I believe this can occur if you have a profile you've used in newer Firefox and then go back to an older Firefox.  I am able to reproduce this on my own profile that has used 36 if I try it in 35 or older.

The root cause I believe is that IndexedDB occasionally requires a version change[1] in the underlying DB it uses internally.

Once this happens, it's not possible to access the data with an earlier version of Gecko.

I will try to at least detect this case and add a message about it, so it's less surprising.

Jan, is my understanding of the IndexedDB schema version correct?

I believe it's possible to "reset" WebIDE's project list from IndexedDB by removing:

<PROFILE>/storage/persistent/indexeddb+++fx-devtools

Please backup your profile before trying this!  More things could break.

This is true.

Almost correct, the problem is that to fix bug 1056939, we had to rename the directory where IndexedDB stores DOM Files and since we've been always strict about missing or unexpected files/subdirs, the already "upgraded" directory structure on disk can't be used in older releases :(

I've added troubleshooting docs on this case to MDN[1].
