I most often have this situation when using Google, however, it occurs in other situations, too: After going back one step in the browser history, the links on the page are not "usable", the page has to be reloaded in order to be functional again.

Reproducible: Sometimes

Steps to Reproduce:
1. Do a Google search
2. Follow a resulting link to the corresponding WWW page
3. Go back from this page to the Google search result list
4. In many cases, now no other link in the result list is clickable
5. User the reload button -> everything works again as expected.
