What is Textmarker?
"Textmarker" is a Firefox add-on designed for annotating web pages. Users can highlight and save their selected text permanently, maintain their changes in Textmarker history, and even undo or redo their actions. Additionally, it offers customization of mark styles and shortcuts, synchronization of settings and highlights across devices with a Firefox sync account, and a feature to export these settings and highlights. Users can attach notes to highlights, look up selected words on Wikipedia, and choose the highlighted texts to act as bookmarks. Textmarker does not work in built-in PDF-viewers or Reader Mode.

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 [email protected] 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 :)

Thank you SO much for continuing development! I *just* found this outstanding extension after searching for the *perfect* Webpage annotation add-on, so I really appreciate it! I'd *easily* give it 11 out of 10 stars if there WERE 10 (or 11) stars available! <3

Works just as described.
