My Thunderbird e-mail suddenly appears different.

There is now an Options box for every e-mail with remote content. So I have to click on the Options box each time to see more detail. Only had to do this occasionally before. Also, now in composing an e-mail, the area below TO: (eg; Subject) is now blued out unless I click on an area. Did my Thunderbird get upgraded somehow or did my wife in accessing e-mail inadvertently click on something that changed the appearance and functionality of my e-mail system?

You know there is a whole article on this change https://support.mozilla.org/en-US/kb/remote-content-in-messages

But to summarise the history.

Thunderbird previously used the address book as a white-list for remote images. This is no longer the case as approval of images per sender is really not logical. Approval of images per source is. So the new method has a new whitelist (so you have to start again on that really), and options to white list images by source. The domains mentioned in the list are the ones images in the mail come from. The net result is those that hijack an friends email account to send spam will not get their images into your mail box unless you specifically allow them.

One thing to keep in mind is that images do not have to be remote, so these controls only cover remote images. Images that are sent as a part of the email will not be blocked ever.

I changed my theme in windows and that made TB look blue. Remote contents could carry a virusthreat and could reveal your identity, so be happy spammail pop up their remote contents without you wanting it. But this isn't a new thing, is it?

I do not recall changing anything in Windows. Also, I used to get the remote contents request on occasion but now it is on everything - such as every time that I have indicated something as not spam (eg- Groupon), the Options box appears each time and I have to click on it to show the remote content. That did not happen before this change this week.

On settings / security there is a checkbox "allow remote contents".

Actually - I found it under Tools, then Options. It was unchecked which I believe it always has been. So I am puzzled as to why the sudden change in appearance. By the way, my TB is version 31.3.0.

So you leave "show remote content" unchecked?
