about JavaScript

However, JavaScript is what probably killed TenFourFox quickest. For better or for worse, web browsers’ primary role is no longer to view documents; it is to view applications that, by sheer coincidence, sometimes resemble documents. You can make workarounds to gracefully degrade where we have missing HTML or DOM features, but JavaScript is pretty much run or don’t, and more and more sites just plain collapse if any portion of it doesn’t. Nowadays front ends have become impossible to debug by outsiders and the liberties taken by JavaScript minifiers are demonstrably not portable. No one cares because it works okay on the subset of browsers they want to support, but someone bringing up the rear like we are has no chance because you can’t look at the source map and no one on the dev side has interest in or time for helping out the little guy.
