Firefox crash leaves tiddlywiki empty

[konono#9]

Lost all my data in a tiddlywiki - something that doesn't happen all too often nowadays.

I have a large number of tabs open in Firefox, and switch between a number of tabgroups, each with numerous tabs.
I was adding text and images (via external links) to my wiki. Added a map link

<iframe width="100%" height="300px" frameBorder="0" src="http://umap.openstreetmap.fr/en/map/our-new-york-2015_54132?scaleControl=false&miniMap=false&scrollWheelZoom=false&zoomControl=true&allowEdit=false&moreControl=true&datalayersControl=true&onLoadPanel=none&captionBar=false"></iframe><p><a href="http://umap.openstreetmap.fr/en/map/our-new-york-2015_54132">See full screen</a></p>

The link worked fine, except that the map was opened in the same tab instead of in a new tab, which I would have preferred.
At some point Firefox crashed. After restoring, my tiddlywiki was still there, but with 0 bytes!
This shouldn't ever happen.

Involved:
  Firefox 41.0,
  TiddlyFox extension for Firefox 1.0alpha18.1-signed,
  TiddlyWiki 5.1.9

Certainly an uncommon result, but no matter who or what constellation is the culprit: TiddlyWiki should protect itself against losing everything.


Ubuntu Gnome 15.04, Firefox 41.0, TiddlyFox extension for Firefox 1.0alpha18.1-signed

Hope you can improve on an otherwise fantastic tool. Using Tiddlywiki from the very beginnings - thanks to all contributors.

I feel your pain and I don't have any better answer than referring to The First Rule of Using TiddlyWiki. 

Personally, most of my TW use is on TiddlySpot, which has an automatic backup system. Also, a major reason for me to start using Chrome in parallel to FF is that FF crashes too easily.

Hi Konono

I'm sorry to hear what's happened. I'm sure that any of us who have experienced such a catastrophe can only sympathise. Thanks for sharing, too; it does help to keep our minds focused on the importance of improving TiddlyWiki's robustness and reliability.

Best wishes

Jeremy.

Thanks for all the sympathy but that's not what I was looking for. I think fears of data loss can keep people from using tw and that would be too bad for this great tool.
In older 'classic' tw versions you could set an option that made a timestamped copy every time your  tiddlywiki was saved. That led to numerous files, which ultimately led you to shut off this feature.
How about a mechanism that creates a backup or lets say 'shadow' copy of your wiki, and overwrites it every time your wiki is saved. Soemthing like '.mytiddlywiki.html'. Your folder doesn't get flooded with timestamped copies, but you still have a recent backup.
Doesn't matter whose fault it is, if you loose data. Sure, probably Firefoxs crashes are to blame. The wise developer will protect his users from others f-ups.

Thanks and that's it from me. Keep on truckin!

Hi Konono,

I have always hoped to see LessBackupsPlugin ported to TW5,

which would possibly only work with TiddlyFox these days.
Might very well be on the ToDo list for that extension.

Is there ans chance getting the wiki back?
All my Data is gone-... more than a year of work gone....

Thanks
