Hi Moxhelp, the whole image blocking feature is being phased out and handed over to add-ons. We are in transition.

When you are on a page with blocked images, you can use the Page Info dialog to check whether that is a stored preference for the source site. Here's how:

Either:

• right-click a blank area of the page and choose View Page Info
• (menu bar) Tools menu > Page Info

Along the top, click the Media icon.

In the list box full of image URLs, click the first one and glance toward the preview area. Just above that is a checkbox to block images from the source site. If it's blocked, un-check it.

Use the down arrow to scan though the list and clear any blocked sources.

Any improvement?

If that didn't make any difference consider whether it could be Content Blocking/Tracking Protection, or one of your add-ons.

Double-check content blockers: Firefox's Content Blocking feature and extensions that counter ads and tracking may break websites that embed third party content (meaning, from a secondary server).

(A) Do you see a shield icon toward the left end of the address bar, near the lock icon? More info on managing the Tracking Protection feature in this article: Enhanced Tracking Protection in Firefox for desktop.

(B) Extensions such as Adblock Plus, Blur, Disconnect, Ghostery, NoScript, Privacy Badger, uBlock Origin or uMatrix should provide toolbar buttons to manage blocked content in a page. There may or may not be a number on the icon indicating the number of blocked items; you may need to click the button to see what's going on and test whether you need to make an exception for this site.

Testing in Firefox's Safe Mode: In its Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is not running: Hold down the Shift key when starting Firefox. (On Mac, hold down the option/alt key instead of the Shift key.)

If Firefox is running: You can restart Firefox in Safe Mode using either:

• "3-bar" menu button > "?" Help > Restart with Add-ons Disabled
• (menu bar) Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement?

Thanks for your reply. "Just above that is a checkbox to block images from the source site. If it's blocked, un-check it." - none of these are checked, for any graphics for any site

I will have to check out the possibility of add-ons causing trouble.

But that still doesn't answer why I have no option in the Preferences for "Load Images". or is that what you meant by "the whole image blocking feature is being phased out and handed over to add-ons. We are in transition."

Has "Load Images" already been pulled out of Preferences?

Thanks

Yes, "Load Images" is gone from the Permissions panel in Firefox 71 (as you noticed).

You can check in the Web Console for possible messages about blocked content.

• "3-bar" menu button or Tools -> Web Developer
• https://developer.mozilla.org/en-US/Tools/Web_Console

I started Mozilla in Safe Mode and this fixed the problem. I them started it in normal mode and disabled all of my add-ons one-by-one. Even after all were disabled however, the problem is still there. Does this suggest that it's not an add-on causing the problem?

I then followed your suggestion Cor-el and checked the Web Console. For all the blocked graphics, there's a line stating "The resource at .... was blocked because content blocking is enabled." Most of these are from "https://gallery.mailchimp.com/", or "https://cdn-images.mailchimp.com/". There are also some blocked from "....list-manage.com...."

What's the best way to deal with this? I'd prefer to not turn off tracking protection for all of outlook.com (interestingly, when I click on the shield icon next to the address, there is now an option to turn off "enhanced tracking protection" for this site. This wasn't there when I first posted this problem and I'm still running the same version of Mozilla, v71.0).

Is there a way to 'white-list' mailchimp, or the specific senders that are using mailchip, or something else, to prevent the graphics from being blocked for only the problem emails? Thanks!
