Firefox Mixed Content Blocker - security

On my site served over https a user may enter a URL and preview their entered URL in an embedded iframe.
This iframe is getting blocked by Firefox 23's mixed content blocker by default. I'm wondering if anyone knows of a workaround.

You could try using Snapito! (http://snapito.com).
They have an API that works over https, so if you used their preview you would cease getting mixed content.

Image URL being redirected to other web site

I am trying to use an image from an existing website in my html page. The issue is that the image is not getting resolved correctly, Even when I hit the image URL directly on browser, its getting redirected to some other site. I have tried on all browsers but no luck.
I have heard about restricting resource using hot linking but in this case not sure whats happening. Any pointers/suggestions please.
Eg - I want to use image(http://www.acsisair.com.au/wp-content/themes/acsis-air/images/logo.png) but when hitting this URL after clearing browser cache, its being redirected to other website (http://www.nine.com.au)
It's very, very likely a form of hotlinking protection: if you change the URL subtly to make it clearly incorrect, you get a 404 page.
That means when you enter an URL to a resource that exists, you're given a header redirect. That's not an accident.
There's likely nothing you can (or should) do to circumvent this.
Use images you can host on your own site.

Do you want to view only the webpage content that was delivered securely? secury waring in ie, how can i fix though programing

Ie showing following issue, how can i fix this though programing? Sorry for browser security fix
"Do you want to view only the webpage content that was delivered securely?
This webpage contains content that will not be delivered using a secure HTTPS connection, which could compromise the securty of the enture webpages."
That's a warning that you're serving some content via HTTPS and some via HTTP. To avoid that warning, ensure that everything is being served via HTTPS.
Unfortunately without more details that's all the advice I can offer.

How to identify mixed content in https website

I've inherited an ASP.NET web site that has an SSL certificate bought via GoDaddy.
The problem is that the certificate seems to be invalid because of some "mixed content/resources" (I think that's how its called) coming from http sites.
Chrome is showing the red cross over the lock next to https, meaning it's unsecured. The popups says the following:
Click in "What do these mean?" goes here which says:
The [crossed-lock] icon appears when
Google Chrome detects high-risk mixed
content, such as JavaScript, on the
page or when the site presents an
invalid certificate.
The certificate is correct and valid because I tried creating a blank "Hi world" .aspx page and it's showing the green lock with no problems.
Reading a little bit, I found that I should only include images and javascript coming from https sites. The only thing it had coming from http was the addthis widget, but they support https, so I changed to https, but it's still saying that is unsecured.
I've searched for anything else coming from http in the source, but didn't find anything.
Is there some way (site, chrome extension, firefox extension, whatever) that will show exactly which are the resources that are "unsecured"?
I've never dealt with SSL/HTTPS certificates, but I need to fix this issue asap.
Check your site in http://www.whynopadlock.com, which will give you a list of url which is not consider as secure by your browser.
Check the chrome console
You will get it like this,
The page at https://xys displayed insecure content from http://asdasda.png.
Make it http site to https then it will work.
I've found the problem using the Chrome Developer Tools. It was a js that's embedding a flash from an 3rd party site which it's using http.
Are you on Windows? Download and run Fiddler while browsing the site, and watch for HTTP connections.
Mixed content means contents of a web page are mixed with HTTP and HTTPS links.
These links include your JS, CSS, Image, Video, Audio, Iframes etc.
If your website is enabled for HTTPS (SSL certificate has installed), make sure you serve only HTTPS contents throughout your web page.

Website not available unless www is in front of the url in Chrome browser are there any tricks to fix this?

My website is accessible without www in the front of it in Firefox and Safari however for some reason it is not in Chrome. Is there anything that I need to change on my website host or in the html to make it accessible?
If your website is not already set up to do so, you'll need to update your web host to respect requests for http://your-website.com as well as http://www.your-website.com.
Firefox (and apparently Safari) will make a second request to a URL using or removing the www. in front of it if they receive a 404 error before displaying any resulting errors to the user. (And if the alternate URL works they will display the results of the second request and silently drop the results of the first [the 404 error].) Most, if not all other browsers will just display the first 404 error page.
What web server are you running on?

Why is Chrome reporting a secure / non secure warning when no other browsers aren't?

When I go to our web site through HTTPS mode, Chome is reporting an error saying that the page contains secure and not secure items. However, I used Firebug, Fiddler, and HttpDebuggerPro, all which are telling me that everything is going through HTTPS. Is this a bug in Chrome?
Sorry but I'm unable to give out the actual URL.
A bit late to the party here but I've been having issues recently and once I had found a http resource and changed it was still getting the red padlock symbol. When I closed the tab and opened a new one it changed to a green padlock so I guess Chrome caches this information for the lifetime of the tab
Current versions of Chrome will show the mixed content's URL in the error console. Hit CTRL+Shift+J and you'll see text like:
"The page at https://www.fiddler2.com/test/securepageinsecureimage.htm contains insecure content from http://www.fiddler2.com/Eric/images/me.jpg."
I was having the same issue: Chromium showing the non-secure static files, but when everything was http://.
Just closing the current tab and re-opening the page in another new tab worked, so I think this is a Chromium/Chrome bug.
Cheers,
Diogo
Using Chrome, if you open up the Developer Tools (View > Developer > Developer Tools) and bring up the Console and choose to filter to warnings, you'll see a list of offending URLs.
You'll see something like the following if you do have insecure content
The page at https://mysite/ displayed insecure content from http://insecureurl.
For the best experience in finding the culprit, you'll want to start your investigation in a new tab.
It is possible that a non-secure URL is referenced but not accessed (e.g. the codebase for a Flash <object>).
I ran into this problem when Jquery was being executing a a few seconds after page load which added a class containing a non-secure image background. Chrome must continually to check for any non-secure resources to be loaded.
See the code example below. If you had code like this, the green padlock is shown in Chrome for about 5 seconds until the deferred class is applied to the div.
setTimeout(function() {
$("#some-div").addClass("deferred")
}, 5000);
.deferred
{
background: url(http://not-secure.com/not-secure.jpg"
}
Check the source of the page for any external objects (scripts, stylesheets, images, objects) linked using http://... rather than https://... or a relative path. Change the links to use relative paths, or absolute paths without protocol, i.e. href="/path/to/file".
If all that if fine, it could be something included from Javascript. For example, the Google Analytics code uses document.write to add a new script to the page, but it has code to check for HTTPS in case the calling page is secure:
<script type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
On the release of Chrome version 53 on Windows, Google has changed the trust indications to initiate the circle-i. Afterward, Google has announced a new warning message will be issued when a website is not using HTTPS.
From 2017 January Start, Popular web browser Chrome will begin
labeling HTTP sites as “Not Secure” [Which transmit passwords / ask
for credit card details]
If all your resources are indeed secure, then it is a bug. http://code.google.com/p/chromium/issues/detail?id=72015 . Luckily it was fixed.
