I'm having trouble navigating through a Firefox page with my keyboard. I'm not able to use the following buttons in navigating up and down the page: up/down, home/end, page up/page down. Instead I have to use the mouse. This extremely inconvenient as I have gotten used to using the keyboard and specially when reading this wesbite as every page contains up to 25 posts.
Also, a blinking cursor has appeared in Firefox. I looks like the cursor from Office Word. It's a
blinking cursor and it's treating the Firefox page like a text document. IOW, when I move it by the up/down/left/right buttons it moves letter by letter or line by line. It moves too fast and somtimes skips 10 posts in a fraction of a second.
BTW, this problem is on Firefox only. IE is working fine.
