FiddlerHook could not be verified for use in Nightly and has been disabled

[Vmb]

Firefox Nightly 42.0a1. See screenshot in the attachment.

 The "More Information" link URL is https://support.mozilla.org/en-US/kb/add-on-signing-in-firefox

The workaround untill signing is xpinstall.signatures.required in the about:config.

Hello,

Yup, Firefox changed their add-on API/requirements (again). FiddlerHook isn't necessary to use Fiddler with Firefox and you can simply leave it disabled.

This will work for now. In fact that key is already set to "false" in most recent 40.0(.2) release so it will install, but with a warning. But this is going to change. As Mozilla outlined:

"There won’t be any preferences or command line options to disable this." on this blog post:

https://blog.mozilla.org/addons/2015/02/10/extension-signing-safer-experience/

Granted FiddlerHook isn't required but it sure is helpful, and after using it for so long, programmed into my workflow as it currently works. It would be nice if you guys got it signed.

Just FYI, I'm using latest FiddlerHook 2.5.1.8.

Just FYI 2: The only other option is to move to the Developer Edition (or nightly) as this isn't going to affect them (for obvious reasons).

Regardless, thanks for a great set of tools!

FiddlerHook was submitted to Mozilla for signing.

Mozilla has declined to do so, and declined to respond to our email.

Hi,

You can try updating FiddlerHook and/or Firefox, Kevin. That looks like some unaccounted for change in the API of the Firefox version you have installed. Have in mind, though, that if you update Firefox to latest you'll encounter the signing problem.

We'll have another try with the signing but rather unfortunately that problem is still unsolved.

To reiterate, you don't need FiddlerHook to use Fiddler with Firefox. It was removed from Fiddler 4.6.2 for this reason.

http://www.telerik.com/blogs/configuring-firefox-for-fiddler explains how to use Fiddler with Firefox; no add-on is required.
