Thanks for posting this -- I would have missed it.
Coincidently during the past week I've been testing a bunch of browsers in search of something decent to put on a couple of ancient (2002-03) machines that I'm going to donate. Have been getting more and more fed-up with Firefox over the last couple of years. It kills me to say that because I've been a loyal user since the Netscape days. Don't care much for many of the recent UI changes, but what bothers me more is that it has turned into a major resource hog. About 1 - 1 1/2 years ago I switched to Pale Moon as my go-to browser, which is basically Firefox with old UI and slightly tweaked engine. It's better, but still a pretty heavy browser. That's not a problem on my newer machines, but older ones still struggle.
I'm no fan of Google, so won't use chrome.
Tested Chromium a couple of years ago and didn't think much of it, so haven't bothered this time. However, I did test a Chromium-based browser called
Slimjet and was very impressed. Not crazy about it being close-source, but performance was noticeably better on ancient machines. Youtube videos played pretty well with it (some even in full-screen with minimal choppiness, which was a shock to me), vs. the same videos being almost unplayable with Firefox in standard size. (If they were open-source, they would have won my vote in the poll.)
Midori is light-weight and fast, but is probably too lacking in features and seems prone to crash a lot.
QupZilla is one that I have used as a backup browser for last couple of years. Over that time, my impression is that it keeps getting better. It's a viable go-to browser for under-powered computers and even does a reasonable job with Youtube videos (Slimjet's performance was better though). It uses less resources than Slimjet, is quick and has a reasonable amount of basic features. My main complaint with it is font rendering is not as good as others.
Tested a few others, but none of them were newbie friendly -- so no good for the computers I'm donating.
Long story short, those computers will have Firefox and QupZilla (as light-weight alternative) loaded on them. And I voted for QupZilla in the survey even though I primarily use Pale Moon (and may switch to SlimJet) myself. Wanted to give them some credit for making a pretty decent light-weight alternative. (If SlimJet were open-source, they'd have gotten my vote.)
