A week ago i think, I started getting warning messages in my google chrome console.
Clearing cache doesn't change anything, the messages disappear only in incognito mode.
Any ideas how to get rid of these warnings ?
I had this problem with the LastPass browser extension. I proved my theory by disabling LastPass and reloading the site in question - the warnings were gone!
I really didn't want to disable the JavaScript and CSS source maps so I have made the following change below:
Pending an update from the LastPass that addresses the issue, I have temporarily fixed this by changing one of the settings in the Extension settings for LastPass.
I had this setting previously set to On all sites, which was injecting the LastPass code on all sites blindly. With this change you need to right click on the Username/Password box to enable last pass, but on the plus side there are no warnings in the console anymore.
I consider this a temporary workaround until either Google or LastPass fix the issue.
EDIT: There is also a checkbox in the settings dialogue for the Console tab itself called Selected context only. Ticking this will remove the warnings and errors from Chrome extensions. Note this setting is not persisted - you'll have to click it each time you open the Dev Tools.
I've just used Chrome Console Filter -chrome-extension. I see everything except chrome-extension output.
For me it was the McAffee Web Advisor Chrome extension - removed and messages gone :)
this worked for me:
Find the path to the extensions. Type this in chrome: chrome://version/ . Look for the profile path. this location is where the extensions are saved.
Open the location with the file explorer. In my case it was something like (AppData\Local\Google\Chrome\User Data\Default\Extensions\hdokiejnpimakedhajhdlcegeplioahd\4.51.0.1_0) The error was with the last pass plugin.
Create the missing maps. In my case it was: sourcemaps/
Note that i only created the empty maps.
All I did is disable my LastPass extension(plugin), clear browsing data, hard reload the page and it works fine.
It might be another plugin for you
You need to open settings from the debug console
Then you disable one of chrome's option (They added it recently)
Just refresh the browser and all ready
I want to integrate Marketo form with my existing website on yii framework.
My code works on all the browsers except Firefox.
Excerpt from my code:
$('#button').click(function () {
var formData = {
'Email': $('#UserInfo_email').val(),
'FirstName': $('#UserInfo_first_name').val(),
'LastName': $('#UserInfo_last_name').val(),
};
MktoForms2.loadForm('//app-ab23.marketo.com', mcId, formId, function (form) {
var myForm = MktoForms2.allForms()[0];
myForm.addHiddenFields(formData);
myForm.onSuccess(function (values, followUpUrl) {
return false;
});
myForm.submit();
});
});
I get error on Firefox only with message
Loading failed for the <script> with source “http://app-ab23.marketo.com/index.php/form/getForm?munchkinId=1111&form=1111&url=http%3A%2F%2Fblox.dev%2Fwizard%2Fmap&callback=jQuery110207175825035737486_1503656391790&_=1503656391791”.
other browsers do the job correctly
note: munchkinId and formId are changed for posting here.
I just had the same issue on an application that is loading a script with a relative path.
It appeared the script was simply blocked by Adblock Plus.
Try to disable your ad/script blocker (Adblock, uBlock Origin, Privacy Badger…) or relocate the script such that it does not match your ad blocker's rules.
If you don't have such a plugin installed, try to reproduce the issue while running Firefox in safe mode.
If you cannot reproduce it in safe mode, it means your issue is linked to one of your plugins or settings.
Otherwise, it might be a different issue. Make sure you have the same error message as in the question. Also look at the network tab of the developer tools to check if your script is listed (reload the page first if needed).
I've just had the same issue - for me Privacy Badger on Firefox was the issue - not adblocker. Posting for posterity
I noticed that in Firefox this can happen when requests are aborted (switching page or quickly refreshing page), but it is hard to reproduce the error even if I try to.
Other possible reasons: cert related issues and this one talks about blockers (as other answers stated).
Today I ran into the exact same problem while working on a progressive web app (PWA) page and deleting some cache and service worker data for that page from Firefox. The dev console reported that none of the 4 Javascript files on the page would load anymore. The problem persisted in Safe mode, so it was not an add-on issue. The same script files loaded fine from other web pages on the same website. No amount of clearing the Firefox cache or wiping web page data from Firefox would help, nor would rebooting the Windows 10 PC. Chrome all the time worked fine on the problem page. In the end I did a restore of the entire Firefox profile folder from a day-old backup, and the problem was immediately gone, so it was not a problem with my PWA app. Apparently something in Firefox got corrupted.
I had the same problem (different web app though) with the error message and it turned out to be the MIME-Type for .js files was text/x-js instead of application/javascript due to a duplicate entry in mime.types on the server that was responsible for serving the js files. It seems that this is happening if the header X-Content-Type-Options: nosniff is set, which makes Firefox (and Chrome) block the content of the js files.
As suggested above, this could possibly be an issue with your browser extensions. Disable all of your extensions including Adblock, and then try again as the code is loading fine in my browser right now (Google Chrome - latest) so it's probably an issue on your end. Also, have you tried a different browser like shudders IE if you have it? Adblock is known to conflict with domain names with track and market in them as a blanket rule. Try using private browsing mode or safe mode.
I ran into the same issue (exact error message) and after digging for a couple of hours, I found that the content header needs to be set to application/javascript instead of the application/json that I had. After changing that, it now works.
VPNs can sometimes cause this error as well, if they provide some type of auto-blocking. Disabling the VPN worked for my case.
If the src is https and the certificate has expired -- and even if you've made an exception -- firefox will still display this error message, and you can see the exact reason why if you look at the request under the network tab.
I had the same issue with firefox, when I searched for a solution I didn't find anything, but then I tried to load the script from a cdn, it worked properly,
so I think you should try loading it from a cdn link, I mean if you are trying to load a script that you havn't created.
because in my case, when tried to load a script that is mine, it worked and imported successfully, for now I don't know why, but I think there is something in the scripts from network, so just try cdn, you won't lose anything.
