Firefox starts normally in color. I move on to work within other applications (i.e. Microsoft Office products) and when I go back to Firefox to use the browser, the browser displays the website (whatever website I was on prior to moving to other applications) in black and white. If I open another tab in Firefox, it opens in color and when I return from the newly open tab, the original tab is now in color. Honestly doesn't effect the performance of the browser but is pretty annoying. Screenshot attached to this post. Thx!
