This is a common problem for firefox and google chrome.
When I want to navigate the webpage with the left and right arrow key, this happened:
I am in a forum, which of course have many pages. When I press the right arrow key, the browser jump to the next page automatically. When I press the left arrow key, the browser jump to the previous page automatically. This is not an expected behaviour, I expect it to navigate with the page left and right.
What's wrong?
Win xp.
