https domain, try download JS from no-secure http - javascript

I'm have domain on HTTPS, with JS <script src="http://example.com/some.js?key=cf04b31a52ed4c"> and this script doesn't load. On other domain without SSL, all OK. This problem can resolve if I'm change protocol example.com to HTTPS too or no?

I would try to use:
<script src="///example.com/some.js?key=cf04b31a52ed4c">
just in case they provide it also using HTTPS, or check the Content Security Policy. On recent Chrome and Firefox the developer console should give you a more informed error on whats wrong.

The error you're getting is confirming your suspicions -- your browser security settings are set to not load unsecured content over a secured connection. Presuming some of your users may have similar settings, it'd be best to serve all of your content over a secured connection as well.

All CDN's blocked by Content Security Policy

I just wanted to make a simple website with Node.js, but I can't manage to get the CDN of CSS and JS files from Bootstrap without being blocked by Content Security Policy.
Here's what happens:
CASE 1 (works): When I just move my HTML file in the browser (so C://... .html) it works and gets all CDN's
CASE 2 (doesn't work): When I start my server (using express) in Node.js and then go to localhost:4000, it doesn't get the CDN's due to Content Security Policy (I can see it in console as it says it's being blocked by it)
I tried to put in the meta tag with the CDN's in it from here: Content Security Policy: The page's settings blocked the loading of a resource, but it didn't work and I even got more errors.
How do I fix this? I can't find any solution.
CASE 1 (works): When I just move my HTML file in the browser (so C://... .html) it works and gets all cdn's
When you web page works from C://... .html it's no Content Security Policy (CSP) published therefore nothing is blocked.
CASE 2 (doesn't work): When I start my server (using express) in Node.js and then go to localhost:4000 it doesn't get the CDN's due to Content Security Policy (I can see it in console as it says its being blocked by it)
When you web page works from localhost:4000 the server publishes a default CSP. NodeJS has in dependencies a Helmet middleware which publishes this default CSP header.
You can disable a middleware:
// This disables the `contentSecurityPolicy` middleware but keeps the rest.
app.use(
helmet({
contentSecurityPolicy: false,
})
);
or configure it to allow external CDNs, see details in helmet.contentSecurityPolicy(options) section.
Note: next time please add console messages into a question, they can be very helpful in case of CSP.
Content Security Policy works the other way around. The CDN needs to give access to your url to use their resource, not the other way around. They will have to add a header with access-control-allow-origin and then set the value of * which means anyone can use their resource files or specifically your domain url.
So most likely you have a typo in your url and that domain doesn't allow localhost to fetch their js files.

Loading script from HTTP is automatically converted to HTTPS for some users

I am trying to load socket.io using the following code:
<script src="http://cdn.socket.io/socket.io-1.4.5.js"></script>
However some users have reported the following error to me:
Failed to load https://cdn.socket.io/socket.io-1.4.5.js ERR_SSL_PROTOCOL_ERROR
Is this an automatic security setting on modern browsers? And if so can it be disabled?
The problem is not your fault!
Accessing that link in my browser fails as well, and inspecting the unsuccessful request shows that the following header was set:
Upgrade-Insecure-Requests: 1
This tells the browser to "upgrade" all http:// URLs to https://, which seems to mirror the error your users are reporting.
ERR_SSL_PROTOCOL_ERROR indicates that the SSL certificate for https://cdn.socket.io/ is incorrectly configured and thus the browser (rightly) assumes the worst, and chooses not to trust data served from that domain over the secure protocol. When the domain is configured to "upgrade" insecure requests to secure ones, and secure requests are rejected by the browser, it becomes clear why there is no way to access the content correctly at either URL.
I would contact the administrators of the website and inform them of the problem, or just simply switch to another CDN like Chris Chen suggested:
<script src="https://cdnjs.cloudflare.com/ajax/libs/socket.io/1.4.5/socket.io.min.js"></‌​script>
Sounds like the users who are experiencing that error are hitting the https version of your page. Best way to deal with this issue is by changing your code to:
<script src="//cdn.socket.io/socket.io-1.4.5.js"></script>
Or
<script src="https://cdn.socket.io/socket.io-1.4.5.js"></script>
The former is preferable (because it is faster for http users) unless you are working with an .html or .htm page and want to open it without a web server.
The link is not working at all from anywhere. Is it a private link that require certification?
If you just want socket.io.js, use link from https://cdnjs.com/libraries/socket.io

