The machine is 1.8 GHz, 512 MB, Win98SE with an ATI Radeon 8500 and is normally quite fast. The problem goes away when I disable images completely. The same site also runs smoothly in Internet Explorer 6. Strangely, as long as the same site is open in IE, Mozilla and Firefox run normally. When I close IE, Mozilla again slows down. I initially suspected a Flash object on the page, but I Adblocked it and the problem continued. Firefox also loads the site with no issues on a couple of Windows 2000 machines that I use. The slowdown is most noticeable when scrolling the page up and down. The difference in CPU usage with images disabled and enabled is about 35% and 98%, even when the window is idle (not actively scrolling or clicking anything). Reproducible: Always Steps to Reproduce: 1. 2. 3.
> Strangely, as long as the same site is open in IE, Mozilla and Firefox run > normally. We've had several reports of such issues... as far as we can tell, IE is doing something to put either the drivers or the hardware in a faster mode. No one's been able to figure out what, exactly, and whether it's even part of Microsoft's public API.
Are there other bug reports with more details or possible work-arounds? This is easily my biggest annoyance with Firefox.
This is an automated message, with ID "auto-resolve01". This bug has had no comments for a long time. Statistically, we have found that bug reports that have not been confirmed by a second user after three months are highly unlikely to be the source of a fix to the code. While your input is very important to us, our resources are limited and so we are asking for your help in focussing our efforts. If you can still reproduce this problem in the latest version of the product (see below for how to obtain a copy) or, for feature requests, if it's not present in the latest version and you still believe we should implement it, please visit the URL of this bug (given at the top of this mail) and add a comment to that effect, giving more reproduction information if you have it. If it is not a problem any longer, you need take no action. If this bug is not changed in any way in the next two weeks, it will be automatically resolved. Thank you for your help in this matter.

This is still an issue and easily my single biggest complaint about Firefox (until the 1.5 beta). I haven't seen the problem on three Windows 2000 machines, so it might be specific to 98. However, Boris Z. mentioned "several reports of such issues".

You tried it in Windows 98 as noted in the bug?
Looks like that particular site has been cleaned up fairly recently. Try going back in time to the page that was there when the bug was reported. http://web.archive.org/web/20040922235943/http://www.ci.dublin.ca.us/
(In reply to comment #7) > You tried it in Windows 98 as noted in the bug? Sorry seems to have missed it. Reopening. But due to this statement in the comment #0 >Strangely, as long as the same site is open in IE, Mozilla and Firefox run normally. I suspect it's a driver issue.
Still an issue in FF 2.0. To KL: Note from the earlier discussion that IE scrolls around the same page much faster and that while IE is open, Mozilla/FF also gets a lot better. If there's a problem in IE but not FF then it doesn't seem like strictly a driver issue.
Ideally this would still get fixed, but it's no longer an issue for me after recently upgrading to XP Pro.

This was logged as a Windows 98 issue, and it looks like you're on XP, in which case it's not "WFM". This was still a problem right up until I switched to XP a couple weeks ago.
James, you are quite right it's not WFM. Almost any way you slice slice this it's invalid, I simply didn't list the reason(s) ... If the problem is the flash player then it's invalid (and there are plenty of flash bugs with good testcases). if it's a driver, likewise. if it's strictly w98 it's wontfix because w98 is not supported. If it can be reproduced on something other than w98 then there may be some hope of addressing it. Otherwise it's essentially dead. (I could test it on w98 myself but it's simply not worth the time.)
