I am running the latest versions of Firefox and Adblock. I have ruled out any other plugins I have installed at being at fault for this error. When Adblock is enabled in the Extensions window, and either Enabled or Disabled it Adblock's own preferences window, it causes this sites Server Status, which is the ServerSpy Mini Monitor script, to not render.
http://www.snarkcafe.net/ look for it on the right side.

Heres the source for the MiniMonitor.
| Code: | <!-- ServerSpy Mini Monitor Div -->
<div id="ssmini73589" class="ssminiloading">Loading Mini Monitor..<br>Please Wait</div>
<!-- server spy mini end -->
<!-- serverspy.net mini monitor logic [ for monitor 5311 ] start -->
<script language="javascript">ssMiniId = 'ssmini73589';</script>
<script language="javascript" src="http://share1.serverspy.net/cgi-bin/monitor.js?mid=73589"></script>
<!-- serverspy.net mini monitor logic [ for monitor 5311 ] end -->
<!-- Server Spy Mini End --> |

I loaded up the page, and everything works like a charm. |

CPeanutG: When loading your page with Adblock enabled, the JavaScript Console prints out the following error messages:
| Code: | Warning: reference to undefined property plugin.SetWindow
Source File: javascript: function jsScriptObject(obj) { this.wrappedJSObject = obj; } jsScriptObject.prototype = { evaluate : function(expression) { return new jsScriptObject(eval(expression)); } }; var plugin = document.embeds['smon73589']; plugin.SetWindow(new jsScriptObject(window),2039527021);
Line: 1 |
| Code: | Error: plugin.SetWindow is not a function
Source File: javascript: function jsScriptObject(obj) { this.wrappedJSObject = obj; } jsScriptObject.prototype = { evaluate : function(expression) { return new jsScriptObject(eval(expression)); } }; var plugin = document.embeds['smon73589']; plugin.SetWindow(new jsScriptObject(window),2039527021);
Line: 1 |
When I navigate to another URL, the Console says this:
| Code: | Attempt to load a javascript: URL from one host
in a window displaying content from another host
was blocked by the security manager. |
That said, the tables are loaded properly when Adblock is disabled. Strange, but I'm not entirely sure what Adblock is doing to cause this, or if it should even be considered Adblock's fault. Some of the JavaScript there is pretty atrocious: it writes VBScript even when it knows the browser is Firefox, it tests for variables before setting/defining them... as far as I can tell, the actual code that writes the table is embedded in the "rendering" swf? I can't really see what's going wrong, so I have no idea where to begin looking for what to fix, if anything.
The code includes this comment:
| Code: | | // Fix for Flash security issue where javascript can't talk to flash |
so it sounds like they're aware of this issue in general, but aren't detecting it correctly when Adblock is installed. |

URL where this happens:
http://www.newscientist.com/article.ns?id=dn7195
Image that shows how the page looks like when it's incorrectly rendered. Just to show you that I'm not making things up. (texts are over the links on the right)
http://personal.inet.fi/koti/aggro/text_over.png
And here is what it should look a like:
http://personal.inet.fi/koti/aggro/not_over.png
Steps to repeat the behaviour:
0. You should have Adblock installed and enabled
1. Close all Firefox windows and open a brand new one.
2. Select Tools -> Options -> Privacy -> Clear cache
3. Go to URL: http://www.newscientist.com/article.ns?id=dn7195
* Page should render incorrectly.
5. Press refresh
* Page should render correctly
6. Close your browser window and go again to the given url.
* Page should render correctly.
7. Disable adblock
8. Restart browser
9. Clear cache
10. Go to given URL
* Page should render correctly.
So only if you don't have the page in your cache and you have adblock enabled, the page will be rendered incorrectly. I have not yet failed once repeating this behaviour. I will now check does it matter what kind of blocks I'm using...
System information:
I have Firefox 1.0.2 on Windows 2000 + SP4
Adblock version: 0.5.2.039 |

I have done more research. If you test the above, you should have only one filter (propably it works also if you many as it worked with me), but this is the critical filter:
http://adserver.*
With adblock having only this filter, the bug can be reproduced. With empty or with random filters the bug won't appear, so this propably affects the page rendering process somehow.
Please see if you can fix this or if you need more info about this bug. This is the best I could do to tell you how to reproduce this bug. |

Guest: With our latest code (unreleased) this appears fixed.
Excellent work with instructions/testcase, by the way. If only more users could provide such detailed instructions for bug reports... =/ |

Got any idea, why the fixed version is not available via Firefox tools -> extensions -> update? Who desides when new versions are put there and is there anything I can do to speed it up?
I know I could download and install the extensions directly from here, but I would prefer to use the update-tool to keep all extensions updated. If only that thing would actually give updates ;) |
