712311 - Javascript (exec + html5) is slow on my website

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[leaderpol]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:9.0) Gecko/20100101 Firefox/9.0
Build ID: 20111216140209

Steps to reproduce:

I write an grapher application in HTML5 (http://seg.deberranger.com) and FF9.0 is going very slow on it. Chrome is OK, FF8.0 OK and IE 9.0 OK. I think there is a bug you could find by debugging my site.


Actual results:

FF is frozen


Expected results:

The render 2D ans 3D will works fine

Comment 2

[Tim (fmdeveloper)]

How can we test this? What are the steps to reproduce?

Does the issue still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode

How about with a new, empty profile? http://support.mozilla.com/en-US/kb/Basic%20Troubleshooting#w_8-make-a-new-profile

Please post the contents of about:memory when the slowness occurs (as a text attachment to this report)

In safe mode it's better but very slow and FF frozen sometimes.
Try a comparaison between FF9, FF8 and Chrome.
Chrome is better (~5FPS) than FF.

I've put un my website some samples.

This one is very slow on FF and supportable on Chrome.

If you wan to test it use the load button on http://seg.deberranger.com (2nd from the icon list) and load the .crb on you hard disk.

Regards.

I have similar problems with javascript pagination project for http://www.outletpc.com. Everything fine in Chrome.  Has anybody figure anything out?

My problem was with webgl not only html5.
For me this case is now close.
