Here are some problem: 1. Its been years and years. But still no "True Dark Mode", unlike Chrome. They finally did it. When we open any link in the tab, the white light still flashes. This doesn't happen in Chrome. Add-on section and setting page are still white. P.S: When a user choose "Default dark" theme, I think Firefox should make everything Dark. Right now, half of things are dark and haft of things remain white. There are students, teachers and many more people who read day and night on their screen. And Firefox is not helping them. Funny thing is, Why is this thing such big deal for Firefox? What are they waiting for? MS Edge has sexiest black themed browser provided like years a ago. Opera did it way back then. If Firefox stop providing trending feature, they will lose eventually. (A comparison screenshot is available.)
