I am using Mozilla Firefox version 52.2.0 I installed Firebug version 2.0.19, it is in enabled mode.
When I am trying to print console logs, Firebug console does not print any console logs. Instead when I do Ctrl+Shift+J, it opens browser console, there I could see console logs. But I want to see console logs on Firebug console itself.

Is there any way of filtering out non-website warnings and errors?
I’m trying to use the console to troubleshot my JavaScript code, but the console is cluttered with messages from other sources such as Firefox addons. I some cases I can’t find my own console.log messages because of these messages.
Is there some sort of flag or setting to limit messages to the current site?
Only the Browser Console (available e.g. via Ctrl+Shift+J / Command+Shift+J or Firefox Menu > More Tools > Browser Console) shows messages coming from all different sources including add-ons.
The normal Web Console within the Firefox DevTools (available e.g. via Ctrl+Shift+K / Command+Option+K or F12 > Console) only contains messages from the current website.
So, you should ensure you're looking at the right console. If you're sure you are using the right console, then it's a bug and you should report it to Mozilla.
I've just updated firefox to a Firefox 51.0.1 (32-bit), and after the update console.log stopped working.
When I am tring to test some JavaScript variables using console.log(), it doesn't output anything.
As I mentioned in another answer, this happens because the Firefox internal APIs, which Firebug uses to output the data, have changed.
When you open the Browser Console, you'll see the following error:
TypeError: ConsoleAPIListener is not a constructor console.js:149:38
Note that, as stated in a thread in the Firebug discussion group and on the Firebug homepage, Firebug is discontinued and unmaintained.
I.e. it breaks more and more with every new version of Firefox and will quit working completely once multi-process Firefox is enabled. There is a blog post explaining the reasons.
The team behind Firebug advises to use the Firefox DevTools instead and there is a migration guide available.
In 2 steps:
disable or (better) uninstall Firebug
press F12 and enjoy the console and other Devtools
Why: Firebug is not regularly updated anymore, it often becomes obsolete with new FF update. Tools already available in Firefox (F12) are inglobating it.
I am new to firefox add-on development. When I open Mozilla browser from command line using "cfx run" to test my Add-on, it comes with a skype extension on it, which prints lot of error / log messages on console. Its hard to debug my log statements from them. How do I get rid of this Skype extension ?
Here is the error messages I get on console every time I run "cfx run".
Just uninstalled the skype On-click extension from programs. it worked.
Whenever I load my page into Firefox the Error Console shows:
I'm not purposely loading anything from Stack Overflow or Stack Exchange and the text "stackexchange" doesn't show up anywhere in my source. Does anyone know what these errors are?
You're using the (old) Firefox error console, which shows messages from all web pages you've got open, from the browser's own code, and from add-ons.
To see what's happening to your website only, use the web console instead. (Hit Control+Shift+K or Command+Option+K.)
All happened suddenly... 2 weeks ago..., the Firebug console stopped prompt me messages - all messages are not logged and it's doesn't matter if it's error/warning or info.
I Googled it all over and found that the Firefox console itself saying this message:
The Web Console logging API (console.log, console.info, console.warn, console.error) has been disabled by a script on this page.
But, my app does not override the console global object in any way and also, it occurs in any website I'm in - the console doesn't show noting except the HTTP outgoing requests I choose it to show me.
I'm sure it's Firebug's issue, I tried to downgrade Firebug to 1.11.x, it works for me 2 hours and the problem has back again.
I'm using: Firefox 23.0.1 and Firebug 1.12.1
