Description of problem:
once i installed firefox 1.0.1 i noticed an immediate slowdown.  i am
using firefox on a p2 366 mhz laptop so things like this effect me
greatly.  the slow down is most noticeable when i browse to a page and
try to scroll down using my mouse wheel.  there use to be some lag
maybe one second to a second and a half now it will go 3 to 4 seconds
depending on how far down i scroll, which is unacceptable.  there is
also more lag when i drag the scroll bar down the page.  i hoep we can
get this figured out soon.  i had to roll back the rpm to double check
and make sure i wasnt crazy and i still noticed it.

Version-Release number of selected component (if applicable):
firefox 1.0.1

How reproducible:
Always

Steps to Reproduce:
1.upgrade firefox on older laptop
2.scroll down page
3.
    

Actual Results:  less than one second lag

Expected Results:  3 to 4 seconds lag

Additional info:

just ask ill respond very quick usually

Comment 1 Christopher Aillon 2005-02-26 14:42:02 UTC
This is caused by firefox now enabling smooth scrolling by default
which takes a little more CPU speed.  You can fix this by disabling it
in your preferences.  Advanced > Use Smooth Scrolling, and uncheck it.

ahhhh.   that makes sense.  i wonder if that could be set to turned
off by default so idiots like me wouldnt think its a bug.
