Hi Mario, Thomas, I can confirm the behaviour Thomas mentiones.
Yesterday I created a new Firefox profile (I had 'invisible' radio buttons) and got problems with saving after installing the (new 0.3.3) file-backups add-on: saving worked (you could see the flickering download arrow), but the save button stayed red. But one TW did not save at all with the following error in the console: saver-handler: Saving wiki with method autosave through saver tiddlyfox $: /core/modules/utils/logger.js:33:10 save-wiki error: Error columnNumber: 1 fileName: "undefined" lineNumber: 0 message: "filename must not contain back-references (..)" stack: "" __proto__: Object { … } Although my radio buttons reappeared with the new profile, I decided this morning to use my 'old' profile (which had to my best knowlegde an earlier version of the file-backups add-on, 0.2 or so) again to regain normal saving. And yes it did: normal saving with disappearing red save button. Also the TW that did not save with the new profile/add-on, saved again. But after a few hours - without changing a thing - I saw the 'normal' saving has disappeared and the save button stays red again (but saving works, even for the 'problematic' TW). Checking the add-ons revealed version 0.3.3. Can it be that it was updated by Firefox syncing?
