311498 - flash ads cause improper down scrolling when going back a page

Status: RESOLVED WORKSFORME

(Firefox :: Bookmarks & History, defect)

Description

[Tom Sorensen]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050908 Firefox/1.4

Starting in 1.5B1 (I did not see this behavior in 1.0.x) if you go back a page
on some sites with flash ads the browser will not re-render at the correct
location on the page.

To replicate -- go down about halfway or further on the mentioned site (I can
replicate it easily here), click on a link, then go back (alt-left or whatever).
The page will be at the proper location for a split second and then scroll down
below where it should be. Very annoying. I've confirmed that this occurs both
with and without Flashblock 1.33a installed, and the scroll amount seems to be
directly in proportion to the size of the embedded flash ads higher up on the page.

Firefox 1.5B1, Flash plug-in 7.0 r19

Reproducible: Always

Steps to Reproduce:
1.Go to http://www.bluesnews.com
2.Scroll down below at least 2 flash ads
3.Click on a link (local or remote) to go to a new page
4.Go back a page in history

Actual Results:  
Page was scrolled down below the previous location

Expected Results:  
Page should have rendered at the previous location

Can you reproduce this with the latest Firefox 2 or 3 build and the latest Flash plug-in?

If not, please resolve the bug as WORKSFORME. Thanks!
