Re:Why I’m done with Chrome

uses 100% CPU even when idle
That sucks.
Anecdotally, I've never seen this, even when I had 1 external 4K and 1 external 2K connected. The whole OS was kind of sluggish at that point, but that was definitely asking a lot out of a puny integrated 3-year old laptop GPU so eh.
Just did a quick informal test with my current setup:
- MacOS High Sierra.
- 2015" MBP with no discrete GPU.
- Single 4K external monitor, 3008x1692 scaled resolution.
- uBlock is off.
With only a single blank tab open FF uses 0% CPU as expected. I opened three tabs: Facebook, Espn.com, and MSNBC.com. There was a brief flurry of CPU activity as the sites loaded, and FF's processes are now idling comfortably at 0-1%.
I repeated the process with Chrome and results were similar. One difference is that Chrome spawns 10x as many processes, but they seem to consume less memory each.
In both FF and Chrome, there's a palpable (500 or 750ms?) delay when switching tabs. In my experience a lot of Mac apps behave that way at scaled 4K resolutions.
I repeated this informal test in Safari and it "feels faster"; less CPU spike on initial site load and switching browser tabs feels close to instant.
