A year or so ago a web search turned up a link that I visited and then the javascript on the page locked up vivaldi so hard that my machine crawled to a halt and I couldn’t even get activity monitor to load to force kill it and had to hard boot the machine.
Since then I’ve run with JS off by default since lord knows what lurks on any given page, even “credible” ones. I continue to be saddened by how many pages show nothing or just a “JS required” message. :(
