In order to protect myself from getting trojans and other stuff, I have changed Thunderbird’s options to only display emails in a simplified HTML format. But this format takes away pretty much of the advantages HTML emails have to offer (for example, writing justified text).
I am using NoScript and do not click on links from spam emails.
Fallacy 1: “If I just look at an email but do not open an attachment, nothing can happen.”
Unfortunately, this is not true. Many emails today are sent in HTML format. […] In the […] source code of an HTML formatted email lurks the danger: There, malicious code can be hidden which can already be executed when opening the HTML email […] without any clicking on an attachment.
I have read that it should be sufficient if I keep Thunderbird updated all the time, but I suspect it of letting through some malicious emails. This is because my old mail provider has been bought by a new company which does not offer spam protection at all. Furthermore, it does not scan emails for viruses, trojans or any other malicious code.
I know that even palin text mode does not offer a complete protection, but does such an add-on for Thunderbird increase my security so that I can read original HTML emails (that is, not in a simplified version of HTML) again?
