Windows XP x64 SP2
AMD Athlon 64 X2 5000+ with 4GB RAM/1TB HGST SSD on nForce 630a
My benchmark scores are awful especially compared to what I saw above... Tested with a default profile. Chrome 49 scored more than twice as well, which is from over a decade ago at this point. The actual processor is from December 2006, so pretty much time-relevant to XP itself, I suppose.
I'll be honest, even the latest Firefox versions are not great to use on modern OSes, purely because SpiderMonkey is just not suited for the modern web's 'run everything as a JavaScript app and reimplement everything in it' philosophy (and for other reasons, like the fact
Firefox is Chrome for people who think they're fighting The System, but it's actually funded by The System). (Interestingly, the author of that particular page I linked uses Pale Moon on Slackware, which amuses me considering Moonchild is actively hostile to Slackware users...)
For older, pre-2015 websites that didn't decide to jump on this bandwagon (yet), I guess I can see this being useful, but then again, literally any browser would do for those sites as long as it supports the relevant certificates. Not to mention that the amount of UXP forks is beginning to make the whole Pale Moon scenario look like
this... actually, isn't that just the Windows Legacy communities in general?
The Edge-mimic theme is actually quite nice and really close to how I remember the original MS Edge looking, which IMO was a pretty underappreciated browser back then, however, though the menu bar being enabled by default on XP is probably not a good idea (and it shouldn't overlap the top bar like that, either).
Also, I'm really struggling to pronounce the name consistently. Maybe it's just me.
Don't let any of this put you off, however. It's not my fault web developers have an intellect that would make
Nep look like a genius.
