Created attachment 8824696 TB 45.6.0 high CPU load when connecting to unreachable IMAP server
Here is the requested performance profile with TB 45.6.0 on a Mac. (The setup for getting it was a bit involved, using both FF and TB, but ok.) Note that anyone can easily reproduce this CPU misuse: Just set the IMAP Server Name of some account to an unreachable IP address like 1.2.3.4 and try getting emails from there. This bug is apparently very low-level in the Mozilla network layer and has a number of related bug reports touched again recently also for FF. -- 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/109943 Title: Thunderbird: high CPU usage from progress bars Status in Mozilla Thunderbird: Confirmed Status in thunderbird package in Ubuntu: Confirmed Bug description: Binary package hint: mozilla-thunderbird When sending a simple and short email with Thunderbird via SMTP the CPU is used intensively. This seems not to be necessary. If the sending failed and an corresponding error message dialog appears, the CPU is still being used. When pressing ok to close the error dialog the CPU is fine. This suggests it might be related specifically to the progress bar. Such behavior is especially annoying on a laptop where you can hear the CPU usage because of a starting fan.
