```
[{ "trigger": { "url-filter": ".*" }, "action": { "type": "css-display-none", "selector": "body" } }]
```

2. Open a new tab
3. Enter "google.com" (or any other website) and press Enter

Hi Alex!

Is there any update on this issue?
Is there anything I can do/provide that might help you?

I have the same problem = (

[Andrey Meshkov]

After all it appears that the bug is not that serious.

It exists only in case if "trigger" contains "resource-type" field:
```
[
    {
        "trigger": {
            "url-filter": ".*",
            "resource-type": ["document"]
        },
        "action": {
            "type": "css-display-none",
            "selector": "any selector"
        }
    }
]
```

Removing "resource-type" fixes the issue. This is still a bit weird, though.

This is indeed pretty weird.
