Just browsing, I noticed that my ventilator was heavily working. "top" revealed that it was Thunderbird that was spiking the cpu, even though it had just been open in the background for a long time. My computer was up for 3 hours 15 minutes at that time. Indeed, the output of top below, sorted by TIME+, indeed demonstrates that thunderbird needed s=tremendous more processor time than other applications

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.
