The problem: I browse PM from http://perlmonks.org/ thus this very node for me is identified by the URL http://perlmonks.org/?node_id=725803. Now, if I do any operation (bringing back to the very same page) requiring a POST, up to a seemingly harmless /msg, then the "new" URL of the page will be http://perlmonks.org/?. Granted, generally this is not a problem since you either close the page itself, or follow links, and so on. But I often leave a tab open to "check it later..." And guess what? Crashes happen! Rarely enough, fortunately, but they do. FF does a good job of recovering after them, but on those tabs I'm basically redirected to the Monastery Gates. Or... it's even happened to me to bookmark some of them - and then I was bookmarking the Monastery Gates again, rather than what I really wanted.

I am aware that this would impose some overhead on the server; what's worst, in fact, is that the whole page up to the Free Nodlet must be loaded for the script contained in it to take effect. (In which case, as a tiny optimization, one would probably include it there as the first one.) Thus, as an alternative one may consider using Greasemonkey instead: I believe (rightly so?!?) that the script itself may stay pretty much the same with the difference that it could take effect as early as possible (rightly so, too?!?) and I didn't mention it in the first place because

• every time I did so, someone mentioned that "now there's the Free Nodelet;"
• it is much easier than one would want to enable the FN and JS code there than installing GM.
