I thought it is excellent, but finally i found it has performance issue.
If many tabs are opened for a long time (such as thousands tabs for more than 24 hours). The memory usage raises crazy high (such as 30GB) and crashes my applications. No same issue in other blockers.

Who have thousands tabs and long their Firefox should care about this issue.
And i believe general users would feel like 5 stars.

Nice

I love this addon works very well.

instant happiness. The Internet as it should be, free of interference. Just remind me to send money to people who make the Internet great: freeware teams!! We owe you a big one, guys!!!
