Has John T or anyone else considered compiling a one time use Firefox which leaves no traces on the host machine, or on the portable device it is run from?
Opera has a one time use edition at www.kejut.com/operaportable but which still uses folders created in the local settings temp folder. Opera says all information is completely destroyed upon shutdown but there are doubters to this.
As I understand Firefox, all temp files are created in ram which is then lost upon shutdown making Firefox the more secure of a possible onetime browser.
All ready done, or a good idea?