I wish it help you.
I ran in the same situation and the script was correctly loading in safe mode. However, disabling all the Add-ons and other Firefox security features didn't help. One thing I tried, and this was the solution in my case, was to temporary disable the cache from the developer window for this particular request. After I saw this was the cause, I wiped out the cache for that site and everything started word normally.
I've had the same problem and the culprit was the "I don't care about cookies" Firefox addon. Like another user here, I'm posting for posterity.
This could also be a simple syntax error. I had a syntax error which threw on FF but not Chrome as follows:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js">
defer
</script>
I've just run into this issue while building Facebook Login into my ASP.NET project.
It turned out to be an extension called Facebook Container, which blocks the Facebook SDK script unless you add an exception for the site in question.
Once I added the exception it all worked fine.
Ran into the same problem today. It turned out that there was no storage space left on the VM the site was running on and therefore requests weren't completely handled anymore.
After cleaning things up (notably Docker-related stuff), everything works fine again.
For me it wasn't AdBlock, but actually a wrong relative path. Wrong error message I guess. I was able to see this in the server logs.
For me it was NoScript extension which was installed by default by my company. I configured localhost to be safe, then it worked.
For me (Next.js project static export) it was due to cache. I did a hard refresh Ctrl + F5 and everything started working fine.
I was hoping to do some experimentation with the chrome.downloads api. I downloaded the dev and canary versions of Chrome and created a new extension with the downloads permission, as well as <all_urls>.
When I load the extension, the "permissions" link shows I have permission to "Download files" so the permission is being loaded successfully.
When I inspect the "chrome" object in the debugger, chrome.downloads is set to undefined. If I go to use the object it causes the extension to unload. It also causes an empty notification to appear in the corner of the screen, but as it doesn't have any content I can't tell if this is meant to be a message informing me that I've not done something I need to.
In addition I downloaded the example extension, Downloads Overwrite Existing Files, which also fails to run on either dev or canary.
Does anyone know how to get this working? As far as I can tell I have done everything that is required.
You are probably seeing two unrelated bugs in action. The empty notification is https://code.google.com/p/chromium/issues/detail?id=181191, which is preventing you from seeing the contents: "Downloads Overwrite Existing Files has crashed. Click this balloon to reload the extension." This bug cropped up very recently, and we're looking at it now.
The other bug, as you've probably guessed, is that crash. I just filed it here: https://code.google.com/p/chromium/issues/detail?id=197926.
Sorry for the trouble. This is part of the fun of running on some of the more "exciting" channels. This is a pretty lame answer to your question because it doesn't get you unblocked, but it is a correct explanation of what's going on.
I'm working on developing a site on my local machine (Windows 7 Ultimate x64) using WAMP, running APACHE v2.2.22, PHP 5.3.13, and MySQL v5.5.24. I'm developing using Chrome v 22.0.1229.94. I've got quite a bit of javascript in the site, however, and Chrome is relentlessly blocking javascript from running on the page.
Clicking on the little 'blocked javascript on this page' icon in the address bar includes the dropdown that has "Always allow Javascript on Localhost" checked off, and I also have a JavaScript exception in Chrome's settings explicitly saying to always allow JavaScript on 'http://localhost'.
Cookies are being allowed, "Allow all sites to run JavaScript" is checked off, and I have no idea as to why Chrome is not allowing the JavaScript to run.
Overall, it's not imperative to the project that I figure out a fix as both IE9 and Firefox 16.1 are allowing JavaScript and I can utilize them. I am simply curious if there's anything I can do to fix this in Chrome, as I would like to continue developing in Chrome.
If you notice that JavaScript is only blocked when the console is open (as some are saying), chances are that you disabled JavaScript in the console settings.
Open the console.
Click the vertical ellipsis icon (or the gear icon on older versions) in the upper right and go to settings.
See if the "Disable JavaScript" checkbox is checked.
I have the same issue, but only when the console is open. When the console is closed, JavaScript loads fine on localhost. Makes it hard to debug things though....
I got around it by opening localhost in an incognito window.
You can give your local server a domain name, may be that would help.
Open C:\Windows\System32\drivers\etc\hosts in notepad
Edit that file add a new line at the end
127.0.0.1 mydomain.com
Save, now goto chrome and type in http://mydomain.com/ this should point to your local server.
Since you nolonger run on "localhost" may be chrome will let you pass.
Let's me know if that works. Good luck!
I'm having a really annoying problem with debugging javascript with VS2008.
If I simply press F5 (or choose 'start Debugging' from the Debug menu), the iexplore process is attached, but no breakpoints break in the scripts. The Script Documents tree doesn't even appear in the solution explorer.
I already know:
I can set a breakpoint in Javascript just fine. It does NOT show the "This point will not be hit" message.
Calling the debugger through using the 'debugger' keyword works fine, but attaching to the iexplore process doesn't since it gives a "process already attached to a debugger" message.
Using the manual 'Attach to process...' works just fine. The Script Documents appears as well.
The project has recently been converted to a Web Application from a WebSite.
I already tried:
Clearing the IE cache.
Shutting down VS2008, Stopping the IIS and deleting the temporary asp.NET files restarting both IIS and VS2008 afterwards.
Setting IE7 as the default browser both for windows and for VS2008.
Resetting my user settings for VS2008.
Checking that IE script debugging is enabled.
Nothing has worked so far. While Attaching to process isn't too taxing, it is very annoying when I'm used to just hitting F5.
If anyone can think of a solution, please please please (I'm begging here!) let me know!
Is silverlight debugging enabled on the website project properties? This will disable Javascript debugging.
