One Time Use Firefox

I dont see a reason for a one-time FFP.
Could you elaborate the idea?

"There is a computer disease that anybody who works with computers knows about. It's a very serious disease and it interferes completely with the work. The trouble with computers is that you 'play' with them!" - Richard P. Feynman

What use would this be? You can already do this with Firefox Portable. Just download it and run the self-extractor to extract the files. Use Firefox Portable as you'd like. When done, delete the directory and the self-extractor.

A "one time use" would save at most, what, one step?

One time use:
1. Download the EXE
2. Run the EXE to use the app
3. Close the app
4. Delete the EXE

Versus the portable setup:
1. Download the EXE
2. Run the EXE to extract the app
3. Run FirefoxPortable.exe to use the app
4. Close the app
5. Delete the EXE and the FirefoxPortable folder

So, all the extra work to compile a "one time use Firefox". And all the extra work to upload, maintain and support it on an ongoing basis would all be to save one simple step. Sounds like a huge waste of time to me.

If I do read this correctly, you want a version of Firefox that automatically deletes the files on the host computer after usage... isn't that the purpose of Portable Firefox? Unless you want one that doesn't modify the disk you happen to have it on with cookies, cache, etc, then can't you burn it to a CD?

I dunno, this is only if I did understand what you were trying to say.

Ever heard of Torpark, the modified Firefox Portable bundled with a portable version of Tor? Its default settings do not retain any information on the portable device. Of course, if you want a "one time use Firefox" without Tor, this is not what you want.
