Agree..
Please add the feature to remove the nstmp files from the Thunderbird profile folder. I just found that I had 10GB of these nstmp, nstmp-1, nstmp-2, etc. after running CCleaner to try to free up space on my hard drive.
This is a link to the show that these files are only temporary and can be deleted without recourse to Thunderbird.
