It has been discontinued too early; from an AdBlock Edge comment, titled "uBlock may be fast, but is rubbish":
> I've been using uBlock now for a while and while it is
light and fast, it's is rubbish to use. Exclusions are
idiotic, context menu controls don't work, default
filters selection is idiotic, it doesn't sync settings
like Adblock Edge does, I'm just starting to hate it.
> I'd too like to see AdBlock Edge continue its own
development path even if it's not the fastest or
lightest. It's still better than all other ad blockers...
