1107076 - Disabling dom.indexedDB breaks sessionrestore in Nightly

Status: RESOLVED DUPLICATE of bug 1079355

(Firefox :: Session Restore, defect)

Description

[msth67]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:37.0) Gecko/20100101 Firefox/37.0
Build ID: 20141202030201

Steps to reproduce:

Disabled dom.indexedDB in Firefox Nightly by toggling dom.indexedDB.enabled to false.


Actual results:

Firefox Nightly fails to restore all windows and tabs from last session (option "Show my windows and tabs from last time" checked in the GUI),instead it hangs indefinitely after starting  to load the first tab.


Expected results:

Firefox should have restored the previous session,given that all sessionstore files are indeed not corrupted, as demonstrated by the fact that simply flipping back the preference restores the previous session- even after repeated failed attempts to restore it with dom.indexedDB.enabled set to false.

Given that this database has by design no limitations to its size,and unlike other storage methods such as cookies or cache has no user-friendly way to inspect and clear its contents, one could want to disable it for privacy/security reasons, and that should not affect Firefox's ability to restore a session.

As it is still happening with release versions, where to date setting dom.indexedDB.enabled to false doesn't impair session restore.

Couldn't reproduce the hang, but the session is not restored.
