Previously if I pressed F6 while browsing the web I'd get the entire address selected and could quickly change sites. Now, this behaviour has changed so that it only moves the cursor to the beginning of the omnibox without selecting the existing text.
For example, if I'm at superuser.com and want to switch to Google, I'm used to just pressing F6 and typing google and pressing Ctrl+Enter, which resulted in www.google.com. If I do the same now, the address is www.googlesuperuser.com.
How can I revert to the previous style?
