Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[Paddy O'Reilly]

User-Agent:       Mozilla/5.0 (X11; Linux i686; rv:2.0b2) Gecko/20100720 Firefox/4.0b2
Build Identifier: Mozilla/5.0 (X11; Linux i686; rv:2.0b2) Gecko/20100720 Firefox/4.0b2

I am currently developing an extension to handle the market:// protocol.
Currently it works in the most recent Firefox stable on all platforms, however it does not work in FF 4 B2
The extension is based on the exsisting FF 3.* extension "MLDonkey Protocol Handler"

Reproducible: Always

Steps to Reproduce:
1. Install extension that handles a protocol in FF 3.*
2. Attempt to open a URI for the protocol being handled.
3.
Actual Results:  
Firefox returns a prompt "Firefox doesn't know how to open this address, because the protocol (market) isn't associated with any program."

Expected Results:  
The link is passed to the relevant protocol handler.

Are you sure that the external application exists, is executable and you set the correct path to it ?

Comment 2

[Paddy O'Reilly]

The extension does not pass the URI to an external application, rather it is processed by an internal function within the extension.

It does work correctly under FF 3.*

Old-school XUL add-ons are unfortunately no longer around, but we do have WebExtension APIs for registering protocol handlers: https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/protocol_handlers

I would be very surprised, Paddy, if you're still blocked on this somehow, but just in case, the above documentation may be helpful. We're going to close this one out as INCOMPLETE in the interim.
