PSA: Enable browser.urlbar.suggest.calculator in your firefox about:config so typing math expressions in the address bar shows the result with an option to copy
@easrng oh, that's great. Any idea why it's not enabled by default??
@easrng ok thank you but how do I calculate the second derivative of a function 🙃
Nice! If that also supported unit conversions it'd replace 99% of my use of DDG-as-calculator.
@josh yeah i wish it supported qalc's features or something
@josh ooo actually turn on browser.urlbar.unitConversion.enabled
Nice! Giving that a shot. Seems to be missing some units sometimes, but it's a great starting point!

Any idea why this isn't enabled by default? I don't see any tracking issues for it in Bugzilla.
