Oh gosh. Okay. I figured that might be the problem. Also I increased the size of the font in the document and that fixed it. Thank you for your swift reply!That looks like you're upscaling the browser source, which is why it looks blurry -- you're taking the lower resolution of the browser, and expanding that smaller image to fit the scene.
Ideally what you want to do is set the browser source's page size to be big enough for the intended size on the canvas, so you're dealing with natively larger elements from the browser.
