''locking this thread as duplicate, please continue at [https://support.mozilla.org/en-US/questions/1077906 /questions/1077906]'' When I type over the URL place to do a search or type an actual URL, the text disappears under blocks of color. this also happens around the icons in the tool bar. this goes away when I restart in safe mode my mozilla. I unistalled all add ons from my computer. i use no theme. none of this has worked to have the URL placeholder corrected.
