  119. All distribution of Covered Software in Source Code Form, including any
  120. Modifications that You create or to which You contribute, must be under
  121. the terms of this License. You must inform recipients that the Source
  122. Code Form of the Covered Software is governed by the terms of this
  123. License, and how they can obtain a copy of this License. You may not
  124. attempt to alter or restrict the recipients' rights in the Source Code
  125. Form.
  126. #### 3.2. Distribution of Executable Form
  127. If You distribute Covered Software in Executable Form then:
  128. * **(a)** such Covered Software must also be made available in Source Code
  129. Form, as described in Section 3.1, and You must inform recipients of
  130. the Executable Form how they can obtain a copy of such Source Code
  131. Form by reasonable means in a timely manner, at a charge no more
  132. than the cost of distribution to the recipient; and
  133. * **(b)** You may distribute such Executable Form under the terms of this
  134. License, or sublicense it under different terms, provided that the
  135. license for the Executable Form does not attempt to limit or alter
  136. the recipients' rights in the Source Code Form under this License.
  137. #### 3.3. Distribution of a Larger Work
  138. You may create and distribute a Larger Work under terms of Your choice,
  139. provided that You also comply with the requirements of this License for
  140. the Covered Software. If the Larger Work is a combination of Covered
  141. Software with a work governed by one or more Secondary Licenses, and the
  142. Covered Software is not Incompatible With Secondary Licenses, this
  143. License permits You to additionally distribute such Covered Software
  144. under the terms of such Secondary License(s), so that the recipient of
  145. the Larger Work may, at their option, further distribute the Covered
  146. Software under the terms of either this License or such Secondary
  147. License(s).
  148. #### 3.4. Notices
  149. You may not remove or alter the substance of any license notices
  150. (including copyright notices, patent notices, disclaimers of warranty,
  151. or limitations of liability) contained within the Source Code Form of
  152. the Covered Software, except that You may alter any license notices to
  153. the extent required to remedy known factual inaccuracies.
  154. #### 3.5. Application of Additional Terms
  155. You may choose to offer, and to charge a fee for, warranty, support,
  156. indemnity or liability obligations to one or more recipients of Covered
  157. Software. However, You may do so only on Your own behalf, and not on
  158. behalf of any Contributor. You must make it absolutely clear that any
  159. such warranty, support, indemnity, or liability obligation is offered by
  160. You alone, and You hereby agree to indemnify every Contributor for any
  161. liability incurred by such Contributor as a result of warranty, support,
  162. indemnity or liability terms You offer. You may include additional
  163. disclaimers of warranty and limitations of liability specific to any
  164. jurisdiction.
  165. ### 4. Inability to Comply Due to Statute or Regulation
  166. If it is impossible for You to comply with any of the terms of this
  167. License with respect to some or all of the Covered Software due to
  168. statute, judicial order, or regulation then You must: **(a)** comply with
  169. the terms of this License to the maximum extent possible; and **(b)**
  170. describe the limitations and the code they affect. Such description must
  171. be placed in a text file included with all distributions of the Covered
  172. Software under this License. Except to the extent prohibited by statute
  173. or regulation, such description must be sufficiently detailed for a
  174. recipient of ordinary skill to be able to understand it.
  175. ### 5. Termination
  176. **5.1.** The rights granted under this License will terminate automatically
  177. if You fail to comply with any of its terms. However, if You become
  178. compliant, then the rights granted under this License from a particular
  179. Contributor are reinstated **(a)** provisionally, unless and until such
  180. Contributor explicitly and finally terminates Your grants, and **(b)** on an
  181. ongoing basis, if such Contributor fails to notify You of the
  182. non-compliance by some reasonable means prior to 60 days after You have
  183. come back into compliance. Moreover, Your grants from a particular
  184. Contributor are reinstated on an ongoing basis if such Contributor
  185. notifies You of the non-compliance by some reasonable means, this is the
  186. first time You have received notice of non-compliance with this License
  187. from such Contributor, and You become compliant prior to 30 days after
  188. Your receipt of the notice.
  189. **5.2.** If You initiate litigation against any entity by asserting a patent
  190. infringement claim (excluding declaratory judgment actions,
  191. counter-claims, and cross-claims) alleging that a Contributor Version
  192. directly or indirectly infringes any patent, then the rights granted to
  193. You by any and all Contributors for the Covered Software under Section
  194. 2.1 of this License shall terminate.
  195. **5.3.** In the event of termination under Sections 5.1 or 5.2 above, all
  196. end user license agreements (excluding distributors and resellers) which
  197. have been validly granted by You or Your distributors under this License
  198. prior to termination shall survive termination.
  199. ### 6. Disclaimer of Warranty
  200. > Covered Software is provided under this License on an “as is”
  201. > basis, without warranty of any kind, either expressed, implied, or
  202. > statutory, including, without limitation, warranties that the
  203. > Covered Software is free of defects, merchantable, fit for a
  204. > particular purpose or non-infringing. The entire risk as to the
  205. > quality and performance of the Covered Software is with You.
  206. > Should any Covered Software prove defective in any respect, You
  207. > (not any Contributor) assume the cost of any necessary servicing,
  208. > repair, or correction. This disclaimer of warranty constitutes an
  209. > essential part of this License. No use of any Covered Software is
  210. > authorized under this License except under this disclaimer.
  211. ### 7. Limitation of Liability
  212. > Under no circumstances and under no legal theory, whether tort
  213. > (including negligence), contract, or otherwise, shall any
  214. > Contributor, or anyone who distributes Covered Software as
  215. > permitted above, be liable to You for any direct, indirect,
  216. > special, incidental, or consequential damages of any character
  217. > including, without limitation, damages for lost profits, loss of
  218. > goodwill, work stoppage, computer failure or malfunction, or any
  219. > and all other commercial damages or losses, even if such party
  220. > shall have been informed of the possibility of such damages. This
  221. > limitation of liability shall not apply to liability for death or
  222. > personal injury resulting from such party's negligence to the
  223. > extent applicable law prohibits such limitation. Some
  224. > jurisdictions do not allow the exclusion or limitation of
  225. > incidental or consequential damages, so this exclusion and
  226. > limitation may not apply to You.
  227. ### 8. Litigation
  228. Any litigation relating to this License may be brought only in the
  229. courts of a jurisdiction where the defendant maintains its principal
  230. place of business and such litigation shall be governed by laws of that
  231. jurisdiction, without reference to its conflict-of-law provisions.
  232. Nothing in this Section shall prevent a party's ability to bring
  233. cross-claims or counter-claims.
  234. ### 9. Miscellaneous
  235. This License represents the complete agreement concerning the subject
  236. matter hereof. If any provision of this License is held to be
  237. unenforceable, such provision shall be reformed only to the extent
  238. necessary to make it enforceable. Any law or regulation which provides
  239. that the language of a contract shall be construed against the drafter
  240. shall not be used to construe this License against a Contributor.
  241. ### 10. Versions of the License
  242. #### 10.1. New Versions
  243. Mozilla Foundation is the license steward. Except as provided in Section
  244. 10.3, no one other than the license steward has the right to modify or

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