My experiment with switching from Firefox to Safari on my MacBook has been interesting. But the MacBook crashed again yesterday, while using Safari, in the same way it had been crashing while using Firefox. So that pretty much rules out Firefox as the reason for the crashes. That’s both good and bad news. On the good side, it means I can go back to Firefox. On the bad side, it means I’ve just about exhausted software-related reasons for the crashing, which means I’ve probably got a hardware issue.
Apple might announce a new MacBook Pro at their event next week. If they do, it might be time to replace this MacBook Air. (Even if they don’t, it might still be a good time to replace it, likely with the current iteration of the Air.)
Getting back to the experiment with Safari: I think I’ve decided that I could use Safari as my default browser on the Mac, if I needed to, but I’m still more comfortable with Firefox. I’ve been using 1Blocker for ad-blocking in Safari, and that works OK, though not as good as uBlock Origin in Firefox. And I haven’t found any other Safari extensions that really give Safari an advantage over Firefox in any way. The other big thing for me is 1Password integration, and that works just as well in Firefox as it does in Safari.
