Works! Here at the tail end of 2023, most similar solutions have broken due to "changes in twitter's api" and not been updated, but this one stands tall. I was worried because it worked so fast it almost seemed like it couldn't possibly have actually worked, so as a control I opened the profiles of a few random likers for another tweet in another browser on another device, use the block all button, then refreshed the profiles on the other device. Sure enough, they were all blocked. Big thanks to the creators.
