Images not showing up in Canvas after last Firefox update.

I am a university professor. All of my classes use Canvas software. After last week's Firefox update, none of the embedded figures on my course pages appear - only their file name. They are showing up just fine in Chrome, so I know that the problem is somehow connected to Firefox. They also disappeared immediately after the last update.

My students and I need to be able to see the images...and I don't want to uses Chrome. I would like to know how to either return Firefox to its previous version or have the new version somehow corrected so that it gets along with Canvas.

Thank you.

Is this different from Blackboard? Several users have reported some content failing to load in Blackboard.

Here are some standard things to check:

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

(A) The shield icon toward the left end of the address bar usually turns a bit purplish when content is blocked. Click the icon to learn more or make an exception. See: Enhanced Tracking Protection in Firefox for desktop.

(B) Extensions such as Adblock Plus, Blur, Disconnect, DuckDuckGo Privacy Essentials, Ghostery, NoScript, Privacy Badger, uBlock Origin or uMatrix usually provide a toolbar button 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 sometimes 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 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. A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

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

Any improvement?

Thank you very much. It turned out that the issue was Privacy Badger was blocking the images. I really appreciate your response!
