Each Contributor hereby grants You a world-wide, royalty-free,
non-exclusive license:
(a) under intellectual property rights (other than patent or trademark)

become effective for each Contribution on the date the Contributor first
distributes such Contribution.
2.3. Limitations on Grant Scope
The licenses granted in this Section 2 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) above, no patent license is granted by a
(a) for any code that a Contributor has removed from Covered Software;
(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).
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) or under the terms of a Secondary License (if
permitted under the terms of Section 3.3).
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
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.

* 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, 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
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
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.
Exhibit A - Source Code Form License Notice
This Source Code Form is subject to the terms of the Mozilla Public
License, v. 2.0. If a copy of the MPL was not distributed with this
file, You can obtain one at
If it is not possible or desirable to put the notice in a particular
file, then You may include the notice in a location (such as a LICENSE
file in a relevant directory) where a recipient would be likely to look
for such a notice.
You may add additional accurate notices of copyright ownership.
Exhibit B - "Incompatible With Secondary Licenses" Notice
This Source Code Form is "Incompatible With Secondary Licenses", as
defined by the Mozilla Public License, v. 2.0.
A [Firefox add-on]( that emulates Content Delivery Networks locally by intercepting requests, finding the required resource and injecting it into the environment. This all happens instantaneously, automatically, and no prior configuration is required.
> **Note:** Decentraleyes is no silver bullet, but it does prevent a lot of websites from making you send these kinds of requests. Ultimately, you can make Decentraleyes block requests for any missing CDN resources, too.
## Roadmap
Now that there's a solid, Mozilla approved, foundation, it's time to move forward. Mobility, extensibility (through support for community-powered resource packages), and usability, will be the main points of attention during this phase.
#### Planned Features
* Advanced policy management for users who block requests for missing resources.
* Smarter resource version interpretation for handling dynamic notations.
* A minimalistic and non-essential graphical user interface.
* Support for custom, importable, library repositories.
> **Note:** These long-term goals are subjective to change, and can be discussed. That is, as long as the suggestions do not conflict with the ultimate goal of realizing a free and open standard for exchanging web resource bundles.
## Contributing
Suggestions in the form of **Issues** and contributions in the form of **Pull Requests** are highly welcome. You can also use the contact details and PGP key on the add-on [download page]( to get in touch.
#### Prerequisites
* Jetpack Manager [jpm]( (a Node-based replacement for cfx).
* Firefox version 38 or later. *If you need to work with earlier versions of Firefox, you'll need to use the old cfx tool. See instructions for [getting started with cfx](
#### Build Instructions (Unix)
git clone
cd decentraleyes
jpm xpi
## License
[MPL 2.0](
This script (first introduced in Decentraleyes v1.1.5) should make reviewing this extension a lot easier than it used to be. It's open source and open for scrutiny, and it automatically compares the bundled libraries (resources) to their original sources (after removing any source mapping URLs).
This usage guide is tailored to Linux based operating systems. If you're on a different type of system, the easiest direct solution might be to launch a free Linux box with Node.js pre-installed on Red Hat OpenShift. You can then SSH into it (after adding your own machine's public key to your account).
Having said that, every terminal command in the usage guide below comes with a description, so it should not be too hard to get this done on practically any type of configuration.
1. Make sure you have Node.js installed on your machine (or install it).
2. Open up a terminal and 'cd' into this directory.
Description: Navigate to this directory.
3. Execute 'rm -r ./node_modules; npm install' to ensure dependency integrity.
Description: Remove the node modules folder and reinstall dependencies using npm.
Note: If this fails, compare dependency file hashes and leave the folder in place.
4. Run the audit script by executing 'node run'.
Description: Run the script through Node.js and view the output.
Note: If you'd like to store the report, run 'node run > report.txt'.
Note description: It's possible to write the console output to a file.

\ No newline at end of file
### Version 0.4.0 (2015-11-12) ###
- Changed: sourceMappingURL comments used to be matched only when placed at
the end of the script. However, since several commonly used JavaScript
libraries do not follow this convention and all popular web browsers accept
non-trailing comments, this has been revised.
So now non-trailing SourceMappingURL comments are matched as well.
### Version 0.3.0 (2014-08-16) ###
- Changed: sourceMappingURL comments used to be matched only if they appeared
on their own line. However, the spec only says:
> The generated code may include a line at the end of the source, with the following form:
> //# sourceMappingURL=<url>
So now they are matched also when they appear on the same line as code.
- Removed: The `.set()` method. I couldn’t decide how it should work
considering the above change. Moreover, it was unnecessarily complex (and
would have gotten worse) for very little gain. It is much easier to run
`.remove()` if needed, and then simply `code += "\n//# sourceMappingURL=" +
url` (using the appropriate comment syntax and newline). KISS.
- Changed: The `.insertBefore()` method now always inserts the string exactly
before the sourceMappingURL comment; not before the newline before the
comment (if any). Moreover, it does not ensure that the comment will be on a
new line anymore. This is up to the caller. KISS.
- Changed: The `.remove()` method no longer removes the newline before the
sourceMappingURL (if any).
- Changed: Renamed `.get()` to `.getFrom()`.
- Changed: Renamed `.remove()` to `.removeFrom()`.
- Added: The `.existsIn()` method.
### Version 0.2.0 (2014-02-23) ###
- Changed: A space is no longer inserted before the closing comment syntax. If
such a space is desired, it needs to be put in the closing comment syntax
itself (such as `["/*", " */"]` instead of `["/*", "*/"]`). (Backwards
incompatible change.)
### Version 0.1.0 (2014-02-22) ###
- Initial release.
