i experience the same probelms - very annoying on an old computer with little cpu power. i use Release 12.04 (precise) 32-bit Kernel Linux 3.2.0-39-generic-pae GNOME 3.4.2
the high cpu is regularly after starting tb and goes on for quite a while (15 minutes +), it seems related to IMAP synchronization in a quite large mail account. closing teh message pane did not reduce the cpu load. please fix! thank you - andrew -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/927515 Title: Thunderbird stuck at 100% CPU Status in The Ubuntu Power Consumption Project: New Status in “thunderbird” package in Ubuntu: Confirmed Bug description: Just received the automatic update last night. Ever since, thunderbird is using 20-50% CPU constantly, according to top. Turned off global search and indexing to no avail. This is really bad for me as it's driving up the temperature of my laptop, runs up the fan noise and reduces battery time.
