Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; fr-FR; rv:1.7.10) Gecko/20050717 Firefox/1.0.6
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; fr-FR; rv:1.7.10) Gecko/20050717 Firefox/1.0.6

In the pages http://impunite-zero.blogspot.com/ or
http://www.freenews.fr/index.php?itemid=2090&catid=92, the wheel scroll is very
jerky and slow even though the the page has been totally loaded. This seem to be
a problem linked to the handling of large images (?). This has been tested with
Firefox 1.0.5 and 1.0.6 on 2 PCs. I think that the behaviour is better with
v1.0.4. I works very well with IE 6 SP2.

Reproducible: Always

Steps to Reproduce:
1.Wait for the page to be loaded
2.Scroll down with the mouse wheel (autoscroll or not)
3.When large images are displayed, it becomes very jery

Actual Results:  
When large images are displayed, it becomes very jery and slow.

Expected Results:  
Smooth scroll like in IE6 for instance.

Default theme is used with no specific parameters regarding the display of web
pages.

I've rolled back to 1.0.4 and it works like a charm. After the upgrade to 1.0.6,
the problem reproduces. I might be wrong, but the issue seems to have appeared
with 1.0.5.

David, could you reinstall 1.0.6 and then start it in safe mode to make sure
that this problem is strictly extension related? http://kb.mozillazine.org/Safe_mode

I've tried in 1.0.6 safe mode, and the problem is still here. Has someone been
able to reproduce it with v1.0.6?
