I am having the same issue as Eric Bursley. Running Ubuntu 8.04 64-bit up to date. One window, good; two windows, okay; third window, 100% cpu. I can also reproduce the error on Ubuntu 8.04 32-bit as well.
I disabled all my add-ons, enabling them one at a time... and presto it turned out that the Google Toolbar was causing the issue. Running version 3.1.20080605L of the toolbar. I know this isn't a resolution, but more information is always helpful! -- Firefox uses high CPU for extended periods of time when spawning a new window with many tabs already open https://bugs.launchpad.net/bugs/66350 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
