Unfortunately I can't reproduce this problem, the page you mentioned looks differently for me and not blurry at all. Actually Moon PDF Viewer (PDF.js) uses browser rendering engine to display PDF content, so it can nothing to do if some fonts looks blurry at some zoom levels. You can try to play with browser settings (DirectX mode, etc), OS graphics card drivers, change zoom level or just use external PDF viewer if it suits better for you.

Don't hurry to close the issue... Could you please enable ClearType in Windows and send a new screenshot? Thank you!

I will not do it just for testing 'cause I hate ClearType and once enabled it takes too many steps to turn it off completely. Anyway as I already wrote I can't control font rendering from add-on in any way.
