So something has changed since this workaround. It seems the suggestions are no longer sourced online or they are and the block still works, but they've added a local list as well.
Given that there is still no option to disable suggestions i've started looking for a means to disable them... and so far I can't seem to find or figure out where they're sourced or even how to just remove that from the dropdown.
Any suggestions from anyone? Or even better, Dev's give us an option to enable or disable them at our own discretion!! I don't need to see some random sites in my addressbar dropdown that I probably never want to visit anyway.
