Utter garbage (probably SEO spam page) that generates js errors like this:
Uncaught SyntaxError: expected expression, got '<'
If you examine the number and content of the errors produced by this site, including improper inclusion of google OAUTH stuff, it’s amazing that it works with … ah, chrome maybe. Dumpster fire of a website.
And as for modern, heavy, weather sites, look how clean, for instance, Germany Weather Radar Live Map - RainViewer is on the ancient SFOS browser. It’s just a properly engineered web site. Not quick on SFOS, but it renders cleanly with no errors.
99% of the web is garbage. And yes, we have an ancient browser, but I think we need a better list of ‘real websites’ that are a problem.
When 3.4 became 4.x I could no longer read a major newspaper. That got me looking. And I made a note of it here. That issue was fixed. But adding sites that are dubious/broken doesn’t help much.
