It seems that someone believes that SuperUser has to have answers that solves all problems in all OS's. While I strongly believe that each answer is right on its own if it addresses the question issues and the plus value of being platform independent is nice as stated in Daniel's Beck answer, reality is not like that, there is no way that every problem can be solved in every OS the same way.
This metapost comes since it's not my first time where someone whines in comments that my answer (particularly to myself) aren't platform independent. While I would love someone comes with a method for any OS, as per the first paragraph isn't possible due significant differences between OS that makes inherently difficult to get such methods (in some cases, this is just impossible for some OS's).
The question that motivate me to make this post is this one which I on propose obscured some details with the alibi that more users could find it, and other users could answer them. According to this answer the asker has to play dumb as it doesn't know where the problem is, and since I'm aware that the method which I said in my question cited doesn't work in Linux/OSX, I left the question broad so people that might face the same issue (and I know will blame Firefox) could find it. Another example of this, but in this case the answers proposed works anywhere except Windows since there are just no tools (I'm aware of) to do what the question specifies in the way the question wants.
I've seen that SU answers any kind of general questions, preferring platform independent answers, but that doesn't mean that other approaches are wrong or out of scope just because they only works in 1, 2 or all OS's except one. If it's useful, and works for an specific case/OS, please don't start whining that is not platform independent and answer yourself with an answer that it is.
