I have online notes for a class I am taking and what I have been doing is opening the PDF and using the draw tool to take the notes. The only issue is it kinda sucks on Firefox. I love Firefox and use it exclusively however when I am writing notes it makes me frustrated and doesnt work very well. There is no undo feature or even an eraser so if i make a mistake i have to deal with it, cause when you write unless you unclick the draw tool all of what you wrote gets clumped together into one "box" meaning i can't delete one part of it if i wanted. I would have to delete the entire thing. It is nice to be able to change the size of what I drew but it would be significantly better if I could undo or erase like in MS-paint. I still use firefox for browsing and stuff but I had to switch to chrome for taking notes on PDFs, just to make my life easier. Thank you.
