I have a early 2011 MBP on High Sierra. I recently reported a bug to Mozilla that I was experiencing in Firefox. They couldn't reproduce it, but it was essentially the integrated graphics are so old in this machine that their new render engine was causing major glitching issues. The solution was to hard code the use of the previous engine for older laptops. This, among a number of other issues made me decide to recently upgrade... but hearing about these old-but-new features makes me want to cancel my order and wait it out a bit longer.
