Comment 2 for bug 2043757

In https://github.com/webcompat/web-bugs/issues/130808 it was suggested that I should upgrade to Firefox 120 and test with a new profile. After that, the pagedown key works fine. This suggests that it might just be my own fault, but I thought I'd talked with Colin about this before and he mentioned that he didn't know what caused it and never got time to get to the bottom of it, which suggests that it's more than just me.

Thanks
