This is probably a stupid question. Firefox is rather rigid, as Internet Explorer is to be known to activate virusses without a problem.
But for my English classes I need eSpeak without the command screen. The program is run local, but I use HTML with javascript.
This is my code:
netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
var localFile = Components.classes["#mozilla.org/file/local;1"].createInstance(Components.interfaces.nsILocalFile);
var process = Components.classes["#mozilla.org/process/util;1"].createInstance(Components.interfaces.nsIProcess);
var args = new Array('-vmb-en1',"Say something");
localFile.initWithPath('C:\\WINDOWS\\espeak.exe');
process.init(localFile);
process.run(false, args, args.length);
I want to hide the prompt in Firefox.
Internet Explorer does what I want with:
try{var speak = new ActiveXObject('WScript.Shell');} catch(err){}
speak.Run('espeak -vmb-en1 "Say something"',0);
Any other suggestion to change the code is welcome.
I think your (and many other people) problem is this one : https://developer.mozilla.org/en-US/docs/Bypassing_Security_Restrictions_and_Signing_Code
But i don't know how to do now !!

How can i create ActiveX Object in java script using asp.net.what i need requirements to create that ActiveX object if i use any DLL to create that object and how can i create can anyone provide description of to create ActiveX object
My Tried code is:
<script lang="javascript" type="text/javascript">
function getSize()

var d = document.getElementById('b').value;
var e = oas.getFile(d);
var f = e.size;
return(f);
}
function checkFileType()
{
var path = document.getElementById('file1').value;
var Index = path.lastIndexOf(".");
var length = path.length;
var filetype = path.substring(Index,length)
if ((filetype == ".doc") ||(filetype == ".pdf") ||(filetype == ".jpg") ||(filetype == ".gif") ||(filetype == ".xls")||(filetype==".odt"))

Can anyone tell me to how can i create ActiveX object properly and what i need setting and which DLL's i use and all can anyone help me out.
Thank You
This validation is not a supported method in all the browsers.
Anyway, for IE9 or below (where .files is not supported) you can use this. To use this method, you will need to enable activex object in IE.
Go to Internet Options->Security Tab. Select trusted website, and click Sites button. It will give you an option to add the url. Add the url of your site, and save. Then click on the button saying "custom levels". It will open a list of options. Find the one saying "Initialize and script activex controls not marked as safe" and enable it.
Save and close the dialog boxes, and refresh your webpage.
Edit:
Few notes:
This is extremely unsecure method, so I would suggest improving compatibility and saying no to anything below IE9.
Secondly, this is something you have to enable on every single user's machine. Otherwise, that line will always throw an exception.
So, if you have to stick to IE8 or lower, and have control over your userbase, then only use this. Otherwise, just use flash upload method for IE browsers. Your users might hate installing flash, but there is nothing you can do.
P.S. I was doing this same thing about an hour ago. Lucky for you, I did all the research. :)
Edit: On a secondary note, can someone help me figure out how to get rid of XML dataislands without major rewrite? That is the only thing stopping me from saying goodbye to IE6.
This is a really strange one. Our company has has an InDesign script that, near the end, calls Acrobat (by way of Applescript) to open a PDF file, replace a page in it, then save the file and close it. We've been using this script for over a year and a half now with no issues on 8 of the 9 computers we have. That last one, however, is giving me an odd message when it tries to open and save the file.
To be clear, all 9 computers are Macs, all running OS X 10.9.5 Mavericks. The script is on a central server, so they're all using the same file:
var unlockCover2014 = app.trustedFunction(function (fName, fPrefix)
{
app.beginPriv();
var folderPrefix = fName.match(/^.*?(?=JOBS)/);
console.println("fName is " + fName);
console.println("folderPrefix is " + folderPrefix);
var myDoc = app.openDoc(folderPrefix + "Product Templates/ProofCoverNew/proof_cover_2014.pdf");
myDoc.replacePages(0, fName, 0, 0);
myDoc.saveAs(fName);
myDoc.closeDoc(true);
app.endPriv();
});
This file is stored in the correct folder to be a Folder-level script. 8 of the computers work through this without any trouble whatsoever. The 9th, however, puts this into Acrobat's Javascript console:
fName is /ArtDept/ArtDept/JOBS/425000-425999/425000 Folder/425000_cover.pdf
folderPrefix is /ArtDept/ArtDept/
RaiseError: This file is already open.
