Very nice, basic and usefull feature. All I need is to draw red lines on screenshots without installing a whole fat application on my system. Draw on page allow me to do this : I open the captured image in firefox, then draw what I need and finally capture the resulting image in my clipboard. Done !
Thank you Leonardo, nice work !

Drawing doesn't move when scrolling

this addon would be great if it wasn't for a little problem, that may or may not be related to linux.

the background cannot be set to a transparent color so it always is blocking the page's content, otherwise this addon has a lot of features while not being cluttered with menus.

does not work on PDFs and has no erase function also a way to type on a page would be good. finally, if it moved with the page when you scrolled it would be good. apart from this it works as you would expect

The drawing itself works great. I find the UI to be very confusing, and there is no eraser tool, you can only clear the whole drawing. Also, if the drawings could scroll along with the page, that would be nice.

add Clear all keyboard shortcut, will be perfect. I love it as far!

The best, simple app for drawing in the browser

Really good addon - almost perfect! That you can't draw over PDFs is inconvenient. (Is there a solution to this?) A text typing option would be nice. It would be better too if it scrolled with the page. But thanks anyway, I use it a lot in classes.
