Clicking the ruler turns the whole page white, but then click-dragging the mouse just tries to move the page content. A huge waste of time. When I tried to go to the support site to file a bug report, it says 403 forbidden. Failure everywhere.

Sorry you didn't enjoy your experience with MeasureIt. Since it adds HTML/CSS/JS to pages it may conflict with certain sites but, overall, doesn't seem to do so. Apologies you got a 403 error as I've been migrating my extensions to a new domain. I'd love to do some testing if you want to email me what site you were using it on I can take a look.