Doc.saveAs:9:
===> This file is already open.
I do not understand why this computer, alone, thinks that the PDF files are open already. The problem that arises from this is that, when the main InDesign script is done running, two documents are still open in Acrobat, and the one it's supposed to save does not get saved.
Any ideas about what's going on here?
I did finally discover what the problem was. I feel a bit silly about how (almost) obvious it is, but perhaps it might help others in my situation.
I disabled the line in the main InDesign script that was calling Acrobat, figuring I'd come back to that problem later after I dealt with some other issues. When I did so and ran the main script again, I discovered that Acrobat does, in fact, already open up a copy of that cover sheet PDF sometime during the execution of the main script! I was shocked, at first, but then I did a headdesk when I quickly realized the cause:
InDesign on this computer is set, by default, to automatically open a PDF after exporting it.
So, I just added a short line to the part of my code that sets the PDF Export Preferences to turn that feature off:
with (app.pdfExportPreferences)
{
pageRange = proofRange;
if (multiColor) pageRange = colorTable.toString();
useSecurity = true;
disallowChanging = true;
disallowCopying = false;
disallowDocumentAssembly = true;
disallowExtractionForAccessibility = false;
disallowFormFillIn = true;
disallowHiResPrinting = false;
disallowNotes = true;
disallowPlaintextMetadata = true;
disallowPrinting = false;
changeSecurityPassword = "(NOPE)";
viewPDF = false;
}
It's the viewPDF line at the end. (Sorry, I don't think I can highlight it with markdown.) I do feel silly that I overlooked such a semi-obvious cause, but I hope this might help someone else who is experiencing a similar issue. Thanks for trying to help anyway, #Loic.
Is it possible that the Acrobat script is ran while InDesign has not totally ended writing the PDF File if this is what we are talking about ? Or maybe there are some network latencies that make the file not reachable for the moment.
I would advice using a delay to (in)validate that theory.
delay 3
On another end, why do you need to replace file. I mean can't this be thought in InDesign Scripting Scope only ? Just curious.
I´m working on a big angular.js project.
Now, I´ve to profile some pages about the performance.
With the console.log of the project I´m looking for the performance problems.
I miss if console.log can output the current time (yes, I know in Chrome you can set up).
Is there a way (like in log4java) to format the output?
Thanks in advance,
Be careful, the console object should not be activated in production mainly because it can breaks the code for some users (for example IE8 or less users).
But if you want to test on a tool that you know, you can use the Web API interface which provides some useful method on this object:
https://developer.mozilla.org/en-US/docs/Web/API/Console
(This doc is from the Mozilla Developer Network (MDN) and therefore mainly applies to Firefox, but at the end of that page you can find links to the corresponding docs for the IE, Chrome and Safari DevTools as well as Firebug).
For example, you can use the time() method for your use case:
console.time("answer time");
// ... some other code
console.timeEnd("answer time");
Outputs something like this:
You could try something like this:
console = window.console ? console : {};
native_log = console.log;
window.console.log = function myConsole() {
// Cannot log if console.log is not present natively,
// so fail silently (in IE without debugger opened)
if (!native_log)
return;
var args = Array.prototype.slice.call(arguments);
args.unshift(new Date());
native_log.apply(console, args);
}
console.log('hello'); // Date 2014-12-02T14:14:50.138Z "hello"
Of course, you would not let the new Date() as is, but it gives you the idea.
I really need a way to copy some text to the OS clipboard in Firefox.
