I run Firefox in "dark mode". If I, for example, middle-click a bookmark in the bookmarks menu, it briefly shows a 100% white background before rendering the actual page (which is dark). In spite of me using dark mode.
The same thing happens when I open a new tab; 100% white background instead of matching the dark mode. This is extremely jarring.
As with so many things, Mozilla has crippled Firefox even this regard, so that you are only allowed these two choices for "new tabs":
- "Firefox Home (Default)". This one is ugly and "heavy" beyond words and also designed to spy on you. I refuse to have anything to do with it.
- "Blank Page". This means 100% white even though Firefox is in "dark mode". You'd think it would mean "whatever color is the basis of the current theme"...
Just above that setting, there is a similar preference for "Homepage and new windows". This one has the same choices as above, but also a "custom URLs" one! If that option had been available for "new tabs", I could probably have fed it a local HTML file which just paints a dark background, as an ugly but workable work-around, but that option just doesn't exist. I don't know if it has existed in the past.
How can I get rid of that "flashing light" as the brief white background looks like to me countless times a day?
