I have started to suffer this now. I am on a MacMini running MacOS Sierra 10.12.2. I use Firefox 50.1.0 and autosave is enabled; I only used Firefox for TW work. TW version is 5.1.13 and is on a node.js hosted on AWS - I didn't set that up but could get the server setup details is needed.
I have had no browser crashes and I can see no recreatable pattern of circumstances. I have literally watched the text of the tiddler disappear in front of my eyes. Due to the inter-relationships i'm working on i may have 10 tiddlers open at once, maybe 2-5 of those in draft. However, the loss occurs when I have saved and the TW tick has gone from red to grey - soon after saving a tiddler, either that tiddler or another I have open clears. There are no "drafts" of the lost tiddler left. The tags and last saved information remains intact, just the text is cleared. The json export shows it as "". I too have now lost hours of work and considering my options to produce my wiki, so any insights and improvements would welcomed.
