Email mail clients such as mu4e are not perfectly suited to view HTML emails. I usually try to view it in Emacs (using Emacs' own HTML redinging enging shr) but revert to opening the email in a browser if it is not readable. However, one problem with this approach is that the browser will load images, java scripts, and other remote resources references in the HTML potentially compromising my privacy. The question is: how can I prevent remote resources from being loaded?
I considered to filter the HTML to remove java script and images but it turns out that there are so many different ways to load remote material that filtering is not feasible (CSS, Adobe Flash, ...). So I think it would be better to open the HTML in a browser (tab?) that doesn't connect to the internet. Is there a way to do this?
