1538309 - Images in blog broadcast fail to load in firefox

Status: RESOLVED INVALID

(Core :: Layout: Images, Video, and HTML Frames, defect)

Description

[Jason Ross]

Attachment: screenshot-bug.jpg

User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:66.0) Gecko/20100101 Firefox/66.0

Steps to reproduce:

Set up email broadcast of wordpress site's RSS feed in Mailchimp in mid-late 2018, feed was set to broadcast titles, feature images and teaser of articles posted within the last week. At this point the code was working properly and all the newsletter boradcasts were working as expected.

Actual results:

The code was working properly across all browsers and email viewing platforms until somewhere between March 7 and March 14. No changes were made to the RSS code in Mailchimp, yet now all newsletter broadcasts display only the alt text for the feed images and using the inspect tool brings up an error message saying the image cannot be loaded. I can link through to the image file and confirm it is being correctly linked to by the generated html code.

Testing in Aweber using Firefox produced the same results, alt tags only display. 1 week of troubleshooting with the developer of an RSS plugin failed to resolve the issue but did rule out WordPress, Mailchimp, or any wordpress theme or plugins as being the cause.

Testing in Chrome, the images display normally in all tests.

Expected results:

The html code MailChimp and Aweber generated appears to be properly configured and pointing to the images and the images are in place. The newsletter emails should load and display the images in accordance with the generated html.

Hi, This is a bit to technical for me to reproduce, Can you provide the RSS link or a simple Use Case that might help us reproduce this issue ?

You can also try reproducing this issue in Safe Mode and see if it still occurs, you have the steps here: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

Or maybe in our latest Nightly since it might have been fixed already, you can find the build here: https://nightly.mozilla.org/

In the mean time I'll set the component to Core Layout: Images, Videos and HTML frames, but I'm not sure if it's the correct one , Please feel free to change the component if there is a better suited for it.

Please post a URL that reproduces the issue, I'm happy to take a look :)

You can reproduce by creating a free mailchimp account, and set up a blog/newsletter broadcast. The RSS feed I'm having this issue with is https://www.theafronews.com/feed/

To see the issue, have that mailchimp campaign send out a test email and you'll see no images in the email, just the alt text. If you check the feed directly using an rss reader, you'll note that the images are present, and if you run the test using Chrome, you'll again see the images are present.

I think this might just be content-blocking...?

I followed the suggested steps from comment 3 and 4, and then clicked "View Email" next to my testing mailchimp campgaign, and if I have Strict Content Blocking enabled (or if I view the email in a Private Browsing window), then indeed I see three broken image icons for Social Widgets at the bottom of the email. And I also see a shield in my URL bar indicating that Firefox blocked some stuff -- if I click that shield and choose "Turn off blocking for this site", then the images load just fine.

Jason, does this match your experience?

Here's the "View Email" link, for my testing mailchimp campaign -- it seems to be publicly viewable:

Attachment: screencast of "strict" content being the thing that causes images to be blocked

Here's a screencast of what I see with my test campaign page:

• starting with default configuration [where images are loaded successfully]
• ...and then switching to strict content blocking where the images end up blocked
• ...until I disable content blocking for this site using the shield in the URL bar.

Jason, does this match your experience?

BTW if you're seeing something substantially different, then it'd be quite helpful if you could provide either/both of the following:

(1) the URL of an affected email (for the "View this email in your browser" version of one of your emails, assuming it's affected -- like the one that I provided in comment 6 for example).

(2) the URLs of some of the images that are blocked.

Comment 9

[Jason Ross]

It wasn't the exact thing you mentioned, but it was something similar. I'm using Privacy Badger which is a privacy/security plugin which does a similar thing to your shield icon. It was blocking the images and when I disabled it both for my email inbox and in mailchimp, that fixed the problem.

I hadn't expected PB to be a problem as it never used to be. Thanks for pointing me in the right direction.

Great! Things seem to be working as-expected then. :) I'll close this out as INVALID since there's no Firefox bug here.
