Comment # 5 on bug 1160331 from Maximilian Trummer

Something I didn't realize at first: this bug can also lead to data loss.

1. create a testfile e.g. "importantnotes.txt"
2. save any file from firefox under "importantnotes.txt#treatedascomment.png"
3. "importantnotes.txt" is overwritten

And no error is shown in this case, the user has no idea unless they are aware
of this bug.

And another variant that would happen more often:

1. save any file from firefox in the folder /home/user/Documents/#notes/, where
"Documents" is a symlink to somewhere else
2. Firefox treats everything after # as a comment and will overwrite it,
replacing the link with the downloaded file.
