@claudiom I ended up switching to using #ffssb with #Firefox under #OpenBSD to keep memory management in-check:

Of course, my workstation is old, slow, and only has 8GB or RAM (soldered!) While occasionally launching a couple separate instances of Firefox seems counter-intuitive (memory usage-wise), it helps me silo tasks/browsing and remember to clean up tabs when I'm done with them... because #ADHD.
