Need to research the influence by removing window.__SS_*

[tetsuharuohzeki]

• 867097 – Remove re-use of __SS_data, and the superfluous __SS_tabStillLoading property
• 867118 – Remove browser.__SS_data and use a WeakMap instead
• 868026 – [Session Restore] Remove window.__SS_dyingCache and replace it with some appropriate use of WeakMap

We need to research the influence by these changes.

They are fixed by the commit 5e34d61.

They are still there. MTH must be updated on these points if they are replaced to weakmaps.

They are obsolete on Firefox 23 and later. (See piroor/treestyletab#508 (comment) )

Outdated.
