I noticed that the following conditions must be met for the problem to occur:
1. The tab with the slow loading file must be selected (mentioned above) 2. The tab bar must be displayed (with default configuration, the tab bar will not be shown if there is only one tab) 3. The tab must be the first (leftmost) tab, although it sometimes also happens in other tabs. I can let the CPU usage go up and down by dragging the concerning tab to the left and back. It doesn't seem to depend on add-ons or settings, I tested it after renaming away my ~/.mozilla directory. -- [feisty] 50% of cpu when a page is waiting to load https://bugs.launchpad.net/bugs/106199 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
