The last time I looked was a few years ago, and slackware (for CLI only) and puppylinux (very, very basic GUI with a browser) were the top contenders. But puppylinux may be too basic for you, it did not support any of the standard browsers by default and likely has some compatibility issues with some sites.
No offense, but, how do you expect a web browser like this to be funded? Are you planning on funding it?
No default search engines, completely free open source, work on the modern web (modern websites stick to specifically designing their sites for whatever is popular, which tends to be the ones with the most funding/affiliation)
It's like saying every modern world wide network (e.g. Internet) sucks. Which it does, we pay per use (monthly fees, data fees), there's bandwidth limits everywhere, there's advertisements everywhere, corporations everywhere
Every grocery store sucks. Full of affiliates and advertisements. And then we actually pay for everything. And we even have to check ourselves out, after 'lining up.' Wait, every store sucks. Every online store sucks.
Yeah, you basically got it, don't use cheap PSUs (most cheap pre-builts are cheap PSUs) and if you do use a cheap PSU, expect something to explode/fizz out the more time passes.
I expect the average life expectancy of cheap OEM PSUs to be around 2-3 years. After that, you're on shaky ground.
You can likely extend the life of your electronics by keeping them constantly cool, and as dust/lint/pet hair free as possible (do yearly vacuum, use compressed air). This also greatly reduces the amount of combustibles in your electronics, meaning if something does overheat and die, there's nothing to burn.
As far as predicting it aside from it's lifespan, if you smell anything awkward, hear any funny noises, or notice any odd hardware behavior (blue screens, crashes, instability, etc) but especially "sudden shutdown and power-offs" then you know something is wrong. Just like if you suddenly get constant headaches, don't ignore it.
I've used every popular browser (chrome/edge/old edge/firefox/opera/brave/chromium/vivaldi) on Windows. Chrome works most smooth of the time without any funny issues.
Supposedly people said Edge is Chromium based, and is better, less memory usage, etc. I tried it, it just feels more clunky, takes longer to open, pages take longer to load. I also dislike the interface, chrome's interface seems more natural to me. And of course doesn't have the same extensions.
Firefox feels faster than chrome for certain sites, but I find it has issues with other sites. Might be because sites design for Chrome these days. Also Firefox like the original Netscape has random freezes and bugs. A lot less, but I find chrome just works most of the time with less problems.
An example site I can think of, off the top of my head, youtube works way smoother in chrome than firefox. I'm not a huge youtube fan but lately I've been trying to view content that happens to be only available on youtube. Opera has even worse youtube support.
I can't remember why I stopped using Chromium but I think it was a lack of extension support. I recalled it lacked something Chrome had that was important to me. If it's important to you, I can use it again so I can remind myself what it was.
For the record I do use Firefox as my backup browser, and I would say it's better than Chrome at some things (it loads certain sites faster, and has better extension support), and better privacy options, but overall Chrome works better for every site.
That said, from the example documentation.. <start>;
option of "v";
capture major { some of <digit>; }
".";
capture minor { some of <digit>; }
".";
capture patch { some of <digit>; }
<end>;
// v1.0.0
Show that to someone who isn't familiar with regex, and they'll have no idea what it means.
