Extremely convenient for just going through things like witch hunt threads and blocking everyone with a pitchfork in their hand.

Unfortunately, it makes twitter gradually slow to a crawl as I scroll down. I believe there may be a garbage collection issue or memory leak when scrolling down long feeds.

Another, small bug, is the first time the icon is clicked when viewing a page, it will open the ... menu on that tweet instead of blocking. After manually blocking once it works normally.
