I was gonna say, I tried it a couple months ago and I’m pretty sure it hadn’t been changed since when I was using it in like 2012. I thought a theme might help so I checked out the available themes, and the “popular” ones were ones that felt like they were from back then too. Everyone remembers Firefox / Thunderbird themes from back then: frosted glass, photos of space, flames, lots of gradients, themes that look like wood for some reason, that gross red text on black-white gradient background. It was like the entire app was aesthetically trapped in the early 2010s, even the community’s themes.
I don’t have a gaming PC or anything, I just have a laptop, so ymmv, but performance in Linux, even of Proton games, is noticeably far better for me. Things are faster, I can crank the graphics settings up higher without lag, and my fan spins less angrily. Linux is just generally less resource-intensive than Windows by a very wide margin, so I think it leaves more for the game? Idk. All I know is it works better.
