In Thunderbird version 12.01, is there a way to disable the remote content warning that appears in situations such as: when an HTML email wants to load images hosted online?

I expected that the Security tab in Preferences would have an two options: Don't load remote content and Don't warn when an email requests remote content. Not finding this, I went to about:config (config editor) looking for the options. I found

mailnews.message_display.disable_remote_image => true

but settings this to false automatically loads the remote content, which is not the intended outcome.

Is there a way to suppress the prompt to "Show Remote Content" without loading the remote content?

(just as an addendum, I don't want to add contacts to my contact list)

There is a hidden switch for this:

In about:config (Preferences -> Advanced -> Config Editor) look for:

  • Thunderbird version 31 once again has broken the setting, so now this trick is obsolete... – Alexander Shcheblikin Aug 19 '14 at 11:22
  • Yet another solution is to select Simple HTML in the View message as menu. superuser.com/a/173612/175541 – Alexander Shcheblikin Sep 4 '14 at 11:38
  • No, it does work. Thunderbird 38.5.1 on Mac OS X 10.11. No remote content. No yellow stripe. So much better.... – Ray Kiddy Jan 12 '16 at 21:28

You won't get that warning if you use the Allow HTML Temp add-on and set it to view emails in Simple HTML or Plain Text.
