dark-background-light-text-extension: Bright flashes at the start of page loading meta bug

you didn’t reduce the flash, you KILLED it - at least on the sites i quickly tested, including heavy ones like YouTube

and this is without having to use …

#browser vbox#appcontent tabbrowser,
#content,
#tabbrowser-tabpanels,
browser[type=content-primary],
browser[type=content] > html {
    background: #000 !important;
}

browser.in-content.dark-mode is true by default in my case, regardless of browser theme setting

So, version 0.7.0 has been submitted to AMO (at the moment it is still waiting for review) which has huge improvements in this area. Everyone is encouraged to test.

In order to reduce bright flashes even more, do the following:

• Use Firefox built-in Dark Theme
• enable browser.in-content.dark-mode in about:config

+1. Very annoying. Hope it can be fixed. I am using Firefox 52.6
