**(a)** under intellectual property rights (other than patent or trademark) *Licensable* by such *Contributor* to use, reproduce, make available, modify, display, perform, distribute, and otherwise exploit its *Contributions*, either on an unmodified basis, with *Modifications*, or as part of a *Larger Work*; and

<span id="21b"></span>

**(b)** under *Patent Claims* of such *Contributor* to make, use, sell, offer for sale, have made, import, and otherwise transfer either its *Contributions* or its *Contributor Version*.

### 2.2. Effective Date

### 2.3. Limitations on Grant Scope
The licenses granted in this [Section 2](#2-license-grants-and-conditions) are the only rights granted under this *License*. No additional rights or licenses will be implied from the distribution or licensing of *Covered Software* under this *License*. Notwithstanding [Section 2.1(b)](#21b) above, no patent license is granted by a *Contributor*:

**(a)** for any code that a *Contributor* has removed from *Covered Software*; or

**(b)** for infringements caused by: **(i)** *Your* and any other third party's modifications of *Covered Software*, or **(ii)** the combination of its *Contributions* with other software (except as part of its *Contributor Version*); or

**(c)** under *Patent Claims* infringed by *Covered Software* in the absence of its *Contributions*.

This *License* does not grant any rights in the trademarks, service marks, or logos of any *Contributor* (except as may be necessary to comply with the notice requirements in [Section 3.4](#34-notices)).

### 2.4. Subsequent Licenses
No *Contributor* makes additional grants as a result of *Your* choice to distribute the *Covered Software* under a subsequent version of this *License* (see [Section 10.2](#102-effect-of-new-versions)) or under the terms of a *Secondary License* (if permitted under the terms of [Section 3.3](#33-distribution-of-a-larger-work)).

### 2.5. Representation
Each *Contributor* represents that the *Contributor* believes its *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
This *License* is not intended to limit any rights *You* have under applicable copyright doctrines of fair use, fair dealing, or other equivalents.

### 2.7. Conditions
[Sections 3.1](#31-distribution-of-source-form), [3.2](#32-distribution-of-executable-form), [3.3](#33-distribution-of-a-larger-work), and [3.4](#34-notices) are conditions of the licenses granted in [Section 2.1](#21-grants).

## 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 Form*.

### 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](#31-distribution-of-source-form), 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 License(s)*.

### 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 jurisdiction.

## 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

<span id="51"></span>

**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.

<span id="52"></span>

**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](#21-grants) of this *License* shall terminate.

**5.3.** In the event of termination under [Sections 5.1](#51) or [5.2](#52) 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.

## 6. Disclaimer of Warranty
***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.**

## 7. Limitation of Liability
**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](#103-modified-versions), no one other than the license steward has the right to modify or publish new versions of this *License*. Each version will be given a distinguishing version number.

### 10.2. Effect of New Versions
*You* may distribute the *Covered Software* under the terms of the version of the *License* under which *You* originally received the *Covered Software*, or under the terms of any subsequent version published by the license steward.

### 10.3. Modified Versions
If you create software not governed by this *License*, and you want to 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*).

### 10.4. Distributing *Source Code Form* that is *Incompatible With Secondary Licenses*
If *You* choose to distribute *Source Code Form* that is *Incompatible With Secondary Licenses* under the terms of this version of the *License*, the notice described in Exhibit B of this *License* must be attached.
