"Website not found"
do you have off road turned on. i find it buggy, it gives me the same behavior that you're describing. i turned it off for a fix.
"I would like to resize my speed dial blocks"
you need to turn on advanced settings. this will give option for speed dial thumbnail width and max # of columns.
as for searches, there are some extensions for for it (ex. duckduckgo). i haven't tried them, but maybe their what you need.
