231272 - if ActiveX plugin installed then "plugin performed an illegal operation" message when viewing flash

Status: RESOLVED WORKSFORME

(Core Graveyard :: Embedding: ActiveX Wrapper, defect)

Description

[Josh Cockey]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6) Gecko/20040113
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6) Gecko/20040113

These pages worked normally in Mozilla 1.5. This is new to 1.6.  When I dismiss
the dialog box, the page may or may not continue to load depending on which url
I access. The pages probably try to display a popup and popups are disabled but
the same thing happens if popups are enabled.

Reproducible: Always

Steps to Reproduce:
1.Launch browser
2.Enter http://www.wired.com/news/, http://www.speedtv.com/schedule/, or
http://www.washingtonpost.com/wp-dyn/washtech/  
3."Illegal Operation in Plugin" box appears
4.Dismiss dialog box



Actual Results:  
Page continues to load on Wired and Washtech but not on Speedtv
Clicking on a link on the Wired page causes the same msg to pop up when the new
page starts to load.  New page continues to load when dialog box is dismissed.

Expected Results:  
Page should load normally

I uninstalled Mozilla 1.5 before installing 1.6.  Unfortunately, it does not
specify which plugin is having the problem.  These pages worked normally in 1.5.

I'm using w2k sp4 on a p3/450 with 768 Mb and plenty of free HD space.
Javascript and Java are enabled and j2re1.4.1_02 is installed.

reporter: how about at least listing the contents of about:plugins?
also use view-source:<url> and save the page contents, try to build a small
testcase which reproduces the problem. ask irc.mozilla.org #mozillazine for help

I can confirm this bug; it doesn't show up with http://www.wired.com/news/, but
on http://www.heute.de. Same version as reporter, last version known working was
1.4.1.
about:plugins see above (w/o the CSS file).

Addition: Mozilla crashes on quit when the said message had appeared before. The
message says "instruction 0x01143fd4 points to adress 0x614a99e0; action 'read'
not possible" (translated from the German output). A screenshot of the debug
session starting after that will follow (or somebody tells me how I can save the
core dump in W2k/VS6).

I had the same problem.  Visiting sites with flash (like macromedia's website)
causes both mozilla and firebird to display the message

Illegal Operation in Plugin
The plugin performed an illegal operation. You are strongly advised to restart
Navigator.
[] Don't show me this message again during this session.
[ OK ] 

When I quit Mozilla or Firebird, it crashes.

The ActiveX plugin file "npmozax.dll" caused the problem. Once I deleted it,
everything ran smoothly.  Netscape 7.1, by default, installs this plugin. 
Delete it and you will be fine.

I've been seeing this a lot the last few days. Mozilla 1.8a2 Win XP SP2.

There are two seperate problems. One is the existance of this error message
dialog, the second is that it refers to "Navigator".

Found this on one my "error" pages :-

//Detect ActiveX Architecture on Both IE and on Gecko
//Defer to plugin architecture for other browsers

function displayWMP() {
var wmpPlayer = "";

var player = createActiveXObject('WMPlayer.OCX.7');
if(player) {

....etc etc

This is as small as I can get the HTML, I hope it is useful for finding the
problem.

Just noticed that this seems to only happen with the Mozilla Suite, and not with
Firefox.

More info.

The phrase about restarting Navigator comes from :-
xpfe/components/xfer/resources/locale/en-US/downloadProgress.properties#14

This is used by :-
modules/plugin/base/src/nsPluginHostImpl.cpp#6118

Using a DEBUG build, I get the following :-

The procedure entry point
?NS_NewByteArrayInputStream@@YAIPAPAVnsIByteArrayInputStream@@PADK@Z could not
be located in the dynamic link library xpcom.dll.

Also, this problem doesn't happen on Linux.

Just confirmed that this bug still appears in Firefox 0.10.1 with the example URL.
