Firefox strange way of handling downloaded items

[LinuxNoob]

firenice03 is correct it is an icon that has my recently downloaded items.

What type of files?
Mostly video files from youtube << I believe I corrected this through the Firefox applications tab under preferences.

I was able to play *.mp4 files before but now it seems that all files trigger the system update (tried to get a snapshot) It also happens if I try to open file location instead of executing it from the same list.



The file type that seems to be giving me grief is *.zip file. Those seem to initiate an system update. I believe thats the only file right now.


update : It seem to be all files now. Just like before


Oh and here is the content for the file defaults.list you asked for Jerry.
