But git is stored in git, so to sneak stuff into it in order to break git's security, you would have to break git's security first.

On the other hand, hiding malicious changes in otherwise legit-looking commits is a whole different issue that has nothing to do with github or git.

You are not quite correct. Firefox is tri-licensed under the MPL, GPL, and LGPL. Furthermore, the MPL is a free/open source licence (approved as such by the OSI and FSF).

Actually, the Firefox name and icon are trademarks of Mozilla. They are openly available, but you do not have rights to distribute non-official builds of Firefox carrying the trademark name and logo without permission from Mozilla. This is compatible with the GPL because (IANAL) the GPL does not care about trademarks, only copyright.

Actually you can't. Vista and 7 no longer have the 16-bit subsystem. (You can probably run them in XP mode, but that's just Windows XP in a VM) The earliest applications you might be able to run are from Windows 95.

That's not really possible. If you have filesystem access, you can install the add-ons the same way the browser does. How would Firefox stop that?

However, Firefox does show on startup if any new extensions have been installed - that's the way this thing was spotted.

You can also get 1 GB for 5 pounds with the Internet Monthly addon (which are taken from your topped-up money, so you essentially pay 10 pounds and get 1.15 GB + 5 pounds for calls or a few more MB). Or just top up 5 pounds online and get a decent 1 GB for 5 pounds, 0.5p/MB.

I have on two occasions submitted PDFs exported natively by OOo to turnitin with no problems whatsoever.

That said, turnitin needs to die a horrible death.

They are working on multi-process support which should get you exactly what you're looking for. The project is called Electrolysis. The first step will be that plugins (Flash, Java, etc) will be in separate processes, which will be added in a 3.6 security update supposedly.

I considered that, though he said "plugged into" which might imply two external ones.

Out of curiosity, why do you need two?
