On latest nightly, starting about 24 hours ago, when I type things into the search bar I randomly get taken to a piece of my browser history instead of searching for the term in question. If I hit back and then enter it repeats the behavior. If I hit back and prepend a ? then it relays the entire line with the ? included to my search engine. I think there is an issue with the auto complete because it is not indicating that it is actually completing but that seems to be what is happening. Maybe this is also related to the cursor lag I have seen lately in the search bar. You can be typing and it will display letter out of order or seemingly so until it catches up. Basically the cursor doesn't move in the search bar like it used to. That's been going on for over a month.
