From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041111 Firefox/1.0 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
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.
