Difficulty using with vision impairments
I use Windows 10 with the High Contrast #1 theme because of my vision problems. I need light text on a dark background, otherwise I can only briefly glance at the screen and read text only with great difficulty.
Much of the text is a fixed color and is nearly invisible against the black background. This is the case with both webpages and the Tor's Options, where the check boxes look the same whether checked or not.
Also, some picture don't appear. This is a minor but related problem that Microsoft fixed in Edge a while back.
I just downloaded the Tor Browser v6.5.2 today, 5/26/2017.
