Firefox Portable back off minor updates?

[MilesAhead]

For some reason sites like PortableApps.com when they update Firefox 27.0 to 27.01 then obliterate the link to 27.0.  Now I find Password Dialog Begone that worked in 27.0 does not work in 27.01.  But now I'm in a hunt for the 27.0.  I don't know why there isn't an "undo last update" button on these by now.

I found 27.0 portable and managed to overwrite stuff. I have 27.0 back and Password Dialog Begone seems to work.  Anyway I made a post on PortableApps forum bitching about them pulling the .0s as soon as they have a .01.  Especially with FF it's a royal pita.
