Hide harmful sites from Google search results.

Main function

- Blocks with arbitrary URLs (for example, on Twitter you can block by account)
- Blocks by keyword
- Control of hide(soft block) and erase(hard block)
- Prevent blocked sites from being seen even for a moment
- Card type search results, news, video can also be blocked

Limitations
- Because we prevented it from being seen even for a moment, the layout will collapse somewhat. Resize the window to get back to original."
