823018 - New tab does not open Chrome’s "New Tab" Page anymore, but throws error.

Status: RESOLVED WORKSFORME

(Firefox :: Untriaged, defect)

Description

[Magnus]

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:17.0) Gecko/20100101 Firefox/17.0
Build ID: 20121128204232

Steps to reproduce:

Whenever I open a new tab at this Compter (Win7 Starter) this bub appears. To exclude problems with Pug-Ins, I started with disabled Plug-Ins, but the Error does not disappear.


Actual results:

A white new Tab opens.
The Error console first throws the message:
No chrome package registered for chrome://unitedtb/content/newtab/newtab-page.xhtml
Then it throws the Error:
Error: [Exception... "Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIWebNavigation.loadURI]"  nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)"  location: "JS frame :: chrome://global/content/bindings/browser.xml :: loadURIWithFlags :: line 156"  data: no]
Source File: chrome://browser/content/tabbrowser.xml
Line: 1361


Expected results:

A new Tab should open with 9 small frames for the 9 most visited pages or pages which are "pinned" there. I pinned a few pages there some versions of Firefox ago.

To my knowledge this New-Tab page is now part of a normal Firefox installation and I can not remember fiddling arround with this functionality. The feature still works at my other computers with Windows 7 Professional. I can not tell why it does not work (anymore) and have no idea how to fix it.

Please try it with Firefox:help/restart with addons disabled 

What happens if you enter about:newtab in Firefox as URL ?

Hi Matti

As for the first point, I already did this (thats what I meant with "started with disabled Plug-Ins") and the result is the same as without disabled plugins.

When I enter "about:newtab" the usual window with the 9 fields appears.

Thanks. I found the reason for the error. A Plug-In to be found at:
https://produkte.web.de/mailcheck/logik/mailcheck-firefox

When installing this Plug-In, it replaces the new-tab by own new-tab which is just a web-search, 4 recommended site links and in the middle the usual 9 fields.
When disabling this Add-On, the New-Tab window then throws this error.
When removing this Add-On while it is disabled, this error is persistent. And that was my problem.
When removing this Add-On while it is not disabled, this error does not appear and the installing and removing procedure fill fix this problem. 

I can now reproduce the bug with the steps just mentioned:
Install this Plug-In, deactivate this Plug-In and de-install then this Plug-In.

Plugins are Flash, Java, quicktime.The name confusing is the reason why I wanted to be sure that you tried it with disabled extensions.

The extensions seems to change the option browser.newtab.url .
You can manually correct it via about:config , the default value is about:newtab

I guess that it does some cleanup if you deinstall it but this cleanup can not be performed if it's already disabled.
