I don't use any A/V plugin in TB, and TB is what is using 100% CPU while downloading the new message headers. All other processes are at 0% CPU. The only other non Windows processes running all the time are the Sun Java Quick starter and Java update scheduler. >> I don't recall having this performance issue with dovecot 1.0.15.

Yeah, that would be nice. The config editor does highlight all user defined settings in bold though. > Did you make any manual config changes to TB using about:config or > applying manual changes to user.js? The only TB change I recall making via about:config was to disable condstore. Since updating to 1.2.11, which fixes condstore support, I reenabled it. That said, I've made a number of about:config changes in Firefox, which, IIRC, shares config info with TB. However, the about:config changes I've made to FF are all http tweaks, such as pipelining, etc, which shouldn't affect TB. I do have the TB CompactHeader and Enigmail plugins installed, but I wouldn't think these would cause this slow header download issue, as they deal with display. AFAIK they aren't in play during new message header downloads. -- Stan
