webauthn yubico example not working on Firefox - javascript

I'm trying to run the this project: https://github.com/YubicoLabs/java-webauthn-passwordless-workshop
On Chrome and Edge it works fine, but with Firefox I can't register my Yubikey (no Error Log, Key does not light up and waits for a touch) or authenticate with a previously registered Key (Key lights up and notices the touch)(DOM Exception: An attempt was made to use an object that is not, or is no longer, usable)
Now I'm quite curious what is causing this behaviour. Is it a Problem with my Firefox config? (aboout:config wenbauthn variables are true) Or is something wrong with the project?
Using:
Win 10
Firefox 80.0.1 (also tried 71)

Using ios_webkit_debug_proxy on linux

I am trying to use the description from https://github.com/google/ios-webkit-debug-proxy to debug my website on iPhone (Running iOS 7.1.2).
I compiled ios_webkit_debug_proxy, and is running it with
ios_webkit_debug_proxy -d
I then start google-chrome and point it to localhost:9222/ which shows my iPhone, and the website it is currently visiting. I then copy/paste the link address(chrome-devtools://devtools/bundled/devtools.html?host=localhost:9222&page=1) into a new chrome tab, and then I get a debug window which shows
Elements,Network,Sources,Timeline,Profiles,Resources,Audits,Console.
But none of theese buttons shows any real content. There is no dom. No javascript. No output in the console view. No activity in the network. Its like debugging a empty view.
My ios_webkit_debug_proxy -d console, shows a new message, each time my iPhone
visits a new website. But it shows no other activity. THe messages start with something like
ss.remove_fd(7)
ss.recv fd=13 len=0
ss.remove_fd(13)
ss.recv fd=12 len=221
wi.recv[221]:
And they do just as far as I can see, contain the website url, but not any real content from the website.
The console I started chrome from, shows the message:
"Uncaught TypeError: Cannot read property 'frame' of undefined", source: chrome-devtools:/
I am using Fedora 20.
Does anyone have any clue why this does not work ?
Thanks
It isn't clear to me if you switch the browser to localhost:9222/ after you get a pair of lines like:
Listing devices on :9221
Connected :9222 to Will's iPhone (8a48ac86edd4f299xxxxxxxxxxxxxxx)
if you don't see the second line, then it means that probably you have issues with usbmuxd or libimobiledevice.
I've had some issues myself with the proxy, but then i was able to use it with satisfaction. In my experience, there are few things that make the life easier:
1) Run the usbmuxd as root and possibly with options -fv so that it doesn't detach from the tty and you see what happens. In my Debian installation it is run wit a system user in background;
2) In order to avoid the crash of the proxy when an unhandled exception happens don't use the debugger release of your chrome/chromium but instead use a pretty older one https://chrome-devtools-frontend.appspot.com/static/18.0.1025.99/devtools.html (see https://github.com/google/ios-webkit-debug-proxy/issues/63)

Why does accessing the localStorage object in Internet Explorer throw an error?

I'm working on a client issue where Modernizr unexpectedly does not detect the support for the localStorage object in Internet Explorer 9. My page correctly uses the HTML 5 doctype (<!DOCTYPE html>) and the developer tools report the page has a Browser Mode of IE9 and a Document Mode of IE9 standards so I would expect this to work.
I've debugged into the following try/catch block in Modernizr and discovered a JavaScript error is thrown as soon as the localStorage object is accessed.
tests['localstorage'] = function() {
try {
localStorage.setItem(mod, mod);
localStorage.removeItem(mod);
return true;
} catch(e) {
return false;
}
};
On some machines the message of the JavaScript error is The system cannot find the file specified.. On others it is just Invalid argument. and Internet Explorer blocks for exactly 5 minutes before it throws the error.
What is causing accessing the localStorage object to throw an error here on Internet Explorer?
I've discovered if the lowest level subdomain matches one of the reserved device names as documented at Restrictions on the File Mask and File Name Properties on Internet Explorer then accessing the localStorage object will throw an error.
This problem is likely happening because internally Internet Explorer is attempting to access the file system using a reserved device name when accessing the localStorage object in order to satisfy the Storage object initialization steps.
It's certainly very much an edge case but if your page is comes from a server whose lowest level subdomain is exactly any of con, prn, aux, clock$, nul, com1, com2, com3, com4, com5, com6, com7, com8, com9, lpt1, lpt2, lpt3, lpt4, lpt5, lpt6, lpt7, lpt8, or lpt9 (e.g. http://prn.example.com) then this could well the reason why you are seeing this problem.
Choosing a lower level subdomain that wasn't a reserved device name in this situation solved the problem.
We hit a similar issue because we ran CCleaner on the machine.
To solve:
Internet Options -> Browsing History -> Delete:
Make sure to check all options except the very first one (Preserve Favorite website data).
We were able to fix, then reproduce this issue by using CCleaner again, then fix again.

