I can confirm the same behavior on Ubuntu 12.10, with encrypted home directory, running Thunderbird 17.05. Thunderbird constantly using 50-100% cpu, for hours at a time, only occasionally dropping below 50%. Creating new profiles, deleting various sqlite files, index files, etc does not fix the problem.
However - since others have ointed out that this seems to be eCryptFS related - I can confirm that moving my thunderbird profile to an unencrypted directory outside of my home directory seems to "solve" or at least greatly reduce the severity of the problem. If you are able to (given the security implications), I would recommend others to try this workaround. -- 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.
