Mozilla Firefox creates - and keeps on creating - an annoying "C:\nppdf32Log\debuglog.txt" file in your home folder, and keeping on deleting it is useless: every time you open Firefox, it's generated again.
A simple solution to this bug is to hide the file: in order to do that, create a new empty document in the same folder, and call it "hidden", without extension. Open it and copy the name (extension included) of the file (or files, and/or folders) you want to hide, then save and close. Rename the file by adding a "." at the beginning, so the final name should be ".hidden". Refresh the folder, or close and open it again, and the file will be hidden.
To see hidden files, or to see and edit the ".hidden" one, press CTRL+H on the folder, and again to re-hide everything.
