Email content blocked with no option to restore

Hi,

For a number of months now my Thunderbird installation has been playing up. I have used Thunderbird without issue for several years, however now, whenever it downloads emails, any content (other than simple text) is automatically deleted out of it. For a split second, as the email is being retrieved, I can see all (graphical) content, however less than a second later, it all disappears, and an empty box where the image/link used to be remains in its place. I have read about Thunderbirds "protect your privacy" and content security, but contrary to the instructions therein, there is no means for me to 1. Re-enable content (there is no blue preferences bar present at any time in the email application) 2. Such preferences anywhere in the settings that I can find.

This is extremely frustrating. I left it for a while hoping that an eventual Thunderbird software update would resolve the issue, but it hasn't. how do I go about restoring the content of these emails? Note I realize that security is important, however we are talking about known good companies that I regularly deal with, and their content is stripped out with no means for me to disable or opt out of this infuriating bug/feature.

I am running Ubuntu 18.04 and the latest version of Thunderbird (everything on my machine is kept 100% up to date)

Thank you

Remote content won't be displayed if View/Message Body As is anything other than Original HTML. Is that a factor?

I wouldn't know. How would I tell? It (Thunderbird) never used to do this, but now it happens to the vast majority of emails that I receive from legitimate sources. I also find it interesting that it is definitely downloading all content (as it is briefly visible in the email when messages are downloaded, just before the content is deleted).

How do I disable this "feature"?

You would click the 3-bar AppMenu icon, View, Message Body As.

Thanks, I found that. Yes, it is set/checked for Original HTML. So it's not that causing my email content to be auto-deleted.

Are the remote images visible when you view messages through webmail? If they aren't, the blocking occurs at the mail provider's end, before the mail is downloaded to TB.

Images do appear to be blocked when i use my web mail option, however it gives me the option to still download remote images. When I click yes, my remote images are downloaded in the web email for Hostpapa (my service provider for email).

However I have listed websites in the whitelist or exceptions under email preferences for Thunderbird, and they are still blocked. Also, at no point does Thunderbird ask me if i want to download images anyway. Furthermore, as I've pointed out earlier, if I click away from the email (eg into another email) and then back, the preview pane briefly shows the images all downloaded, just before they magically disappear about half a second later. IE whatever privacy "protection" is being made available by suppressing images is moot, as the images have obviously already been downloaded from their respective sources. Unfortunately, given the brief time involved, this is not easy for me to demonstrate to you, but I have done it many times with some emails to prove this to be the case. Each time I go back and forth, I see the images appear in the email, and then they are deleted or disappear.

It is definitely remote content, at l can now confirm this, as they are the same images that are blocked when I view the email in my webmail (except of course I can restore them in web mail).

ah, I found a way to record the video (using OBS in my Ubuntu machine) and then take a couple of screenshots to demonstrate what I am seeing. See the associated images, with the first one being the email in the preview pane, as I click on the email. About a second later, the image disappears, and I am left with what you see in the second image. The cycle can be repeated as many times as I want, simply by clicking on any other email, and then clicking back on this respective email.

I would suggest you permanently whitelist the senders in webmail, maybe by adding them to the webmail contacts or clicking 'always allow remote content from ....', and then re-downloading the folder in TB by right-click, Properties, Repair Folder. If you have the exceptions in Options/Privacy and view is Original HTML, the images should display.

Well I have had a look at my webmail client (Hostpapa, CPanel) and there doesn't appear to be any means of white or blacklisting the downloading of images etc. I do have options to white/blacklist emails from certain people/companies etc. but that is only to mark as spam (in which case it wouldn't end up in my inbox at all, so this is not my problem).

Finally, if you read my earlier responses, along with screenshots, you will see that Thunderbird IS downloading the images, BUT then immediately blanks or deletes them out! I can repeat this over and over again, and every time, I will see the image briefly in the email, before it disappears. I am doing this not even by downloading emails, but simply by clicking on any other email, and then clicking back on the email in question. As a means of preventing spam etc. it isn't logical for Thunderbird to first download the images, and then delete them every time.

Please take a look at my earlier response, along with the two images to see what I mean, thank you.

To be quite clear THUNDERBIRD HAS ALREADY DOWNLOADED THE IMAGES, BUT THEN CHOOSES TO DELETE/BLANK THEM AFTERWARDS.

Apologies, I ended up quoting as opposed to editing my last message, so it's been repeated about 5 times. then again, I am getting extremely frustrated with having to repeat over and over again the fact that thunderbird has already downloaded the images, so this is clearly NOT an issue of images being blocked by webmail.
