Wait, what? For me, Chrome is utterly unusable for “research sessions” (aka routine browsing). It starts chewing up resources like crazy and completely falls over when I try using it for any amount of time with 25+ tabs open. Google’s non-search webapps seem to be particular offenders: more than a few tabs of them open in Chrome brings my fast laptop to its knees.

Firefox is good up to about 100 tabs, but becomes a big CPU and memory hog and inevitably crashes after a day or two.

In Safari, I routinely keep 200+ tabs open for weeks at a time with no problem (though eventually I start running out of system memory; not sure if there’s a slow memory leak, or if badly written websites just require indefinitely large amounts when kept open, or what; usually by that point there’s a new security update to install in any case).
