Hi, I am almost sure that my Firefox installation has been compromised. What happens is when I download files to me /home/username/Downloads folder some of the files get deleted. IIRC I started noticing this activity for the past 2-3 days. At first I thought may it was me who deleted them but now I am quite sure. This guy whoever he is doesnt delete all of my files.He/she deletes only p***. I have files of similar content stored in other folders of my HDD but none of them got deleted. So I can only guess that he had access to on the Downloads folder.I use noscript, adblockplus but still this happened. Even if choose to put the apparmor profile in enforce mode the Downloads folder will surely be within the reach of Firefox.By any chance if the attacker had gained access to my entire home folder I am finished coz I was stupid enogh to keep my pass key of the password manager I use.
