Somehow FFox updated itself to 55.0.2 which seems to be the latest version for linux mint.
TW saving stopped working but I imported to classic version 2.8.1 and tiddly fox started working again which I'm very happy about. I was expecting to have more problems. Can I expect to have problems saving again in the near future? -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
