normally, in firefox, when press the "End" button, it goes to the bottom of the page.

for the last day or so, it takes a flashy cursor to the end of the line of text.

similarly "Home" takes me to the left of the page, not the top.

its significantly curtailing me enjoyment of the internet, which is quite curtailed enough, thankyouverymuch, as im sitting in my back yard stealing inconsistent wifi.

please?
