Thunderbird - high CPU usage and freezing at version 52.6.0
Dear all,
I have experienced a high CPU usage (and also software freezing) using Thunderbird since the update to version 52.6.0, before the update - with the earlier version - there wasn't any problem.
Thank you for help.

Still In Windows safe mode, start thunderbird in safe mode - https://support.mozilla.org/kb/safe-mode-thunderbird
Does problem go away? Please post to let us know results.
Unfortunately it doesn't... I experience some freezing under Safe Mode as well, the CPU load is lower, but compared to idle mode, it reaches 50-60% immediately when Thunderbird freezes for a while.
Gerix,
Please post results of going through https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems
Using TB 52.8.0 @ macOS 10.13.4 a similar problem still occurs. This reminds me of the "How to stop Thunderbird hammering your CPU" blog post you (Wayne) responded to. Should we try what's suggested there?
