I can be very specific. This has been a problem for me for a bit over a year now. I am currently running SUSE Leap 42.1 w/ FF 48.0.1. I had been running 13.2. I have been running a 4 core 3.? GHz CPU (AMD) for the whole time, having added a primary SSD for swap (14GB). I also have 8GB RAM.
I have multiple FF windows open, pointing to various locations (2-16 tabs per window). Linkedin (which has its own problems). My gateway server (which I can config via web browser), etc. Flash causes me to have problems immediately, and so I have flash disabled. When FF finally slows down to where I can't type a message such as this, I Kill it, and restart it, only touching the pages I need immediately. Eventually it will slow to a crawl again. Right now it is using (per top) 106% of the system. If it were using 390%, it would be using all 4 cores and nothing would respond. But as long as FF is not using more than 2 cores, all other windows for other applications will respond nearly immediately. I've also noticed that FF appears to have a memory leak. Right now top is showing 5902668 for Virt and slowly climbing. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/38131 Title: Firefox causes massive Xorg CPU usage To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/38131/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
