The normal function of the forward slash key in Firefox is to search in the current page. On the github web pages the key is redefined to do something different. I frequently want to search in github web pages and then always find myself typing in the “search or jump to” box, which is not what I intend to do. I hardly ever need that function.
I am aware that there are other ways to search in a page, but I’m used to using the “/” and hit it without even thinking. Web sites that don’t want to frustrate their visitors should leave well-known bindings alone.
So can someone please remove that annoying binding?
