When I receive an email that its suspects, maybe moved to spam folder by TB spam filters, but I want read it anyway, should be great to have a '''button''' in the 'main toolbar'/or in the 'header toolbar' for instance, to press and will active the "only pure text mode reading", only text will be loaded and showed. Should also fine a shortcut to activate or dis-activate that function. I searched for Thunderbird extension and on the search engines, but I'm unable to find something that does it. Thanks for reading and answer me.
