When I start Mozilla and try to add some sidebar it fails.
But when I try for the second time all is working correctly and sidebar is added.

This is only in the case, when you star Mozilla with hidden sidebar. When you
open the sidebar, all is correct. 

Reproducible: Always

Steps to Reproduce:
1. Start Mozilla (sidebar is hidden)
2. go at
3. click on Install the DevEdge Sidebar Tab

Actual Results:  
Nothing happened, in JS-console is error:

Error: [Exception... "Component returned failure code: 0x80004003
(NS_ERROR_INVALID_POINTER) [nsIRDFContainer.Init]"  nsresult: "0x80004003
(NS_ERROR_INVALID_POINTER)"  location: "JS frame :: 

file:///C:/Program%20Files/ ::
anonymous :: line 138"  data: no]

Source file: file:///C:/Program%20Files/
Line: 138

Expected Results:  
Add sidebar.

The problem is with this line:

container.Init(this.datasource, panel_list);

Seems like something is not initialised when the Mozilla is started with hidden

A observe this problem in M1.4 but I can reproduce it also with some older
Mozilla versions.
Reporter: please download a recent nightly build and try again.
I get a JS window asking me to open my sidebar before trying to install one, so
this has been 'fixed'. What I'm guessing is that this isn't really supposed to work.

I get the error messages in the JS console, but they can be turned of in
Edit->Preferences->Debug->"Show chrome JavaScript errors and warnings".

Oooh, yes, I see it now. But this is hack of

Look to the source of

The question is, if every website which want to add Mozilla sidebar have to
solve this problem or if this could be solved in Mozilla itself.

In the bug #99808 I haven't found anything about opening sidebar before you can
add other.

So I still think this bug could be reopened. Please, reconsider once more.

An quick solution (in same way as is on - i.e. alert
telling user something like 'Try it once more') is simple. I am not Mozilla
hacker, this is only my proposal for quick (but of course not the best) solution.

Alert when failed sidebar adding

Here is my proposal. Display alert to the user when the problem occures.

- Path is only proposal not well formed yet.
