WFM in WinXP. Although the extension Smoothwheel stops working on the file list
area.

Same problem on this page:
http://www.linux-noob.com/forums/index.php?act=home

I cached the page to:
http://www.philippwesche.org/mozbug/linux_noob_index.htm

This time it's a table nested in a div this time, try in the area after
"Thanks!" aka "Thanks!"

The previous instance is a <pre> inside a <div>, so the problem would seem to be
with the handling of divs.

Confirmed working in 1.0.7 and current pre-1.5 nightly.

Excuse my density here. I'd forgotten it was a Linux bug, and didn't have access
to a Linux box for a while. The bug persists in 1.0.7. To give another page
where it operates,
http://forum.websitebaker.org/index.php/topic,1601.0.html

I'm beginning to wonder whether this is an interaction (in the statistical
sense) between Ff and X.org. I'm using Archlinux - just to be sure, can someone
confirm whether the bug occurs in other distributions?

The mouse used is an optical but wired Logitech Pilot, standard model, should be
very widespread.

So, it still persists in 1.0.7 on Linux, but what about in the current nightlies?

I have the same problem with my GMX webmail (gmx.net) on Linux (Gentoo Linux) with  1.0.7. 

Tthe folder-view of the webmail-pages work without problem, only if I open a single mail and try to scroll up/down with the mousewheel, then the wheel stops working. When I open the next mail, the same happens again.

So it seems to be triggered by something in the page. I also see the problem on the ubuntu-page.

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.12) Gecko/20051217 Firefox/1.0.7

The same page works on Windows XP.

When I try to reproduce this with a test-case by downloading the html to a local file, I cannot reproduce the problem. Also if I download a complete webpage from my webmail-account and open the file, I cannot reproduce the problem.

However if I put it onto a webserver, I get the problem again, see http://dstadler.org/TestBug300278.html

Comment 8

[Dominik Stadler]

This seems to be related to "<pre>" and the CSS-element "overflow: auto;"

I have reduced the testcase to http://dstadler.org/TestBug300278a.html If I remove the pre-element or the CSS-style, the page starts to work.

Can somebody on Linux test with 1.5 and report if it still happens there?

Attachment: testcase

This works for me in latest trunk.

This I guess was resolved by whatever fixed bug 279117.
Thanks for reporting.  Please reopen if you still see the problem.
