Since I have a laptop (Macbook Pro), I tend to leave it on all the time (albeit asleep). Thus, my browser tends to stay open a long time. In that time, its memory usage goes slowly up from around 400 MB to over a gig. I’ve also found that during activity, its CPU usage tends to suddenly swell and spike, going from around 30% to over 100%, usually within seconds. The peak, sustained for about fifteen seconds to half a minute, is usually 150%, but often goes up to almost 180%. During this time, of course, FF is useless.
I’ve since quit and restarted Firefox, and I’m assuming, based on my few minutes use so far, that this alleviates a lot of those problems. So my question here is, does it really make a difference to the symptoms mentioned above, or am I being “fooled”? If it is a “correct” fix, how often should I restart, so the problem doesn’t get so bad? Are the sudden CPU use spikes somehow harmful to the laptop?
Also, is FF14 any good? What’s new, and what’s good/bad?
Thanks in advance!