Know it is easy in IE and not possible in Chrome and Opera unless flash is used. Because of different reasons I am unable to use the flash solution!
Had it working in the past but now the netscape.security.PrivilegeManager.enablePrivilege is protected as far as I can figure out (since ver. 17).
It looks as if it is still possible according to this article:
https://developer.mozilla.org/en-US/docs/Using_the_Clipboard
Believe it is still necessary to enable the possibility in the user.js file like this
user_pref("capability.policy.policynames", "allowclipboard");
user_pref("capability.policy.allowclipboard.sites", "http://");
user_pref("capability.policy.allowclipboard.Clipboard.cutcopy", "allAccess");
But how shall I do it? Have made some test without great success and think there is no guide on the web that explain how it shall be done in a generic way. E.g. a simple guide about how to enable javascript access to the clipboard. Hopefully also a guide that can be used by the novice user. Like to do it and post it here but need a working solution first.
According to the web there are 2 solutions for copy to clipboard;
document.execCommand("copy", false, null)
and
var gClipboardHelper = Components.classes["#mozilla.org/widget/clipboardhelper;1"].getService(Components.interfaces.nsIClipboardHelper);
gClipboardHelper.copyString("Put me on the clipboard, please.");
Both generate a failure with my first try.
The solution below need the user to press CTRL+C and I need a solution where the text shall copy based on the press of a button (many on a single page).
https://stackoverflow.com/questions/4344325/copy-to-clipboard-on-firefox-and-google-chrome/11346026#11346026
My old solution was like this:
var clip = Components.classes['#mozilla.org/widget/clipboard;1'].createInstance(Components.interfaces.nsIClipboard);
if(clip)
{
var trans = Components.classes['#mozilla.org/widget/transferable;1'].createInstance(Components.interfaces.nsITransferable);
if(trans)
{
var str = new Object();
var len = new Object();
var str = Components.classes["#mozilla.org/supports-string;1"].createInstance(Components.interfaces.nsISupportsString);
if(str)
{
var clipid=Components.interfaces.nsIClipboard;
if(clipid)
{
str.data = cliptext;
trans.addDataFlavor('text/unicode');
trans.setTransferData("text/unicode", str, cliptext.length*2);
clip.setData(trans, null, clipid.kGlobalClipboard); // No return value
return 0;
}
}
}
}
Components.classes is undefined in unprivileged code (not add-on etc) so I do not believe any solution with this will work any more. One option is to make an add-on that will execute in privileged code area and send the text that shall be copied to this add-on for it to handle the copy to the OS clipboard (nice new possible project).
This only leave document.execCommand("copy", false, null) in the field as a stand alone solution.
Tried this code and it does not copy anything to the OS clipboard - but do not generate any errors btw.
var pre = document.getElementById('pcryptcopytext');
if(!pre)
{
pre = document.createElement("pre");
pre.setAttribute('id', 'pcryptcopytext');
pre.setAttribute('style', 'opacity: 0; position: absolute; top: -10000px; right: 0;');
document.body.appendChild(pre);
}
pre.innerHTML = cliptext;
pre.contentEditable = true;
//pre.unselectable = "off";
//pre.focus();
if (document.createRange)
{
var rng = document.createRange();
rng.selectNodeContents(pre);
document.execCommand("copy", false, null);
document.body.removeChild(pre);
}
So, anybody got a working solution?
Looks like this is not supported any more, and there is no replacement :(

Maybe making some noise in a Firefox bug will help us get a (safe) solution.
Solved by creating a Firefox Add-on that exposes the clipboard object: https://github.com/myplaceonline/myplaceonline_ffclipboard
Example:
if (window.ffclipboard) {
window.ffclipboard.setText("clipboard text");
}
You can use firefox navigator object
navigator.clipboard.writeText("text you want to copy").then(() => {
// on success
}, (e) => {
// on error
});
document.execCommand("copy");
Is it possible, using javascript, to control an overlay firefox extension? I've extracted the contents of the extension and have identified what functions/methods I need to run, but they are not accessible within the scope of the console.
