Firefox also recently started to flashbang me every time I open a tab. You gain some, you lose some.

What is flashbang?

> The non-lethal flashbang grenade temporarily blinds anybody within its concussive blast, making it perfect for flushing out closed-in areas.

If its the all white page on a new tab, you can add this to your userChrome.css

  @-moz-document url("about:newtab") {  
      body {
          background-color: #000000 !important;
      }
  }

It isn't. about:blank is solid white for a single frame whenever I open it, then it turns dark gray.
