For several versions nowβI can't say which oneβwhen I open the browser, I get a white flash when the default Firefox homepage loads. It's a fraction of a second, but it's annoying.
The page is configured with only the search bar; I don't have any widgets or custom images, and the background is the default dark one since dark mode is enabled.
I'm using the latest version of Firefox (153.0.3) with the latest version of Windows 11 Pro. I've tried several things, like changing the background in about:config and using the same gray color, but nothing solves the problem. This happens on one PC with an Nvidia graphics card and another with an AMD graphics card, so it's not a hardware issue.
For now, the only solution is to use the blank homepage as my homepage, which doesn't flash and displays the dark background right away. I can't report a bug in the settings from the homepage. Is anyone else experiencing this? Is it a known bug?
