Overall I like this extension because of the controll it gives, but each open window/site needs to maintain its own state (enabled/disabled) and display the icon for that specific state. Right now, changing the state of any one open window changes the icon on every other window such that its state and displayed icon are then out of sync. Changing the state of any open window means you can no longer trust the other windows displayed icon to be telling you the truth. I can't tell you how many times I have tried to reactivate javascript for a window that was already enabled, and only to find that I had to change it back again, thus changing all the icons on the other open windows.

This is a good addon, but due to some bug it constantly blocks Google's services like gmail and google keep, although the plugin runs in blacklist mode and google is definitly not there.

It happens after each browser restart

Would recommend.

1. It works.
2. I wish there were an option to remove the logo from the URL bar: it serves zero purpose. (If the developer could make another addon that moved the refresh button to the URL bar, that would get a 5 from me.)
3. The other icon (the green tick) is a really bad icon: A green tick could be used for just about any addon and it would vaguely make sense, which is precisely the problem. A green tick doesn't distinguish it at all. I switched to this addon after YesScript stopped working after the Addon apocalypse. That has great icons: a white scroll, which you'll be familiar with if you use Windows, that turns black once you blacklist a site.
4. I wish there were an option to disable auto-refresh. If that's too hard, disable the refresh. I can refresh a page myself.
5. Weird behavior within the addon's options when using drop-down box for changing to blacklist, but that doesn't matter really.
