Firebug console incredibly slow

[AntranigBasman]

For the last several version of Firefox, I've noticed extremely bad
performance when sending logging messages to an open console in
Firebug using console.log(). I didn't notice exactly when they began,
but it could have been around the Firefox 8 or 9 era. Upgrading this
week to the lastest Firefox 11 and Firebug 1.9.1 doesn't improve the
issue, and neither does installing Firebug on an empty profile.

As an idea of the scale of the problems, a page which loads in a few
hundred ms with no logging, takes 5 seconds with about 80 logging
messages, and 30 seconds with a few hundred. This is sort of back in
the realms of performance of the IE8/9 console logger - and Chrome can
show both sets of logs in well under 1 second.

Has there been some huge regression in logging performance some time
within the last few months?

As mentioned above, I am using FF11 and FB 1.9.1, this is a Windows 7
machine with AMD 64, but colleagues have reported similar problems on
MacOS as well.

Thanks for any help,
Antranig.

Please try Firebug 1.10a5
http://getfirebug.com/releases/firebug/1.10/firebug-1.10.0a5.xpi

(it's an alpha, but pretty stable)

...and let us know whether is better.

Thanks, yes, the performance is hugely better, by at least 2 orders of
magnitude. Thanks so much for the pointer, and for your work on this.
Cheers,
Antranig.

Firefox 11 is now producing slow messages for dojo and jquery 1.6.2.  Performance was fine in Firefox 10.

Did you try Firebug 1.10a5 as Honza wrote?

I have been experiencing very similar issues using FF11 and FB 1.9.1
and the minified version of jQuery 1.6.2... I upgraded to 1.10a5 and
didn't notice much of a difference. I was able to resolve the issues
by using the unminified of jQuery 1.6.2.. all newer versions of jQuery
also worked!

Could you please send me your test page so, I can also test this?
One related bug is supposed to be fixed in1.10a5

Thanks!

I was having similar issues, switched to 1.10.0a5, and found immediate
improvement. Then when a certain kind of error occurred both Firebug
and the page performance became incredibly slow whether logging to the
console or not. I'm trying to pinpoint the error. Only way to clear
it is to restart Firefox. Using FF 11.0 and jQuery 1.7.1 minified. If
it happens again, I'll try tecfreak's idea -

If you send me your test page so, I can see the problem on my machine
I'll fix it.

Page is password protected - could send privately if you wish

this line with incorrect syntax trying reference a datatable object causes the problem in jQuery 1.7.1 minified, but not in non-minified

var nTr = dtbl.fnSettings().aoData[ a[row] ].nTr; // this line causes firebug/firefox slowdow, must restart Firefox after to clear

I've had the very same issue for at least 4 years/ They don't fix it. Can't test my game with the firebug console in firefox lol. Gotta use some alternate tool in chrome sorry i used to like very much firebug but it seems to have an issue with chrome. Don't worry this is nothing compared to the challenges I face against mobile browsers.

You have just excavated a five years old thread.

Note that Firebug is officially discontinued. Read more about that in the Mozilla Hacks blog. People are recommended to use the Firefox DevTools instead.
