Sorry if I'm not supposed to post these. This is just a usability request though. When someone backs out of a find, by backspacing, they're left at whatever the last partial word FF found was, instead of being taken back to where they started. So for instance, If I'm searching for the word 'bandgap'. I type 'band' and FF moved me to where that was in the page. Then when I typed the 'g' the Findbar turned red indicating that the word wasn't in the page. So I backspaced out of the search, but I still somewhere unkonw in the middle of the document. It's disorienting and non-friendly behavior. I think FF should probably take you back to where you started the search. Not sure if the same behavior should exist for using 'Escape' since that may be the normal way to back out of a search that was successful too.
The "bug" still exists.