Access Denied for localstorage in IE10

Yesterday I installed Windows 8 and am now trying to understand why I am getting an "Access Denied" message when accessing localstorage. The page is being served on the same PC with the browser (http://localhost). My feeling is that one of the security settings in IE 10 is wrong, but I haven't figured out which one.
The line of JavaScript code triggering the error is:
if(window.localStorage.getItem('phone') == null)
The code works fine in the latest version of Chrome.
Our users were having issues with web sites using the LocalStorage feature (including Twitter) on Windows 8 with IE 10. When accessing one of these sites with the F12 Developer Tools open, a SCRIPT5: Access is denied message appeared on the console.
After working with Microsoft support, we identified the cause. It turned out to be a problem with the settings on the C:\Users\username\Appdata\LocalLow folder in their user profile.
Each folder on your computer has an integrity setting. More information about the purpose of this setting is here: http://msdn.microsoft.com/en-us/library/bb625964.aspx
The integrity setting on the AppData\LocalLow folder (and its subfolders) in each user's profile is supposed to be set to "Low" (hence the name). In our case, the integrity level was not set correctly on this folder. To rectify the problem, run the following command in a command prompt window:
icacls %userprofile%\Appdata\LocalLow /t /setintegritylevel (OI)(CI)L
(If there is more than one user account on the computer and the other users are having the same issue, the command needs to be run under each affected user's account.)
As for how this setting got changed in the first place? In our case, it was caused by a problem in the customized Windows 8 image we deployed to our workstations. For others that are having the issue, my research has revealed that the use of a "system cleaner" utility may be to blame.
Doubtless there might be many causes of the same symptoms, but here is what fixed this issue for me.
I had just one of many Windows 7 PCs with IE11 exhibiting the symptom of "Access Denied" on attempting any JavaScript involving window.localStorage from otherwise reputable and well-behaved web sites. Use of Process Explorer revealed that the proximal cause was an ACCESS DENIED when taskhost.exe (acting on behalf of Internet Explorer) tried to open DOMStore\container.dat for Generic Read-Write. In fact, it was worse than that: if I deleted container.dat, the same ACCESS DENIED occurred, even through the file did not exist any more. And, if I deleted the (hidden) DOMStore folder, when taskhost.exe attempted to recreate it, that received ACCESS DENIED as well.
After two days of chasing false leads, the final solution was this:
The registry entry:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\LowCache\Extensible Cache\DOMStore\CachePath
(do note the LowCache in that string) was incorrectly set to:
%USERPROFILE%\AppData\Local\Microsoft\Internet Explorer\DOMStore
when it should be:
%USERPROFILE%\AppData\LocalLow\Microsoft\Internet Explorer\DOMStore
with the consequence that low-integrity localStorage requests were being directed to medium-integrity regions of AppData disk storage, thus generating ACCESS DENIED errors, and killing the use of JavaScript window.localStorage.
This registry entry must have been wrong for many years: perhaps a side-effect of enthusiastic take-up of buggy platform previews and so on. This error survived a total removal and re-installation of IE11.
There is a similar-looking registry entry for the medium-integrity cache:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\5.0\Cache\Extensible Cache\DOMStore\CachePath
and that is correctly left as:
%USERPROFILE%\AppData\Local\Microsoft\Internet Explorer\DOMStore
and should not be changed.
Try enabling the Enhanced Protected Mode in the IE settings, under the Advanced tab, in the Security sub-list. This enables the Microsoft XSS filter. I had similar issues when logging into SE, and fetching google+ notifications, and my first workaround was starting IE with admin privileges. But I think the EP mode will do the trick in your case too.

