What happens if you leave this? The UI people like the effect.

Hi Robert, here's some screenshots with 0.9 alpha:

I think it's a little hard to read without the blur filter. Maybe a little less
alpha?

It's unfortunate that we have to ditch the blur. But, yes, let's try a little
more alpha. I think it looks good overall. I'll leave it to your judgment to
find the right magic number.

Also please test an extension bubble.

This is at 0.96 which seems more readable to me

What do you think?
Here's a screenshot with adblock

the WebView is completely opaque so doesn't look any different
