To allow a specific email address to always show remote content.

select the email so you can read it in the Message Pane. You will see 'To protect your privacy; Thunderbird has blocked remote content in this message'. Click on 'Options' button. Select: 'allow remote content for email address'

Then further emails from that email address will show remote content.

A list of all email addresses that have been allowed can be located here:

Edit > Preferences > Privacy Mail content: click on 'Exceptions' button.

There is also the option of always allowing display of remote content no matter what the email address. select to 'Allow remote content in messages' However, before you select that option you should read the information at the link: https://support.mozilla.org/en-US/kb/remote-content-in-messages

When finished click on OK.

I don't want everything to open a browser, just those things I select ON THE FLY, not preselected. You reference the following:

" Display remote content for a particular message

Remote content blocking options

From the notification bar you can choose to:

   Show remote content in this message to show remote content just for this particular message OR
   Edit remote content preferences... to Display remote content by default (see next section).
   Allow remote content for... to show the remote content for all messages from this sender. 

Allow remote content for... adds the sender email address or sites (currently blocked in the message) to the remote content whitelist.

What I'm complaining about is that in the one computer I DON"T HAVE THAT NOTIFICATION BAR that apparently is supposed to pop up when a graphic is present. How do I get it?

I'm puzzled as to why "Show remote content" should fire up your web browser. My experience and expectation is to see the previously-disabled content in the email message itself.

When you don't get the prompt to decide what to do with remote content, could the sender already be in your Address Book? If the star by the sender's name is yellow, then the answer is yes. Click this star to edit the address book entry, or if the star is white/clear, clicking it allows you to add the sender to your address book.

Contact entries in the Address Book have a "Permit remote content" checkbox that might affect the display of the content prompt.

I don't know why that's the way it works, it's your code, not mine. I just want the same capability on my desktop computer as I have on my laptop, and I haven't done anything special to get things the way they are. I just downloaded Thunderbird from the repos in PCLinuxOS via the file manager in that system, Synaptic, and installed them. They have the same Mozilla version number, why aren't they the same? And it used to be--maybe six months ago, at least a year ago, that all versions of Thunderbird would work that way, with a preferences balloon that let you open a graphic email in the browser, i.e. Firefox.

I have found that sometimes you get that option to open in a browser if the sender incorporated it in their email. For example, I have an email from a magazine company, they have include a 'see this email in your browser' link. I have another email from a gardening supplier withe a 'view this email 'online' link. These links are located top right in email, so appear below the 'show remote content' option.

If the sender incorporated a link in a graphic image to a webage then that will open in a browser.

But I've never been able to open an email in a browser from the 'show remote control' option as that option only allows remote images to be displayed.

In TB version 31.1.2

Edit > Preferences > Privacy Mail content: click on 'Exceptions' button.

If the email address has already been selected to allow remote content then it will be listed here. You can remove it if desired.

I don't understand why you people who have made this product don't know how it works. Even in your email, there came up a preferences box on a new ribbon under the "from/subject/to ribbon. I DO NOT want to go to "Privacy" and allow every graphic email to be displayed in the browser, I want ONLY THE EMAILS THAT I SELECT WHEN THEY COME IN to display on the browser. It works on this Dell laptop. It works on a desktop with a Gigabyte mobo, but it does NOT work on a desktop with a Foxconn mobo. Is there any way I can send y0u a picture of the screen with this system working, just to prove I'm not crazy?

For the most part, those who write to this forum are just fellow users, giving freely of their own time and sharing their knowledge and experience.

Right below the box you type into, there is the phrase "Add images" and a button to launch a file browser.
