I would like a “View Page Source” button, because I think, that would be better just one click instead of two clicks (right-clicking context menu and then click view page source item).
I, too, would truly appreciate this. The javascript trick I use in Safari doesn’t work in Firefox and the “view-source:” url doesn’t work either. So I guess I’ll have to keep using the javascript bookmark I’ve set up in Safari for now… unless the Firefox folk would be so kind…
