Saving on TiddlySpot

 23rd April 2021 at 12:40am

Please note: TiddlySpot is in maintenance mode and no longer allows new sites to be created. Instead of TiddlySpot you can now use TiddlyHost, a new service from the creator of TiddlySpot. is a hosting service for TiddlyWiki created in 2006 by Simon Baird and Daniel Baird.

In early 2021 it was superseded by TiddlyHost, a new, secure, modern reimagining of TiddlySpot. Creating new sites on TiddlySpot is no longer supported, (though sites created in 2020 or earlier are still functional).

Security warning for TiddlySpot

Note that your password is sent unencrypted when using TiddlySpot. From the FAQ:

Is Tiddlyspot secure?

No. Tiddlyspot does not use SSL/https, so all TiddlySpot web traffic is vulnerable to packet sniffing. This means your password and site data could be intercepted by a malicious third party. For this reason, please don't keep sensitive information in your TiddlySpot site, and don't use a password that you use for other web sites.

Problems with saving on TiddlySpot

In case you run into this error when uploading a freshly upgraded local TiddlyWiki to TiddlySpot:

Error: NS_ERROR_DOM_BAD_URI: Access to restricted URI denied

The upgrade operation falls foul of a security restriction in Firefox. Until this can be resolved, we suggest using Chrome.

  • Use Chrome to open the local TiddlyWiki document you want to upload to TiddlySpot and follow the steps 1 through 5 described at Upgrading.
  • Once you've checked the TiddlySpot-hosted TiddlyWiki loads properly in Chrome, you should be able to access, edit and save using TiddlyFox again.
  • After you've uploaded your local document once, further editing and saving of the online version hosted on TiddlySpot should work with any modern browser of your choice. (Don't forget to fill in the TiddlySpot password in your TiddlySpot TiddlyWiki control panel for any new browser you want to use for saving changes.)
