I can't figure out how to download and install ABP on Firefox. I paid for a year, but keep getting prompted to upgrade AB to ABP.

Stopped working on YouTube as of today. Otherwise it's great.

Bin zufrieden, wundere mich nur, dass ich nach einiger Zeit Adblock neu aktivieren muss!

This Addon Blocks Channel Names from appearing on YouTube.
Every YouTube video that is viewed has it's Channel Name hidden, and there is no way to tell what Channel the video is housed on.
Disabling Addblock Plus and every video's Channel Name once again appears properly.

This Addon Breaks YouTube from operating properly.

Fails to "ignore" on many legitimate sites, and continues to block them.
