Yep, when i have to test something in Firefox i always forget that to search in Google (or in other popular site) i can't just write it in the address bar.
And it always remember all my sites so to go to hacker news i just write an "n" and it writes the rest... and i can even delete the suggestions with shift+delete.
So yeah, i also don't have any idea what the parent comment was triyng to say.
God I love chrome's autocomplete. HN is 'n', reddit is 'r', Facebook is 'f', gmail is 'g'... It's such a great usability feature. Google's approach with Chrome seems to be making the browser as invisible as possible, and I love it.
