Works like a charm, the only thing I'd like to see added in the future however is something along the lines of being able to set up a cooldown after reaching block limit in which the extension won't block accounts but still add them to the queue.
I know the block cooldown is there to circumvent that however even after setting it up to one block a minute I ended up getting logged out from twitter after a few hours so they might've messed with the block limit and cooldown for it.
On top of that, I just think it could be useful to have the block cooldown and a cooldown for the amount blocked just in case anyone would like to have people blocked as quick as possible
