STR: 0. set keyword.enabled pref to false 1. open a new tab and try to load "::2600" 2. check the error console ER: no errors AR: something something failedChannel is null Pointing to: https://dxr.mozilla.org/mozilla-central/rev/c5da92c5b4906369dee83629f81d647226ac1038/browser/base/content/content.js#459 because when error reporting is automatic, apparently we always run this. I'm not sure if this means we're always submitting or something, but it warrants investigating, and we should at least bail out at the start of that method if there is no failedChannel. But we should probably also ensure we're not trying to phone home about e.g. non-existent domains or any of the other myriad things we use about:neterror for... Panos, can you investigate this?
On Nightly I see the following before that error: [Exception... "Component returned failure code: 0x804b000a (NS_ERROR_MALFORMED_URI) [nsIURIFixup.createFixupURI]" nsresult: "0x804b000a (NS_ERROR_MALFORMED_URI)" location: "JS frame :: resource:///modules/PlacesUIUtils.jsm :: PUIU_createFixedURI :: line 95" data: no] urlbarBindings.xml:390:0 On fx-team I see only the above. I'm updating to check on fx-team tip.
I can no longer see the message from comment 0 in either fx-team tip or the latest nightly. Could it be something that was already fixed?
(In reply to Panos Astithas [:past] from comment #2) > I can no longer see the message from comment 0 in either fx-team tip or the > latest nightly. Could it be something that was already fixed? I still see: 11:39:11.930 TypeError: docShell.failedChannel.securityInfo is null content.js:459:9 on latest nightly (Jan. 24, today's isn't out yet). Maybe this only reproduces with e10s off? Either way, it still seems to me that we should change some of the assumptions here. Reading https://dxr.mozilla.org/mozilla-central/source/browser/base/content/content.js#385-396, it looks like SSL-related code now always run son about:neterror, even when the error isn't SSL-related at all.
I can't reproduce this anymore, likely because a bunch of this moved to the backend.
