Regrettably, appears to do nothing at all, leaving FF still as the only major browser it is literally impossible to do javascript development on.

Unfortunately, it doesn't work at all :(

While not updated in a while, this add-on still works perfectly with 102esr. This add-on is worth its weight in gold for tweaking CSS. Mozilla really should provide an about:config setting to force cache refresh. Until then, this add-on is perfect for the job. It goes one better by allowing per-domain cache control. Very nice.
