User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13

Sometimes on a Mac system (with no addons/no personas and plugins) upon trying scroll with a scrollbar/scroll wheel/touch pad, it would freeze the web page. No scrolling would be done. I have tried turning off Smooth Scrolling/Auto-scrolling feature.

Reproducible: Sometimes

Steps to Reproduce:
1.View a random webpage
2.Try scrolling
Actual Results:  
No scrolling performed by browser.

Expected Results:  
It should scroll.

If I switch to another tab and then come back to it, it automatically resumes scrolling.

Are you perhaps scrolling over a flash or other plugins content area when the scrolling stops?

Many times it was a Google search page.

Worse: scrollings themselves made ​​with the CSS attribute "overflow: hidden;", are" wrong"(wrong is subjective). The result of Opera is congruent with the case where the scroll bars are visibles. MSIE6 displays a "wrong" result in both axes, while for FF, the results on both axis are different.
