Latest update (1.11.4) has firefox slow down to a crawl when loading script intensive pages. Firefox now becomes unresponsive for 30-60 seconds while loading the particular page I'm developing, was 1-2 seconds before latest update). Unfortunately I don't have information on which exact version I upgraded from. When loading the page without FireBug open, there is no noticeable lag. Since the site is internal corporate stuff, I cannot give you a link to reproduce :-(

This page makes extensive use of knockoutjs, which means a lot of function calls. My uneducated guess would be that this slowdown has something to do with function call debugging. 

Btw, thanks for an otherwise great tool!

i am using the same version, the problem is still same, lags in page loads when firebug panel is open, when its closed everything works fine.
everything works fine even while opening firefox's native console (ctrl+shift+k) or its inspector. but firebug makes everything worse.
its such a great addon , but really time taking now.

What we need is a test case that would help us to reproduce the problem on our machines.
(a test case is: set of steps saying what URL to load and what exactly to do to see the problem)

There are two reports in bugzilla (for Firefox) and there won't be a progress till we have the test case.


Bug 876075 - Firefox 21 slows down JSD and page load performance

Bug 875797 - Firefox 21 take long time compiling LESS CSS runtime with less-1.3.3.min.js.

I have the same problem.
I'm using Knockoutjs and LESSCSS with embed javascript compiler.

48sec for loading my less files ! (3sec with older version of firebug).

Open my html page, F12 to open Firebug, Ctrl + R to reload
and waiting... waiting... waiting...

No error in firebug's console

Please post details how to reproduce the problem to this bug report
https://bugzilla.mozilla.org/show_bug.cgi?id=875797

Otherwise we can't fix it

Hi there - think it's the same issue - just upgraded to FF 21 today and everything's a bit sluggish.
Especially the site i'm working on - it's not optimized and is unnecessarily intensive in the animation stakes that being said, yesterday I could develop with firebug open and today I cannot - it's too painful :-(

http://jljsolutions.co.uk/html5canvas/cleanstart/

as a test case (it's not finished etc) - load times were fine (considering there's a js file at 1MB) and animations ran nice and smoothly on my cruddy laptop, but now I can't work on it with firebug open.


Thanks for such a great add-on - I can't live without it!

I have the same problem - everything slowing down with opened firebug...
Re: Firebug 1.11.4 Sebastian Zartner 5/29/13 3:56 AM
"Me too" comments are not helping to solve the problem. If you have a test case, please post it together with the steps to reproduce in bug 876075.

I could reproduce the test case of bug 875797 using Firefox 21, though not on 22, 23.0a2 nor on 24.0a1. Tested this on a fresh profile with different versions of Firebug installed.
So could you all please try to reproduce your problems using Firefox 22 and let us know if you still experience the slowdown?

Hi there,

I saw a bunch of people post about slow downs when using Firebug 1.11.x
I had the same problem and this is how I solved it

I followed a tutorial somewhere to start a new Profile for Firefox.
I created a new profile and tested Firebug, the slow downs disappeared.

Workaround / Fix
It wasn't practical for me to stick with the new/blank Profile so I switched back to my default one with the slow-firebug.
I then removed the Firebug addon, restarted Firefox.
Deleted the 'firebug' folder from the my profile directory, restarted Firefox.
Browsed to about:config and searched for 'firebug'. Then right-clicked each setting and chose 'reset'. When I was done with all the settings I restarted Firefox.
After that I reinstalled Firebug 1.12.a7
Now everything is nice and snippy.

Conclusion
I think there are settings in about:config and files in the the profile directory that get's left behind when we upgrade firebug.
These settings/files appear to be the cause of the slow-downs.

I hope this helps someone, it took me a good while to fix. :)

Hi,

I have just tried this workaround and I can confirm it works here, now
everything is nice and snippy here too :)

Ray thanks a lot!

Hi,

just in case this might be useful, I've saved 2 screenies of the
firebug configs after removing Firebug, before and after the reset,
see the attachment.

Luca
Re: [firebug] Re: Firebug 1.11.4 mindrones 6/5/13 5:23 AM
Hi,

this was a false positive :/

I think that, by default and with configs being reset, Firebug starts
with Console and Script panels disabled, hence the apparent
workaround.
When enabling them again, everything slows down again.
Sorry for the noise.

Regards,
Luca

Hi There, dammit, I couldn't delete the post when I discovered the false positive.
Sorry for any confusion but the above workaround does not work. (as indicated by Luca as well).

Something else that might/might not be of interest to the devs though is that I'm experiencing the slowdown when
using jQuery + Google Maps API v3. When Firebug console is enabled, scrolling maps is jerky and slow. When console is off it's nice and fast.

Cheers.
Re: Firebug 1.11.4 Sebastian Zartner 6/5/13 11:56 PM
As I wrote in my previous comment it looks like this is actually a bug in Firefox.
So could you please test it out in Firefox 22 or above and let us know if that makes any difference?

Sebastian
Re: Firebug 1.11.4 Ray West 6/6/13 7:56 AM
Hi Sebastian,

I have attached a simple HTML file that uses Google Maps API v3. Please load that up and verify that you get the slow downs as well.

I have tested in the following:

Firefox 21, Firebug 1.11.x to 1.12.a7 - Slow down occurs
Firefox 22beta, Firebug 1.11.x to 1.12.a7 - Slow down still occurs.

Here's something I tried:
I disabled Firebug and enabled Firefox's built-in web tools. The map scrolled fine.
Then I used the build-in web tools Inspector, after that there was a small floating div around on of the google maps tiles. When I tried to pan the map the slowdown came back in pretty much the same way as in Firebug. (speed wise)
I ran the Profiler and it looks like 77.8% of processing was stuck in MarkupView.jsm:1072 - EE_Update(). Presumably this might have something to do with the slow-downs.

It does indeed appear to be a bug related to Firefox. Please verify.

Thanks!

The attached file, 2nd try.
Re: Firebug 1.11.4 David Hollander 6/6/13 9:04 AM
My solution was to downgrade to Firefox 20.0.1 until this problem is fixed.

There's a link on this page: https://support.mozilla.org/en-US/kb/install-older-version-of-firefox

After installing, make sure to go to Options / Advanced / Update and mark "Never Check For Updates". Obviously this is not ideal so remember to monitor this thread and upgrade once FF 21 or 22 has been patched.

Everything's fast for me again. Thanks goodness!

I was experiencing this same issue. Upgrading to Firefox 22 seems to have fixed it.