Thanks in advance for any ideas.
Yes it possible to interact with other add-ons, given the right circumstances.
My test case here will be com.googlecode.sqlitemanager.openInOwnWindow(), which is part of the SqliteManager addon.
In newer builds (I'm using Nightly), there is the Browser Toolbox. With it is is as simple as opening a toolbox and executing com.googlecode.sqlitemanager.openInOwnWindow() in the Console.
You may instead use the Browser Console (or any chrome enabled WebDev Console for that matter, e.g. the Console of "about:newtab"). But you need some boilerplate code to first find the browser window. So here is the code you can execute there: var bwin = Services.wm.getMostRecentWindow("navigator:browser"); bwin.com.googlecode.sqlitemanager.openInOwnWindow()
Again, enable chrome debugging. Then open a Scratchpad and switch to Chrome in the Environment menu. Now executing com.googlecode.sqlitemanager.openInOwnWindow() in our Scratchpad will work.
You may of course write your own overlay add-on.
As a last resort, patch the add-on itself.
Bootstrapped/SDK add-ons: you can load XPIProvider.jsm (which changed location recently) and get to the bootstrapped scope (run environment of bootstrap.js) via XPIProvider.bootstrapScopes[addonID], and take it from there (use whatever is in the bootstrap scope, e.g. the SDK loader).
Now about the right circumstances: If and how you can interact with a certain add-on depends on the add-on. Add-ons may have global symbols in their overlay and hence browser window, such as in the example I used. Or may use (to some extend) JS code modules. Or have their own custom loader stuff (e.g. AdBlock Plus has their own require()-like stuff and SDK add-ons have their own loader, which isn't exactly easy to infiltate)...
Since your question is rather unspecific, I'll leave it at this.
Edit by question asker: This is correct, however I figured I'd add an example of the code I ended up using in the end, which was in fact taken directly from mozilla's developer network website:
In my chrome js:
var myExtension = {
myListener: function(evt) {
IprPreferences.setFreshIpStatus(true); // replace with whatever you want to 'fire' in the extension
}
}
document.addEventListener("MyExtensionEvent", function(e) { myExtension.myListener(e); }, false, true);
// The last value is a Mozilla-specific value to indicate untrusted content is allowed to trigger the event.
In the web content:
var element = document.createElement("MyExtensionDataElement");
element.setAttribute("attribute1", "foobar");
element.setAttribute("attribute2", "hello world");
document.documentElement.appendChild(element);
var evt = document.createEvent("Events");
evt.initEvent("MyExtensionEvent", true, false);
element.dispatchEvent(evt);
Update for Firefox 47 and up
Things changed drastically in Firefox 47. This is the new way to access it.
var XPIScope = Cu.import('resource://gre/modules/addons/XPIProvider.jsm');
var addonid = 'Profilist#jetpack';
var scope = XPIScope.XPIProvider.activeAddons.get(addonid).bootstrapScope
Old way for < Firefox 47
Update for methods of today
Typically you will do so like this:
If i wanted to get into AdBlocks scope, I check AdBlock id, it is {d10d0bf8-f5b5-c8b4-a8b2-2b9879e08c5d} so I would go:
var XPIScope = Cu.import('resource://gre/modules/addons/XPIProvider.jsm');
var adblockScope = XPIScope.XPIProvider.bootstrapScopes['{d10d0bf8-f5b5-c8b4-a8b2-2b9879e08c5d}'];
You can now tap into anything there.
Another example, I have an addon installed with id NativeShot#jetpack
I would tap into it like this:
var XPIScope = Cu.import('resource://gre/modules/addons/XPIProvider.jsm');
var nativeshotScope = XPIScope.XPIProvider.bootstrapScopes['NativeShot#jetpack'];
if you do console.log(nativeshotScope) you will see all that is inside.