How to solve "Mixed content"-issue on Google-Chrome Console

I have an issue where the following is being displayed:
Mixed Content: The page at 'https://www.feelhome.se/produkt/fighting-elephants/' was loaded over HTTPS, but requested an insecure stylesheet 'http://fonts.googleapis.com/css?family=Source+Sans+Pro:400,700,600italic,600,400italic,300italic,300,200italic,200'. This request has been blocked; the content must be served over HTTPS.
Does anyone have an idea on how I can solve this so it won't appear?
The problems is that the you are loading the fonts using http instead of https if you change the font url to use https you'll be ok.
So you need
https://fonts.googleapis.com/css?family=Source+Sans+Pro:400,700,600italic,600,400italic,300italic,300,200italic,200
instead of
http://fonts.googleapis.com/css?family=Source+Sans+Pro:400,700,600italic,600,400italic,300italic,300,200italic,200
The fonts seam to be loaded from the template.css and bootstrap.css files. Have a look at the attached image.
A secure page only has https resources (like stylesheets or images). When one or more resources are loaded via http, the security might be comprimised. That is the warning you're getting, you have some http resourcce on a https page.
Some have suggested placing https://example.com in front of everything, I'm going to suggest something else: //example.com, note the lack of https and http. The browser will now add https automatically.
The benefit here is that when you have to switch between the two, you're done with the minimal amount of work. Say you have a site which is allready build and running, and after a time decides to go https... All you have to do is change your htaccess and done, all your resources are prepared.
The content you have could be insecure, so you need to load it with
https instead of http.

AJAX Blocked from chrome extension content_script

i'm writing a chrome extension that use a content_script.
the content script use XMLHttpRequest to send information about the page to my server, and base on that information the server respond with somethings that has to be done.
everything works well on http pages, but fail on http*s*.
The error i get is:
[blocked] The page at '==https page==' was loaded over HTTPS, but ran insecure content from '===myserver - http===': this content should also be loaded over HTTPS.
If i will use https on my server will it work? even though it's a different domain? is there any way to do it without using ssl on my server?
Thanks.
Yes, you can only call https content from an https page. See these for help on mixed content issue :
https://support.google.com/chrome/answer/1342714?hl=en
http://kb.iu.edu/data/bdny.html
You can test your extension with mixed content by enabling it explicitly as instructed at:
http://wiki.sln.suny.edu/display/SLNKB/Enabling+mixed+content+in+Google+Chrome
If you enable SSL/https on your web-server this will solve the issue for your users also. A cheaper and easier way to enable SSL on your server almost instantly would be to use Cloudflare.

bookmarklet on https page

I'm trying to make a bookmarklet to use on youtube and other video sites in order to easily get information from the video and store it elsewhere.
From today, apparently I can't do that anymore since youtube force itself on a https connection and from what I've read on chrome's console window, the bookmarklet doesn't run on a https page. Is there a workaround?
Here is the edited code:
javascript:(function(){var jsCode=document.createElement('script');jsCode.setAttribute('src','http://[mysite]/b/enter.php?i=userid&r='+Math.random());document.body.appendChild(jsCode);}());
Google Chrome (and possibly other browsers?) blocks HTTP resources from being accessed from an HTTPS document. This is to prevent "mixed content" attacks, in which insecure HTTP scripts could be intercepted by an attacker in transit over the network and altered to perform any kind of malicious activity (e.g., leak cookies or sensitive page information to a third party). Such a violation would undo any protection granted by HTTPS.
Chrome used to provide a prominent warning that an insecure resource was blocked, but now it no longer does so, and all insecure loads silently fail. The only solution available to you at this time is to use HTTPS yourself when you serve the script.
In Firefox, if you want to run a bookmarklet that references http on an https page, the way to get around this is to temporarily disable security.mixed_content.block_active_content. There are two ways to do this.
go to about:config in a new tab, search for security.mixed_content.block_active_content and then toggle the value to false. Run your bookmarklet and then toggle it back to true (since you probably want it turned on most of the time).
use an add-on / extension to toggle the block. A quick search turned up Toggle Mixed Active Content, and a quick test seemed to work well. There may be others.
Have fun and be careful. Here be dragons!
the bookmarklet doesn't run on a https page
Why not?
Try changing to a HTTPS domain yourself. Usually HTTP content is blocked when you're on a HTTPS domain.
I have created a work-around "fix" for this issue using a Greasemonkey userscript. You can now have bookmarklets on all CSP and https:// sites, plus have your bookmarklets in a nice, easily-editable library file instead of being individually squished into a bookmark.
