Status: RESOLVED DUPLICATE of bug 1244474

(WebExtensions :: Untriaged, defect)

Description

Hi

My extension based on WebExtensions started failing in the recent nightlies. It worked a week ago. Now it does not load at all. If I try to reinstall it, it also fails with message "This add-on could not be installed because it appears to be corrupt."

If I open the browser console. I see this:

1454587156812	addons.webextension.<unknown>	ERROR	Loading extension 'null': Reading manifest: Unexpected properties: content_security_policy,incognito

Link to my addon:
https://addons.mozilla.org/firefox/addon/salesforce-inspector/

Source code:
https://github.com/sorenkrabbe/Chrome-Salesforce-inspector

I cannot remove the two properties it complains about, because if I do my extension does not work correctly in Google Chrome.

Bug 1244474 seems to be related, this might be a duplicate of that, but I am not sure.

Yep, this is definitely caused by that bug.  Thank you for filing this one, since it helps us know what manifest properties people need us to implement!
