Yes, you do need a new computer. But for now, download the K-Meleon browser which has most modern features (or at least enough to load most sites) but can still run on old systems. I've got a computer from 1998. It even runs on that.
I use DocumentaryStorm.com
A user called Panzer has been listing tons of freeware (mostly windows but also Linux and articles) on the k-melon off topic site for years, I think he deserves a medal or something because I have never seen so many items published by a single person ever, currently there are 64 pages worth of freeware, the only problem is that he usually just lists the site and not always what the free software is or what it does, but worth a shot, although he (she?) is improving.
this sort of question gets asked every other day on this sub. so here it goes, Chrome and Firefox oth ended support for XP years ago. The only browsers that I know of that still support XP are Mypal, Centaury and Kmeleon.
Many on this sub use MyPal as their main, I would consider it to be the best of the three listed. Centaury is based off of MyPal but is designed for older CPUs (non sse2) and kmeleon supports MS Teams, something which MyPal lacks. hope this helps
One of the lightest web browsers in terms of RAM usage are: K-Meleon or Otter Browser (ignoring the old ones such as NetSurf, Dillo or Links).
On Windows try K-Meleon, this is the most lightweight modern web browser. You can also try Otter Browser, which is based on WebKit, so it's more lightweight than Blink.
It's not the browser, it's the website. Try using ad blockers, javascript-blockers, etc.
The big problem is that you're asking for "modern daily usage" - most people on this subreddit will be talking about older machines, and only web browsing on them occasionally - so using an older or less-feature-complete web browser is fine for most of us. We understand the security risks of running older browsers.
If you're doing this for a client to use as their "daily driver" - then the recommendations you'll get here might not be acceptable. Older browsers have security issues that you don't want someone doing "everyday" tasks with. And many "stripped down" browsers achieve their low memory and CPU footprint by removing key web functionality, rendering many websites unusable.
But, if I HAD to make a recommendation: K-Meleon
Just note that Windows 7 with 512 MB of RAM trying to browse modern website is going to be slow - no matter what browser you use.
it means you're on the chrome botnet, most likely. signed into gmail or amazon or facebook or another tech giant.
for a while, you couldn't pass those captchas with a browser that isn't chrome, edge, firefox, or safari. google didn't give a flying fuck:

google has been the new microsoft for a decade now.
I have no idea why you would desire this, but your best bet is to run K-Meleon (2019) or Opera 10 (2009). Seems like from the FAQ that K-Meleon can run YouTube, and it is built on Gecko, but you won't be able to install FF extensions.
You should keep an eye on Otter browser. It's in development and there is no complete version yet, but they specifically aim to recreate functionality/customization of Opera 12 and it looks fairly promising.
Another highly customizable browser is K-Meleon. I didn't tinker with it too much, but it seems to be even more configurable than classic Opera (12 and below).
There is one problem though, its development was stalled for quite some time and only restarted recently. Last stable version is somewhat outdated.
And thanks for mentioning Lunascape. I think I'll give it a try at some point later.
For slow Windows PCs I recommend Otter Browser (based on WebKit, which is more lightweight than Blink/Chromium) or K-Meleon (based on Goanna).
Sorry, but Ultralight no longer supports 32-bit architecture. For 32-bit Windows with little RAM I recommend K-Meleon on Goanna.
Does your processor have SSE2 (P4+, Athlon 64+) support? If it's an older one processor it may not. If not you'll probably be better off with K-Meleon. I doubt it's the ethernet driver if literally everything else works. It may be the GPU acceleration failing as one possability. The oddest bluescreen I've had so far was actually the XP AMD RAID driver being incompatible with a Samsung 860 500GB SSD which caused bluescreens during heavy HD activity but it could actually browse the web for a bit before it exploded.
I don't recommend it for a daily driver but people who want to try other browsers might find it of interest.
You are right, it is unstable. I probably would have done better by them to suggest they try K-Meleon.
You can try K-Meleon. It has HTML5 support and has Windows 98 support (no support starting with 1.6). You will need 1.6 for HTML5 support and that version does work with KernelEx. Just set the compatibility to "XP SP2" to get it to work.
I'm not sure how YouTube will run on a machine that old, especially since Windows 9x, including ME, do not support all the features needed for HTML5, but it's worth a shot.
Have a look at Otter Browser. It is very lightweight, based on WebKit, not bloated Blink. Or for Windows, try K-Meleon based on Goanna.
Oh, I see. It's just that... I read that K-Meleon dev(s) have been developing another version with an engine switch, though the development is considered unofficial at the moment. Also, Goanna engine was developed by at least one guy who forked one of Gecko versions and made it as its own. It's also used for the following Firefox-based browsers, Pale Moon and Basilisk, the latter still under development (i.e. beta).
Depending how lightweight you want. If you want a extremely lightweight browser for just viewing websites really quick, I made a quick browser in XUL, which is pretty much just the Gecko engine and a urlbar, which you can get here. You may also want to try out K-Meleon, which the UI is written in MFC instead of XUL, so it may be a little faster on older Windows systems.
