Firefox (at least 2.0.0.12) leaves some (irrelevant) data behind?
Greetings!
It's not a big deal, but looks like my Firefox Portable 2.0.0.12 leaves folder in %HomeDrive%%HomePath%\Application Data\Mozilla\Extensions\{ec8030f7-c20a-464f-9b0e-13a3a9e97384}
As I understand this ID means "Theme" (at least I found it in every theme)
Also with Flash Player 9.0.115 it leaves file with some related stuff in similar place somewhere in .\Application Data\Mozilla\ but this file disappears sometimes, so I'm not able to tell right now what was there...
Similarly I found .\Application Data\Mozilla\Firefox\Crash reports\ with two files:
