Rated 5 out of 5 stars

Simply excellent -- great way to stop scripts and other malware. Twice incoming emails from trusted users -- which looked suspicious and I did NOT click on any links in them -- twice viewing them messed up my T-bird settings (in LINUX!) Tthis extension makes it so convenient to preview email in plain text, determine if the message is legit, then view in HTML with one somple click. Kudos! If you manage to get "allow HTML" to "stick" to approved messages permanently, so much the better!

This review is for a previous version of the add-on (3.6.3).
