File Backups 0.9.x
A Firefox extension that saves your TiddlyWiki to disk and keeps a
rotating set of backups next to it. Works with both TiddlyWiki 5
and TiddlyWiki Classic. Single-user, file-based, no cloud. Open
your *.html wiki from file:// and the extension takes care of the
rest.
How it works
Each save writes the wiki to its current location, then drops a rotated
backup into a twBackups/ folder beside it. The rotation is a slightly
modified Tower of Hanoi — by default 9 backup slots, so the most recent
saves stay close at hand and the oldest still go back hundreds of edits.
What’s in 0.9.x
How to use each feature is described in the guides: TiddlyWiki 5 · TiddlyWiki Classic.
Save milestone
An extra, labelled snapshot next to the rotating backups, which the rotation never overwrites. Every milestone is also listed inside the wiki. (TiddlyWiki 5 · TiddlyWiki Classic)
Backup overview
Lists this wiki’s rotating backups and milestones with date, size and an estimated total, each linked to its file, plus a button to open the backup folder. (TiddlyWiki 5 · TiddlyWiki Classic)
Reminders
Three optional reminders, off by default: no milestone for too long, too many backup files, too much disk space. Global defaults in the AddOn options, per-wiki overrides in the wiki. The AddOn only informs — it never deletes your files. (TiddlyWiki 5 · TiddlyWiki Classic)
Folder sync
Compares the backup folder with the AddOn’s records: marks deleted files as missing and adds backups it didn’t know yet, for example after reinstalling the AddOn. (TiddlyWiki 5 · TiddlyWiki Classic)
Opening a backup
When you open a backup or milestone file, the wiki shows which backup it is, with a link back to the main wiki. (TiddlyWiki 5 · TiddlyWiki Classic)
Save As and optional toolbar buttons
TiddlyWiki 5 only: save a copy anywhere in your Downloads folder, and choose which toolbar buttons are shown. (TiddlyWiki 5)
Local file access warning
Since Firefox 153, extensions need permission to access local files. If it’s off, the toolbar icon shows ! and the popup explains how to turn it on. (Home)
Backup-directory validation
If you change the backup folder name in the popup or preferences, the field is checked live and shows an inline error if you enter something the browser would refuse to write to.
Installation
Install from the Firefox Add-ons listing: addons.mozilla.org/en-US/firefox/addon/file-backups.
If you want the latest beta builds, grab the signed .xpi from the
FileBackups GitHub Repository
and drop it into Firefox’s about:addons.
Update notifications
The toolbar icon shows a small ↻ badge when a new release is
available. Click the icon and the popup explains which version, with
[View] linking to the release notes and [Got it] to dismiss.
By default, only stable releases trigger a notification (via Firefox’s built-in extension auto-update). Tick Check for Beta Updates in the extension’s preferences to also be notified when a beta is published — the extension then checks for new betas once every 12 hours, plus each time you open the popup.
The extension makes no telemetry calls and shares no data with third parties. Your wiki content never leaves your machine — the optional beta update check is the only network request, and only fires when you’ve opted in.
