1514199 - browser.webRequest.onBeforeSendHeaders.addListener doesn't work for anything except addons.thunderbird.net/static/img/favicon.ico

Status: RESOLVED WORKSFORME

(Thunderbird :: Add-Ons: Extensions API, defect)

Description

[Reşat SABIQ (Reshat)]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:63.0) Gecko/20100101 Firefox/63.0

Steps to reproduce:

Looked into Thunderbird support for Blend In extension:
https://addons.mozilla.org/fr/firefox/addon/blend-in/?src=search



Actual results:

Only the following request[1] produces a call to the listener registered as follows[2]: 
[1] https://addons.thunderbird.net/static/img/favicon.ico?b=f3a832ee-5b998c90
[2] browser.webRequest.onBeforeSendHeaders.addListener(bu.httpOnModifyRequest,
									  {urls: ["<all_urls>"]},
									  ["blocking", "requestHeaders"]);


Expected results:

The listener should be notified of all web requests, as clearly requested above (which is what happens on Firefox).

P.S. As a result, i'm giving up on Thunderbird support in Blend In extension for now: until this issue is resolved.

For clarity: Thunderbird was supported even with an extra "Thunderfoxing" feature before WebExtensions. I just had time to look into it on a WebExtensions-capable Thunderbird installation, and for now i have to leave it unsupported in Blend In extension (for WebExtensions).

Works for me. Reporter's account is disabled, so I'm closing this.
