Page down to the bottom of the content took 75 "page down key" presses to view the last line of the 100 lines of content. Tested: removed the following from styling -moz-border-radius:6px;-moz-box-shadow:5px 5px 15px #bbb, -5px 0 15px #bbb;-webkit-border-radius:6px;-webkit-box-shadow:5px 5px 15px #bbb, -5px 0 15px #bbb; Result: page down worked fine, 2 page downs to see the last line of content, scrolling normal speed, no lag or latency. Reproducible: Always Steps to Reproduce: 1.Create a normal HTML doc with a <div> with style -moz-border-radius:6px;-moz-box-shadow:5px 5px 15px #bbb, -5px 0 15px #bbb;-webkit-border-radius:6px;-webkit-box-shadow:5px 5px 15px #bbb, -5px 0 15px #bbb; border:2px #0DBCDF solid;display:block; position:relative; background-color:#FFF;padding:5px;z-index:100;height:509px; top:0px;left:0px;width:720px;overflow:auto; 2. Create 100 lines of content i.e. <br/>test 100 times inside the <div> 3. Load the page in Mozilla and try scroll up or down on the scroll bar and it lags and is extremly slow 4. page up or page down for the <div> in focus and content isnt viewed as expected Actual Results: Mozilla froze for a while after the test and started to consume a large amount of ram, continued to do so until I closed it. Restarted Mozilla - restarted a new session and tried the test again. Exact same results. Expected Results: Fast scrolling as per the div without the shadow and moz radius styling
