I was wondering if I can use a canon ef 2x extender with my canon ef 75-300mm USM III lense? Thank You

No.

Isaac's right, it won't fit. You can use third party teleconverters with this lens but the quality will be poor. I use a cheap 1.5x TC with mine when I absolutely have to have a longer lens, but I don't expect much from the image.

The problem is with the cheap 75-300 lenses, and not just Canon's. The TC just magnifies the poor image qualities that these lenses have at the long end. I find that if I stop the lens down to about f/11 the image improves to the point of being so-so.

Yes. 75-300 + ET12mm + 2x extender + body. But without focusin on infinity =8-(

Yes, just as stated above, it will fit with an extension tube. Can you use it? I tried the EF 1.4x on my EF 100-300. I wouldn't advise it.

Come on, this is a stupid question!! Why on earth would you use a lens/TC combo where the TC costs more than the original lens?! TCs are extraordinarily picky about what lens they are partnered with and so on. For all that putting a 2X TC on a consumer zoom will achieve for you, you might as well buy one of those bottle glass 800- 1500mm F8-22 zooms. The results will be appallingly bad.

The simply truth of the matter is that there are no cheap shortcuts to long lenses. If you want a long lens, you have to pay for it.

I disagree that there is no way to avoid the need for long lenses. One short cut is to walk a bit closer. :)

Maybe not a great idea if lions are your thing though.

I never said that there was no way of avoiding the need for a long lens (unless you use it for perspective, etc). What I said was that if you want one (leaving that choice up to the user) there is no cheap shortcut.
