User-Agent: Mozilla/5.0 (Windows; U; Win98; rv:1.7.3) Gecko/20040913 Firefox/0.10.1 Build Identifier: Firefox/1.1 The symantec NAV package comes with a popup blocker that redefines the windows object. It seems javascript errors, like using nonexistant variables or unterminated strings, do not show up anymore inside the are bracketed by the NAV scripts. Actually I have no idea whether it is NAV or version 1.1, I'm just naming suspects Reproducible: Always Steps to Reproduce: 1.write a javascript with an error inside a webpage 2.load page while the NAV popup blocker is running 3.look in console Actual Results: No errors from the webpage. I was using DTD HTML4.1 strict, if that makes a difference Expected Results: give diagnostics for debugging

Seems more like a symantec bug than a Firefox one. Why not contact their support? What is the link to the product so we don't have to go searching for something that might be what you are using. Are you really using such an old version of Firefox? You should upgrade to 1.0.1 immediately. Why is your ua string below Firefox/0.10.1 on Win98 and your build identifier Firefox 1.1 but this bug shows Windows XP? What extensions do you have installed? Can you give an example of a page where you think there is an error that is not reported in the javascript console? Please include a link to a page which illustrates the issue or attach the full page to this bug using "Create New Attachment" link above.

I am not using the same computer at work. I upgraded now to FF 1.0.1 rv: 1.7.6 I think I reproduced the problem, see: http://www.armyofanubis.net/hylZee/test.html Basically, the symantec pop up blocker is a script inside <script language="javascript"> , while the script I am working on is inside <script language="JavaScript" type="text/JavaScript"> errors in the second script don't show. maybe the error handlers can handle only one type of script or so .. or maybe it is the DTD strict, which symantec doesn't follow. Still the javascript is parsed, si it should throw errors If I do the following in either head or body: <script language="JavaScript" type="text/JavaScript"> <!-- alert('test'); var x =a; var a="; //--> </script> them at first it wont show errors about unterminated strings, then if one comments out the string error, it shows the alert, but the warning about "a unitialized" is missing .. Here is the Symantec script, for completeness: <script language="javascript"> <!-- function SymError() { return true; } window.onerror = SymError; var SymRealWinOpen = window.open; function SymWinOpen(url, name, attributes) { return (new Object()); } window.open = SymWinOpen; //--> </script>
I have just stumbled into this. See http://www.cs.ucl.ac.uk/staff/W.Langdon/javascript_hang.html My example shows javascript sliently dying after a java script error. The non-javascript HTML parts of the page are displayed ok. Note this applies to Firefox and a very new build of deer park: Deer Park 1.0+ alpha Gecko/2005/20050717 Firefox/1.0+ My PC is running WindowsNT 5.1 rv:1.8b4 Service pack 2 As far as I know, it is _not_ running symantec or any other popup blocker, except the nice goodies that come by default in Firefox/DeerPark Ok I should not write sloppy javascript code with bugs in it but it is very helpful to get some sort of error reported rather than everything stoping and the browser giving no clue as to what has happened.

More information. I _do_ get an error on the JavaScript Console when I load http://www.cs.ucl.ac.uk/staff/W.Langdon/javascript_hang.html if I do it from another PC! May be all this should be under a new bug report? Ok so what is different about this PC? Number one it does not and never has had deer park on it. Firefox 1.0.2 Mozilla 5.0 WindowsNT rv:1.7.6 gecko 20050321 firefox/1.0.2 The error on the JavaScript console is Error: nonexistant is not defined Source File: http://www.cs.ucl.ac.uk/staff/W.Langdon/javascript_hang.html Line: 27 BTW: when I switch between firefox and deerpark on the orginal PC (windowsNT 5.1) I get a box saying Firefox Update | Incompatible Components | The following components are not compatible with the new version of firefox you have just installed | show java console 0.1 Note this is the Java Console -- not the JavaScript Console. I have ignored this message uptill now. From memory I do not think the "show _java_ console" option appears on the deerpark tools menu. Once again, Many thanks Bill

(In reply to comment #5) Sounds like a bug in the extension <http://showjavaconsole.mozdev.org/>. You can check it out by either using safemode or by uninstalling the extension to see if the JavaScript console works. You can configure the Java plugin to start the console, so this extension really isn't needed imo. mozdev appears to still be down due to the flood...

You can configure the Java plugin to start the > console, so this extension really isn't needed imo. On the original PC; I have run both firefox and deerpark in safemode. I have uninstalled java console extension (in firefox it was greyed out of the tools| extensions menu, which held a message saying "java console 0.1 not compatible with firefox 0.1.0.1" (?hmm not sure I remembered the last version number correctly). None of these changes have made any difference to the bug. I.e. the javascript console still refuses to log anything. I have installed the latest build (gecko/20050712 firefox/1.0+) of deerpark on a third PC. As far as I can tell it is ok, ie the bug is not seen. To try and provoke the error I tried to "sanitize" deerpark and crashed windows. Deerpark javascript console continued to work fine. In the last few weeks I have installed deerpark twice. (I installed firefox sometime near the end of last year). Deerpark has crashed the ialmrnt5 display several times (I have not found a simple/repeatable example worth a bug report). Once again many thanks for your help Bill
(In reply to comment #7) Just a quick update. I have uninstalled deerpark (including deleting files in C:\Program Files\Deer Park Alpha 2\ and reinstalled it (build gecko/20050712). I have deleted everything in C:/.../Local Settings/Temp and C:/.../Local Settings/Termporary Internet Files. I have uninstalled DeerPark (including delete) again and uninstalled Firefox (including deleting files in C:/program files/Firefox...) and reinstalled deerpark. I have rebooted several times. I have tried the new installation in safemode. Always Deer Park refuses to talk to its javascript console. Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b3) Gecko/20050712 Firefox/1.0+ Ps: Netscape 7.2 is still working ok:-) Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.2) Gecko/20040804 Netscape/7.2 (ax) As always any help is most welcome Bill
(In reply to comment #8) More by random chance than judgment, the problem with my PC's installation has been fixed. Please see bugzilla 314571. Once again mnay thanks for all your help. Bill
