My experience with this bootstrap/jquery page in Firefox (v39, latest updates installed) has been unusual as it always seems to jump to the bottom of the page upon clicking.
Upon inspecting the code, I couldn't find any JavaScript responsible for this behavior nor was there any obvious CSS that could explain it.
I am puzzled by what is causing this issue and would appreciate some insight into why this is happening.
P.S. Interestingly, in Chrome, the same jumping behavior only occurs when the browser width goes below 1300 pixels, leading me to suspect a possible conflict with the bootstrap layout.
