No, but I think it is less of a risk to count on Firefox not having a zero day vulnerability that SR will use to target me versus a script marketed to drug traffickers not having a backdoor that will target me. Strictly speaking it can be much more secure to run your application than to access SR, as you can not access SR from behind an air gap. On the other hand, it is dangerous to talk about things that are true in theory when they are extremely unlikely to be true in practice. Also I believe it is theoretically possible to compile any interpreted language (and likewise to interpret any compiled language), so indeed python and even ruby can be compiled, it is just not the common use of Ruby (and in fact I don't know how to do it) but apparently can be done more practically with Python.
