Regarding autocomplete as I type in the search bar...

Love Firefox by the way... So, autocomplete in the search bar is often helpful, don't get me wrong, but it redefines the delete/backspace key to be context-sensitive. Now, sometimes it does what I expect and backs up one, erasing the character I just typed. However when autocomplete ghost text is present, that same key removes the ghost text only, leaving the character I'm intending to remove. This is enormously inconvenient as I now must watch to see what autocomplete is doing and adjust my behavior to comply. Were I designing I would not make the delete key dual purpose context sensitive, instead I would do both at the same time! Delete what I just typed and remove the ghost text. Safari started this, I complained and of course got no response. Subsequently I noticed the same behavior in Firefox. My suggestion, request, is that search delete key behavior not be decided for me. Either make this Safari behavior a settings option, by default is OK, so that I can choose, or (my preference) delete both ghost and previous character with a single keystroke! Best regards and keep up the good work. Dave
