I added some info in the duplicate bug #221760. The most important what I found out is this:
When I let Firefox run with the disk activity and the 100% CPU for approx. half an hour, all problems are gone. Disk activity stops and CPU goes back to a normal level. When restarting Firefox, it seems the problems are not coming back, but after 10 min or so, the activity starts again from the beginning. This time only for a few minutes. After that I didn't had any problems anymore (for 15 min.). My urlclassifier3.sqlite is now 26,1 MB. -- [MASTER] High CPU Consumption https://bugs.launchpad.net/bugs/215728 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
