アドオン SDKを起動したり実行したりする際に問題があっても、慌てる必要はありません！問題を突き止めるにはどこから着手すれば良いのかを順番に見ていきましょう。
Quarantine Problem on Mac OS X
On Mac OS X, you might see the following error when you try to run cfx:
/path/to/sdk/bin/cfx: /usr/bin/env: bad interpreter: Operation not permitted
This might be because the cfx executable file has been placed in quarantine during download from the Internet.
To get it out of quarantine, use the xattr -d command, specifying com.apple.quarantine as the name of the attribute to delete, and cfx as the file from which to delete that attribute:
xattr -d com.apple.quarantine /path/to/sdk/bin/cfx
Check Your Python
The SDK's cfx tool runs on Python. If you're having trouble getting cfx to run at all, make sure you have Python correctly installed.
Try running the following from a command line:
python --version
cfx currently expects Python 2.5 or 2.6. Older and newer versions may or may not work.
Check Your Firefox or XULRunner
cfx searches well known locations on your system for Firefox or XULRunner. cfx may not have found an installation, or if you have multiple installations, cfx may have found the wrong one. In those cases you need to use cfx's --binary option. See the cfx Tool guide for more information.
When you run cfx to test your add-on or run unit tests, it prints out the location of the Firefox or XULRunner binary that it found, so you can check its output to be sure.
Check Your Text Console
When errors are generated in the SDK's APIs and your code, they are logged to the text console. This should be the same console or shell from which you ran the cfx command.
Don't Leave Non-SDK Files Lying Around
Currently the SDK does not gracefully handle files and directories that it does not expect to encounter. If there are empty directories or directories or files that are not related to the SDK inside your addon-sdk directory or its sub-directories, try removing them.
Search for Known Issues
Someone else might have experienced your problem, too. Other users often post problems to the project mailing list. You can also browse the list of known issues or search for specific keywords.
Contact the Project Team and User Group
SDK users and project team members discuss problems and proposals on the project mailing list. Someone else may have had the same problem you do, so try searching the list. You're welcome to post a question, too.
You can also chat with other SDK users in #jetpack on Mozilla's IRC network.
And if you'd like to report a bug in the SDK, that's always welcome! You will need to create an account with Bugzilla, Mozilla's bug tracker.
Run the SDK's Unit Tests
The SDK comes with a suite of tests which ensures that its APIs work correctly. You can run it with the following command:
cfx testall
Some of the tests will open Firefox windows to check APIs related to the user interface, so don't be alarmed. Please let the suite finish before resuming your work.
When the suite is finished, your text console should contain output that looks something like this:

If you get lots of errors instead, that may be a sign that the SDK does not work properly on your system. In that case, please file a bug or send a message to the project mailing list. See the previous section for information on doing so.
