Distribution of Executable Form
    If You distribute Covered Software in Executable Form then:
    (a) such Covered Software must also be made available in Source Code
        Form, as described in Section 3.1, and You must inform recipients of
        the Executable Form how they can obtain a copy of such Source Code
        Form by reasonable means in a timely manner, at a charge no more
        than the cost of distribution to the recipient; and
    (b) You may distribute such Executable Form under the terms of this
        License, or sublicense it under different terms, provided that the
        license for the Executable Form does not attempt to limit or alter
        the recipients' rights in the Source Code Form under this License.
    3.3. Distribution of a Larger Work
    You may create and distribute a Larger Work under terms of Your choice,
    provided that You also comply with the requirements of this License for
    the Covered Software. If the Larger Work is a combination of Covered
    Software with a work governed by one or more Secondary Licenses, and the
    Covered Software is not Incompatible With Secondary Licenses, this
    License permits You to additionally distribute such Covered Software
    under the terms of such Secondary License(s), so that the recipient of
    the Larger Work may, at their option, further distribute the Covered
    Software under the terms of either this License or such Secondary
    3.4. Notices
    You may not remove or alter the substance of any license notices
    (including copyright notices, patent notices, disclaimers of warranty,
    or limitations of liability) contained within the Source Code Form of
    the Covered Software, except that You may alter any license notices to
    the extent required to remedy known factual inaccuracies.
    3.5. Application of Additional Terms
    You may choose to offer, and to charge a fee for, warranty, support,
    indemnity or liability obligations to one or more recipients of Covered
    Software. However, You may do so only on Your own behalf, and not on
    behalf of any Contributor. You must make it absolutely clear that any
    such warranty, support, indemnity, or liability obligation is offered by
    You alone, and You hereby agree to indemnify every Contributor for any
    liability incurred by such Contributor as a result of warranty, support,
    indemnity or liability terms You offer. You may include additional
    disclaimers of warranty and limitations of liability specific to any
    4. Inability to Comply Due to Statute or Regulation
    If it is impossible for You to comply with any of the terms of this
    License with respect to some or all of the Covered Software due to
    statute, judicial order, or regulation then You must: (a) comply with
    the terms of this License to the maximum extent possible; and (b)
    describe the limitations and the code they affect. Such description must
    be placed in a text file included with all distributions of the Covered
    Software under this License. Except to the extent prohibited by statute
    or regulation, such description must be sufficiently detailed for a
    recipient of ordinary skill to be able to understand it.
    5. Termination
    5.1. The rights granted under this License will terminate automatically
    if You fail to comply with any of its terms. However, if You become
    compliant, then the rights granted under this License from a particular
    Contributor are reinstated (a) provisionally, unless and until such
    Contributor explicitly and finally terminates Your grants, and (b) on an
    ongoing basis, if such Contributor fails to notify You of the
    non-compliance by some reasonable means prior to 60 days after You have
    come back into compliance. Moreover, Your grants from a particular
    Contributor are reinstated on an ongoing basis if such Contributor
    notifies You of the non-compliance by some reasonable means, this is the
    first time You have received notice of non-compliance with this License
    from such Contributor, and You become compliant prior to 30 days after
    Your receipt of the notice.
    5.2. If You initiate litigation against any entity by asserting a patent
    infringement claim (excluding declaratory judgment actions,
    counter-claims, and cross-claims) alleging that a Contributor Version
    directly or indirectly infringes any patent, then the rights granted to
    You by any and all Contributors for the Covered Software under Section
    2.1 of this License shall terminate.
    5.3. In the event of termination under Sections 5.1 or 5.2 above, all
    end user license agreements (excluding distributors and resellers) which
    have been validly granted by You or Your distributors under this License
    prior to termination shall survive termination.

    *  -------------------------                                           *

    *  Covered Software is provided under this License on an "as is"       *
    *  basis, without warranty of any kind, either expressed, implied, or  *
    *  statutory, including, without limitation, warranties that the       *
    *  Covered Software is free of defects, merchantable, fit for a        *
    *  particular purpose or non-infringing. The entire risk as to the     *
    *  quality and performance of the Covered Software is with You.        *
    *  Should any Covered Software prove defective in any respect, You     *
    *  (not any Contributor) assume the cost of any necessary servicing,   *
    *  repair, or correction. This disclaimer of warranty constitutes an   *
    *  essential part of this License. No use of any Covered Software is   *
    *  authorized under this License except under this disclaimer.         *
    *                                                                      *
    *                                                                      *

    *  --------------------------                                          *
    *                                                                      *
    *  Under no circumstances and under no legal theory, whether tort      *
    *  (including negligence), contract, or otherwise, shall any           *
    *  Contributor, or anyone who distributes Covered Software as          *
    *  permitted above, be liable to You for any direct, indirect,         *
    *  special, incidental, or consequential damages of any character      *
    *  including, without limitation, damages for lost profits, loss of    *
    *  goodwill, work stoppage, computer failure or malfunction, or any    *
    *  and all other commercial damages or losses, even if such party      *
    *  shall have been informed of the possibility of such damages. This   *
    *  limitation of liability shall not apply to liability for death or   *
    *  personal injury resulting from such party's negligence to the       *
    *  extent applicable law prohibits such limitation. Some               *
    *  jurisdictions do not allow the exclusion or limitation of           *
    *  incidental or consequential damages, so this exclusion and          *
    *  limitation may not apply to You.                                    *
    *                                                                      *
    8. Litigation
    Any litigation relating to this License may be brought only in the
    courts of a jurisdiction where the defendant maintains its principal
    place of business and such litigation shall be governed by laws of that
    jurisdiction, without reference to its conflict-of-law provisions.
    Nothing in this Section shall prevent a party's ability to bring
    cross-claims or counter-claims.
    9. Miscellaneous
    This License represents the complete agreement concerning the subject
    matter hereof. If any provision of this License is held to be
    unenforceable, such provision shall be reformed only to the extent
    necessary to make it enforceable. Any law or regulation which provides
    that the language of a contract shall be construed against the drafter
    shall not be used to construe this License against a Contributor.
    10. Versions of the License
    10.1. New Versions
    Mozilla Foundation is the license steward. Except as provided in Section
    10.3, no one other than the license steward has the right to modify or

    distinguishing version number.
    10.2. Effect of New Versions

    create a new license for such software, you may create and use a
    modified version of this License if you rename the license and remove
    any references to the name of the license steward (except to note that
    such modified license differs from this License).
