It can consume a lot of CPU. You can turn it off through Edit>Preferences>Advanced>(general tab) Uncheck 'use smooth scrolling'. You could try turning off hardware acceleration too if that is causing problems, though normally you'd want that left on.

I've had some different problems with graphics drivers and dropped back to the default supported X.org X server display driver to test if the driver was the issue. Could It be a mouse driver issue ? In Setttings, does Mouse and Touchpad recognise your mouse? Dave </blockquote> I don't have a problem with ubuntuforums but I do have a very similar problem with Facebook. Firefox is my main browser (currently 18.01). it will start off normally and I can access facebook without a problem but over a period of 24 hours (my PC runs 24\7) Facebook will become unusable, cpu usage is bouncing all over the place and scrolling is jerky. I normally I have to close just the Facebook tab give it a few seconds and then restart Facebook in a new tab. All other sites I access are OK, I have had this problem for about the last 4 version of Firefox that has been released, annoying but I just live with it. Tim </blockquote> cpu usage shoots up to 80% for me on ubuntuforums, that's the only site (i browse a lot). <fieldset class="mimeAttachmentHeader"></fieldset> </blockquote> </body> </html>
