When I run this in the browser console:in Firefox, I get 58, in Pale Moon it's `undefined`. I'm curious why this is the case.
Why: after a previous thread about Pale Moon emulating Firefox fingerprints (here: viewtopic.php?f=5&t=31218) , I started looking into the differences between how Pale Moon and Firefox report fingerprints (and how websites/scripts do feature detection). One of the differences seems to be the JS engine reporting in the above example.
Here's a code snippet I found on Github:
CODE:
function getEngine() { const x = [].constructor; try { (-1).toFixed(-1); } catch (err) { return err.message.length + (x+'').split(x.name).join('').length; }}console.log(getEngine());Why: after a previous thread about Pale Moon emulating Firefox fingerprints (here: viewtopic.php?f=5&t=31218) , I started looking into the differences between how Pale Moon and Firefox report fingerprints (and how websites/scripts do feature detection).
