I am using Lutris for Windows games (sometimes Windows applications, too) almost exclusively on my rig. It works perfectly fine.
SUSE & openSUSE also have a great documentation about the snapper snapshot tool which is also available in many distributions:
Arkenfox is not unmaintained but rolls a bit slower than Betterfox. But I will try Betterfox as well.
I also would vote for uBlock Origins. This is by far the best solution on the market. It blocks more than just ads and trackers. uBlock blocks also malware sites, popups, miners and other annoyances. Or you can also use it as an URL shortener tool to get rid of the tracking parameters in the URLs.
Something I've also been looking at more closely for a few days now is Arkenfox to hardening my Firefox more effective. Does anyone here has some experiences with Arkenfox?
