I've been having system problems lately, and crashing a lot. Before using VisualEditor, Chromium and Firefox saved my edits when restoring sessions, as long as I am using a persistent login. When using VisualEditor, they are unable to do this. Some type of recovery of in-process edits would be a really nice feature. I think at least for the time being, the lack of this feature is going to prevent me from using it anymore, maybe forever.

There is a recovery system. It is within VisualEditor, not dependent upon your web browser.
