With the transition to Nova, UX has removed the icons that appear within the Downloads details dialog that is available for blocked downloads. Temporarily, this was handled with `display: none` behind the nova pref. However, the best way to remove the dated styles once Nova is rolled out.

Note that the icons still need to appear within the Downloads panel, so the rule should be modified from this:
```
#downloadsPanel-blockedSubview[verdict="Insecure"] .downloadsPanel-blockedSubview-image,
#downloadsPanel-blockedSubview[verdict="Malware"] .downloadsPanel-blockedSubview-image,
#downloadsListBox > richlistitem[verdict="Insecure"] .downloadBlockedBadge,
#downloadsListBox > richlistitem[verdict="Malware"] .downloadBlockedBadge {
  background-image: url("chrome://global/skin/icons/error.svg");
  -moz-context-properties: fill;
  fill: var(--icon-color-critical);
}
```

to this, for example:
```
#downloadsListBox > richlistitem[verdict="Insecure"] .downloadBlockedBadge,
#downloadsListBox > richlistitem[verdict="Malware"] .downloadBlockedBadge {
  background-image: url("chrome://global/skin/icons/error.svg");
  -moz-context-properties: fill;
  fill: var(--icon-color-critical);
}
```

**Remove "not Nova" code in downloads.inc.css**
There's a few lines of code that target the pre-Nova version of the panel and subview. This code can be removed.

**Stylesheet cleanup**
At some point over the years, code specifically for the blocked subview made it into `downloads.inc.css`. Since there is an entire stylesheet dedicated to the blocked subview, `download-blockedStates.css`, it makes sense to keep all blocked subview code there. Move any code specific to the blocked subview from `downloads.inc.css` to `download-blockedStates.css`.
