CPU-USAGE UNACCEPTABLE Rated 4 out of 5 stars

the reader is fine

but how the hell is it possible that thunderbird eats up to 28% CPU all the time on a Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz

this is UNACCEPTABLE, this is WASTING of ressources and from the view of a developer laughable - the feedsa re refresehed ina interval and between the refreshs the extension MUST NOT USE any CPU

This review is for a previous version of the add-on (1.6.1-signed).
