Kind of a weird question, but here's the basic situation.
A while back I wrote a basic little todo app for use by some coworkers on an internal corporate network, and I was hosting it on a shared drive. For the sake of persistence without having to set up a web server, user data was being stored in the browser's localStorage.
Recently, the SysAdmins have been reworking the network drive addressing system, which has resulted in a change to the URL for my little app. Of course, this means that the page no longer has access to the same localStorage obejct, and anyone who has been using my app has now "lost" their data, even though it's still stored somewhere by Firefox. (We're all using Firefox 31 on Windows 7, in case that changes anything.)
So the question is, can I retrieve that localStorage data? My first thought, kludge though it is, was to have a user add an entry to their
hosts file to point the old URL to another file that will export the data (or, for that matter, point to a trivial file and grab the data manually in the web console). But, as you might have guessed, the
hosts file is locked down and we don't have admin rights.
As a final note, I am aware of the various Firefox addons that help with localStorage, but as I mentioned before this is all happening on an isolated corporate network, so bringing in an addon for such a trivial reason is a non-starter.
