Hi,

We are currently aware of this bug. Please see bug 1304360 for more information about the situation.

This issue can currently be solved by disabling hardware acceleration on Firefox.

The developers need your help to solve this issue. If possible, can you please enter about:support in the Firefox address bar. This page contains information about your system and Firefox. Please click the Copy text to clipboard button and paste the information into this thread. This will help the developers to discover the cause of the issue and create a potential patch.

Thanks in advance for your assistance with this bug. Sorry for any inconvenience.

One thing I am concerned with, is that by applying patch after patch after patch, Firefox may be headed down the road that caused Microsoft so many issues with Explorer. Eventually you will have 'overlapping' patches and they will start causing issues beyond the reason they were initially installed. And yes, I know that 'overlapping' isn't really appropriate for a description of software but it is the closest analogy I could think of at the moment. To many patches might wind up having unintended consequences that will render Firefox less efficient than Explorer. That has been patched to death and is now something most people want to stay away from.

BTW, the scrolling issue even showed up in this window when I scrolled down the information I posted into this text block.

Here is the information you requested from the about:support page for my PC. I hope it helps:

Experimental Features

Thank you very much sharing this information.

As I understand it, the issue has been caused by a change that was made in order to improve graphics rendering in Firefox. It appears to have caused some issues with older hardware and the developers are working hard to find a fix for it.

Thanks for expressing your concerns. The developers are constantly at work to provide users with the best browsing experience, while also creating the cutting edge technology for the browser. Unfortunately, the road is not always smooth and there are a few bumps.

Bumps are one thing, but patch after patch after patch after patch is doing nothing to make Firefox more reliable. In fact, lately it seems that every patch is bring MORE problems.

I had to hit refresh 5 times just to get to the bottom of this page to read your response, and then four more to get to the reply block here.

How do I roll back to an earlier version of Firefox?

We don't recommend using older versions because some of our patches are for security purposes, but we archive every Firefox version on our FTP server.

Mozilla cares about what our users have to say about the browser and we value our users' feedback. Sharing your thoughts can help to shape Firefox. Please feel free to share some feedback with us using this link.

Thanks.

Warning: Older versions may be vulnerable to security threats. Use caution when using old versions of Firefox.

Note: The Windows installers marked as stub may not work.

Can the most recent patch(es) be rolled back since the scrolling problem only happened after they were installed.?

Just now on ebay, I had to refresh over a dozen dozen times to go down one page. Other sites also have the scrolling issue, including this one, but for some reason, ebay seems to have more problems than most of the other sites I have visited.

Thanks for your assistance.

Henry

hi henry, please try the following (not in order to roll-back, but to solve the problem): enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named layers.allow-d3d9-fallback. double-click it and change its value to false and then restart the browser once...

Thanks, Philipp, that does seem to work - there had been some pages that I was unable to view at all because refresh put me back near the top of the page and no matter how far I tried to scroll down before the scroll problem appeared, the refresh put me so far up the page again that even in a couple of dozen attempts, I was unable to go any further down the page.

Now those same pages are viewable all the way down.
