Firefox addon stops working when packed in to xpi

Question

I've made an extension using the addon sdk, and it works as expected when running with cfx run. But when I pack it in to an xpi using cfx xpi and install it - it stops working - no scripts are injected and I'm not even getting any errors :(

Any ideas on how to fix this, or how can I debug this kind of issue?

Answer 1

Found a solution. I'm simply using the .xpi that Firefox packs automatically for testing. In order to use it, run the cfx run with the -p parameter pointing to a profile you've created, like this:

cfx run -p <your path to firefox>\profiles\someprofile

After running, go the that profile's folder, and find in there the extensions folder, it should be something like this:

<your path to firefox>\profiles\someprofile\extensions

In there you'll have your addon with a weird file name and an .xpi file extension. Rename it to anything you want, leaving the .xpi file extension intact.

EDIT: Apparently the cfx xpi command strips by default what it thinks to be unused modules and .js files. To avoid this you need to run it with a special flag, like this: cfx xpi --no-strip-xpi
