Folks,
I just want to let you all know that the most recent FireFox 58.0.1 includes a snapshot facility, you can select part or all of any webpage and take a snapshot.
The Advantaged for TiddlyWiki users is it is built in to the browser and saves png files which can be quickly dragged into your wiki to enhance its graphical appearance.
Or attach to your emails. :)
Regards
Tony
