This bug affects me too. It usually appears on slow connections like GPRS or on connections which have some problems with DNS. Also it appears almost on all connections if i install dnsmasq. But i never seen it on Ethernet connections.
When firefox hangs it consumes 100% of CPU. This bug appears when i open new tab, close old, or just switching tabs. Usually clicking on the links doesn't affect it. Running firefox -g and beraking during the hang reveals nothing. It usually breaks in different places but often i see js_Invoke. It is very annoying per se, but the worst thing about it is the short-living X Server windows which firefox uses alot. Say if i open new tab and quickly click on menu "File" firefox opens system-modal menu window and hangs and the entire X server becomes unusable (does not respond to my actions) until firefox resumes. I can't switch to another application, the panels do not respond to my clicks and so on. The duration of the hang depends on number of open tabs. If i open 50 tabs it will be about 90 seconds. When i have 10 open tabs it's about 15 seconds. -- firefox spends lots of time hung https://bugs.launchpad.net/bugs/113201 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
