Why I can not scroll menu drop down via mouse wheel to pick an option that is not visible?
I am using FF 22.0 on Windows 8. When I start scrolling on drop down menu which show the vertical scroll bar via mouse wheel event on my touch pad when the cursor is on the menu area, Firefox just close the menu. I don't install any add on related to mouse/touch event. Toggling Use autoscrolling, Use smooth scrolling, or Use hardware acceleration has no effect. This error behavior is not happening in IE 10. I just want some clarification whether this is a bug or I just failed to find some configurations that fix it.

Hello,
Try Firefox Safe Mode to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
(If you're not using it, switch to the Default theme.)
- You can open Firefox 4.0+ in Safe Mode by holding the Shift key when you open the Firefox desktop or Start menu shortcut.
- Or open the Help menu and click on the Restart with Add-ons Disabled... menu item while Firefox is running.
Once you get the pop-up, just select "'Start in Safe Mode"
If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for that.
To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.
When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.
Thank you.
Thank you for the reply. I tried your suggestion and found that the problem still exist.
For a check I choose random website and find this (drop down menu with many option usually found in form page)
There are many drop down menu in that website. But I can not use the wheel event in All Makes menu, for example, even in Firefox Safe Mode.
I thought this is my mouse driver problem, but the problem does not exist in IE 10 and Google Chrome 28.
Btw, I found this problem already exist several version back in FF stable branch. I am not using any other branch.
Does it work if you plugin a real mouse?
Does the scroll wheel on the touch pad otherwise work properly?
Try to modify the ui.trackpoint_hack.enabled pref on the about:config page from the default value -1 to 0 or 1 to see if that makes the touch pad work better.
Close and restart Firefox after changing the ui.trackpoint_hack.enabled pref.
ui.trackpoint_hack.enabled (-1)(-1:autodetect;0:off;1:on)
Whoa, I rarely plug real mouse.
> Does it work if you plugin a real mouse?
Yes, it works. And it works like I want it : the whole page scroll staged, not smoothly (Use smooth scrolling unchecked works properly).
> Does the scroll wheel on the touch pad otherwise work properly?
No, even if the real mouse still plugged.
> ui.trackpoint_hack.enabled
I have tried every possible values plus in Safe Mode. But no, wheel event from trackpad does not work.
Thank you for your suggestion.
