Stopped working? Some users reported Textmarker stopped working after a Firefox update. Unforntunately neither do we know yet what is causing the issue nor can we reproduce it. For some users it helped to uninstall Textmarker, restart FF, re-install Textmarker - and eventually restart FF again. But other users had to refresh the whole FF profile. If you need to backup your Textmarker data before the uninstall -> here you find how to do that: https://github.com/ufb/Textmarker/issues/84#issuecomment-557044749 Backup your data Please save a backup of your highlights and settings occasionally (you can do so on Textmarker's "Export & Import" page). In the rare case you lost your data due to re-installation just import your backup file Bug reports, problems, suggestions or feature requests via e-mail at undflybir@gmx.de or on https://github.com/ufb/Textmarker/issues Feature requests in reviews (especially ones that lower the average rating) will be ignored. Donations are very welcome - Thank you :) Donate via Ko-Fi Once having Textmarker installed you can open the manual (see screenshot 5) to learn how to use the addon. Attention: Restoration of saved highlights can fail - especially when the corresp. page's text content changes.

Mark text: Select some text (i.e. with mouse), then click key M or 1-5
Save your changes and maintain them in the Textmarker history → [Ctrl] + [Alt] + [S]
Undo/Redo your Textmarker actions using keyboard shortcuts
You can also permanently delete any highlight via context menu.
Customize Mark Styles: Define how exactly the selected text will be highlighted
Choose your shortcuts: You can customize any shortcut.
Syning: In case you have a Firefox sync account and have syncing enabled for addons Textmarker settings and highlights are being synchronized between your devices. If you don't sync your Firefox addons Textmarker will store your data locally.
Export: Settings and saved highlights can be saved to a local file.
Bookmarks: You can make text marks serve as bookmarks (→ on your next visit it will be scrolled to the lowermost bookmark automatically).
Wikipedia Look-Up: Look up selected word on Wikipedia in a seperate tab - [W]
Sticky Notes: Use context menu (right mouse button) for attaching a note to a highlight
