问题
I'm working on a mobile website, and it works fine in the Android stock browser. In Firefox some JavaScript functions don't work. So I was googling for the error console. I found a support page wich gives information about the error console of an early version.
Is there an error console in Firefox for mobile version 14 (2012-06-26)?

Looks like it is hidden, but adding browser.console.showInPanel and devtools.errorconsole.enabled then setting both to 'true' in about:config will enable the console and preferences panel for JavaScript debugging purposes.
Here is how to find the error console icon:

It seems that the Error Console is deprecated, so bookmarklets are the simplest of the remaining mobile debugging alternatives:
- Android Console:
javascript:(function(){if((/android/gi).test(navigator.appVersion)){console={"_log":[],"log":function(){var%20arr=[];for(var%20i=0;i%20\""+value+"\"");}},"show":function(){alert(this._log.join("\n"));this._log=[];}};window.onerror=function(msg,url,line){console.log("ERROR:%20\""+msg+"\"%20at%20\""+"\",%20line%20"+line);}window.addEventListener("touchstart",function(e){if(e.touches.length===3){console.show();}});}})();
- Firebug Lite:
javascript:(function(F,i,r,e,b,u,g,L,I,T,E){if(F.getElementById(b))return;E=F[i+'NS']&&F.documentElement.namespaceURI;E=E?F[i+'NS'](E,'script'):F[i]('script');E[r]('id',b);E[r]('src',I+g+T);E[r](b,u);(F[e]('head')[0]||F[e]('body')[0]).appendChild(E);E=new%20Image;E[r]('src',I+L);})(document,'createElement','setAttribute','getElementsByTagName','FirebugLite','4','firebug-lite.js','releases/lite/latest/skin/xp/sprite.png','https://getfirebug.com/','#startOpened');
