to check your tiddlywiki version system use the macro <<version>> in any standard tiddler and it will render the current version number, you can also check the top of the HTML file in a text editor if for some reason the macro fails or you just don't feel like using it.
I could not find a copy of Tiddlyfox Alpha3 as the github repo only goes back to Alpha6 However I was still able to gather some interesting info: Using Firefox Esr 17 + Tiddlyfox a18 TWc - 2.8.x - Saved TWc - 2.7.x - Saved TWc - 2.6.x - Saved TWc - 2.5.x - Saved TWc - 2.4.x - Failed TWc - 2.3.x - Failed TWc - 2.2.x - Failed TWc - 2.1.x - Failed + Tiddlyfox a6 ... TWc - 2.4.x - Saved TWc - 2.3.x - Saved TWc - 2.2.x - Failed TWc - 2.1.x - Failed Reverting to Tiddlyfox a6 did indeed make saving in 2.4 and 2.3 possible. However worth noting is that my tests were done with 2.6.5 as it's the latest 2.6.x available in the archive: http://tiddlywiki.com/archive/ However it's worth keeping in mind that early Tiddlyfox versions may cause damage to non-standard characters in your TW save files. (I can't recall off the top of my head which version it was fixed in...)