Mark Russinovich always says: "when in doubt, use Process Monitor":
localStorage data gets stored in XML files in the following folder:
C:\Users\[USERNAME]\AppData\Local\Microsoft\Internet Explorer\DOMStore
A profile of the file activity while reproducing the issue can tell you if the problem is caused by missing file access permissions or maybe even an anti-virus program.
I can reproduce the error by adding the read-only attribute to "DOMStore\container.dat". You should check if all file/folder permissions and attributes are set correctly. On my machine, admins and my own account have full permission for the mentioned folder.
Go to Tools/Internet Options/Advanced and under 'Security' select 'Enable DOM Storage' checkbox. This should fix the problem
I added the websites involved to the Trusted Sites section of IE and have not received the error again.
In addition to the already excellent answers here, I'd like to add another observation. In my case, the NTFS permissions on the Windows %LOCALAPPDATA% directory structure were somehow broken.
To diagnose this issue. I created a new Windows account (profile), which worked fine with the localStorage,so then I painstakingly traversed the respective %LOCALAPPDATA%\Microsoft\Internet Explorer trees looking for discrepancies.
I found this gem:
C:\Users\User\AppData\Local\Microsoft>icacls "Internet Explorer"
Internet Explorer Everyone:(F)
I have NO idea how the permissions were set wide open!
Worse, all of the subdirectories has all permissions off. No wonder the DOMStore was inaccessible!
The working permissions from the other account were:
NT AUTHORITY\SYSTEM:(OI)(CI)(F)
BUILTIN\Administrators:(OI)(CI)(F)
my-pc\test:(OI)(CI)(F)
Which matched the permissions of the parent directory.
So, in a fit of laziness, I fixed the problem by having all directories "Internet Explorer" and under inherit the permissions. The RIGHT thing to do would be to manually apply each permission and not rely on the inherit function. But one thing to check is the NTFS permissions of %LOCALAPPDATA%\Microsoft\Internet Explorer if you experience this issue. If DOMStore has broken permissions, all attempts to access localStorage will be met with Access Denied.
This issue may also be caused by having missing or corrupted registry entries. If a reset does not resolve the issue, the LocalLow folder has the correct integrity level, and the DOMStore registry value is correct, run the below commands to re-register IE in the profile:
32 Bit OS:
C:\WINDOWS\system32\ie4uinit.exe -BaseSettings
64 Bit OS:
C:\WINDOWS\system32\ie4uinit.exe -BaseSettings
C:\Windows\SysWOW64\ie4uinit.exe -BaseSettings

web workers not working in firefox 8, works in firefox 7

I am using library called arbor.js(beautified). It contains the following line of code,
i = new Worker(<path to arbor.js>);
At this point an error is thrown, and the following message is reported in Firebug,
"Could not get domain!"
The line which gives this error is 258. The arbor_path() function on that line returns "js/", so effectively function called is i = new Worker("js/arbor.js").
This used to work perfectly in Firefox 7. Does anybody know how to solve it, or what the problem could be?
You're running into https://bugzilla.mozilla.org/show_bug.cgi?id=683280
It'll be fixed in Firefox 9 in about a month....
I came across the same thing, however I only noticed the problem on one of my computers, and not the other (both running Firefox 8), so I started to explore a little bit. It turns out, the computer the workers were working on is using a subdomain of localhost (and modified HOSTS file). I just tested it out as simply as I could think of, just adding localhost.com to the HOSTS file, and accessing the site through that and the workers are doing ok with it. I didn't create any virtual hosts or directories, just mapped localhost.com to 127.0.0.1. If you are running on Windows (or otherwise can do the same kind of mapping) you might want to give that a try as a temporary solution.
Edit: In response to chinmayv's comment: Something I noticed I have set in the HOSTS file is the IPv6 version of the local IP address, so there is both: ::1 localhost and 127.0.0.1 localhost, as well as the one to get the worker running on FF8 127.0.0.1 localhost.com. I don't know why this would matter, however. I just did a fresh install of Apache, so I don't think there is any setting that could account for the difference in behavior. Are you still getting the 'Could not get domain!' error? Maybe there is an absolute URL in the script somewhere that is throwing it off?

enabling Firefox 5.0 javascript dump()

I'm going through firefox extension writing bootcamp and somewhere along the way the video's author is speaking about switching browser.dom.window.dump.enabled in about:config to true. This option is no longer present in firefox 5.0. From what I read during my google searches, in ff 4.0 you had to create this preference yourself, and it seems like in firefox 5.0 it doesn't work anymore - I can't seem to dump information to firefox error console any more (regardless of whether console2 is enabled or not).
Relevant code:
Here's how I'm launching the browser:
/usr/bin/iceweasel -profile /some/path -no-remote -jsconsole
And here's the code that only shows the alert, without writing anything to the error console:
onCommand: function(event) {
toJavaScriptConsole("toJavaScriptConsole: hello world");
dump("Hello world!\n");
alert("Hello world!\n");
}
Any idea what I can do to have working dump() called from the ff extension I'm working on in firefox 5.0?
You confused the error console with plain linux console - if you run firefox from terminal you should see the dumps right there.
in-depth explanation
This preference was never present by default - you always had to create it and set to true. Also, the output doesn't go to Error Console, it is rather visible in the terminal you start Firefox from. If you happen to test on Windows you should specify -console command line flag to open a terminal window for the output, on Linux simply starting Firefox from a terminal window will do.
