TiddlyWiki cannot save using Firefox 16.1. Saving changes was not a problem before I upgraded to 16.1 on 10/20/2012.


I just upgraded Firefox on 10/20/2012 on two different Windows OS: Vista (service pack ??) and Windows XP service pack 5.1. I also write TiddlyWiki's. However, when clicking "save changes", I now get this note:

"It's not possible to save changes. Possible reasons include: - your browser doesn't support saving (Firefox, Internet Explorer, Safari and Opera all work if properly configured) - the pathname to your TiddlyWiki file contains illegal characters - the TiddlyWiki HTML file has been moved or renamed"

I didn't have to do anything to configure the earlier version of Firefox. What do I have to do now ... or is there a bug in 16.1? Thanks for your help.
