I think we’re talking about two different things here.
Put any search spec in the URL line and then hit Enter.
What then displays (normally) is a URL corresponding to the search results.
You could copy-&-paste that URL or bookmark it to preserve those search results (& then, if desired, re-run the same search without having to construct it again).
‘Saved search’ options, when available, do this automatically.
However, for some reason I am now not seeing URL’s in the URL line following the search, only the same search terms I entered before executing the search. I then have to right-click on that string to ‘request’ a URL. Never had to do that before.
The white areas are the blank boxes that are all that appear when I click on the orange Shields icon. The screenshot doesn’t show them exactly as they actually display: the first one is a ‘square’ box, the second a rectangle (that one shows pretty close to how it appears, it’s just missing the bottom border). The first one morphs into the second one.
The expected behavior (which clearly doesn’t happen) is that clicking on the Shields icon opens the Shields options to show their current status, allow changes, etc.
