>From the comments above it looks like there could be several distinct causes of Thunderbird running at 100%.
In my case, I have just upgraded to Raring and the situation has got worse. It now happens pretty much every time I try to minimise or close Thunderbird. Thunderbird will just sit there for hours running at 100%. For me it's worse than that because I use ibus to switch languages and it causes ibus to refresh itself continuously too (see bug #1162008), thus making the computer practically unusable. My key observations are that: - Now I have upgraded to Raring, this 100% cpu usage is (sometimes) happening when I minimise Nautilus or Firefox too. When this happens, compiz is also near the top of top. - I have tried using the default xorg graphics drivers and the proprietary nvidia ones, and the issue is the same. - My colleagues that have similar setups to me (same graphics card, 64bit, similar processors) don't have the same problem. However, I am the only one that has an encrypted home directory. So, to me this implies that the root cause is some incompatibility between an encrypted home and compiz/Unity, which Thunderbird also happens to be a victim of too. It may just be that Thunderbird tries to write more configuration/database stuff to the (encrypted) home directory when it is minimised than Nautilus or Firefox and so it's a lot more noticeable for Thunderbird than for the others. -- 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 Mozilla Thunderbird Mail and News: New Status in The Ubuntu Power Consumption Project: Confirmed Status in “thunderbird” package in Ubuntu: Triaged 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.
