I feel very similar.

However, I have come to believe that it is not possible for a browser anymore to “save” a website these days.
Too much is being done with pulling in and rendering data on-demand, so the only way to preserve is the view as a screenshot. … until OCR gets powerful enough to re-create all text faithfully (and with AI maybe even the interactive parts somehow right?) or someone figures out how to freeze and export a tab’s memory in a portable and archiveable way (i.e. a Virtual Machine snapshot for a page view :-*( using up dozens of megabytes if not even gigabytes where a few kilobytes should suffice).

So many websites today will end up in the “big black hole of lost information” 🙁
(and to find many from before is very hard if not almost impossible even today already)

For public websites archive.is and web.archive.org seem like our best bet but for anything personalized …

And no offense to you, but my sentiment is that “modern and elegant” is a very, very large part of the problem why the “modern” web is just a shit show nowadays. Just last weekend I had to spoof Firefox to be whatever-other-browser-agent-string-worked just to make a purchase. “Modern” web shops are a menace for not using simple technology (because “people” “expect” bling everywhere?!). A few percent more in Firefox’s declining market share won’t stop those practices…

If you can influence them in a way, as WEB DEVELOPER(s), AT THE SOURCE, with your customers and stacks that you use, PLEASE do!

Oh, and if you should become to know a Gecko-browser with (old-style ;-)) sane UI and without marketing, please let me know…

Good luck to us,
Georg

PS: I loved to use Palemoon for many years but too many sites became absolutely, totally and utterly broken, so I grudgingly went back to Firefox…

PPS: I guess I’ll be back on Palemoon + Chromium for all those other sites 🙁
