Adblock Plus v3+ for Firefox is a complete failure. You removed the two options I used most:
1. Turn off Adblock everywhere
2. Turn off Adblock on this page only

There HAS to be a way to unblock a page temporarily without whitelisting.

Everybody hates version 3, the complete rewrite is a total fail. It used to be a technical tool that advanced users loved, not it's a dumbed-down phone app style piece of junk. You should have just made the necessary minimal changes to work with the new add-ons. Maybe came up with Adblock for Dummies completely separate from the real deal. I'm on Firefox ESR 52, and may just have to freeze in time so that I can stick with Adblock Plus 2.9 Firefox is going the wrong way, too. Nobody can leave well enough alone.
