Just curious, what do you prefer about Safari over Brave? Why do you use Safari instead of Brave as your primary browser? With the changes to Safari in Big Sur and the fact that it's completely optimized for the M1, I'm re-evaluating.
Same as badlydrawnboy, I’ve been using Brave for YouTube for a long time now, as it supported 4K videos in macOS versions in which Safari didn’t, and even though that’s not the case anymore in Big Sur, I’ll likely keep using it in that capacity as it’s a great way to ensure f.lux turns itself off only for YouTube (yes, I know of Night Shift, but I already spend too much time [re]searching, reading and writing on my computer and would rather use f.lux in extreme yellow/red mode for anything but video, photography and design work).
On top of that, Chromium-based browsers allow you to scroll down on YouTube even when in full-screen view; it’s just a shame that the website layout isn’t separated into frames, like in iOS/iPadOS, and that they likely won’t allow the iPadOS app on the Mac App Store or do a Catalyst app anyway. Oh well.
I may consider switching to Safari permanently if they fix at least that (it’s not like I open other websites in fullscreen mode that frequently, anyway, and that’s another configurable trigger for f.lux), which would be nice as I would likely gain windowed video mode as an added benefit – if they don’t end up gimping that functionality or haven’t done so already, as I’ve read somewhere here on MR, that is.
