Yes, you can export your data pretty easily in settings.

Strange, could you please open an issue on GitHub if the problem persisted?

Thanks! :)

Glad you like it! Yes GitHub is the place the community requests new features/enhancements.

In simple terms, link rot is when the contents of a link you saved from the past is longer available.

Firefox sync does save the link url itself, but the actual content is susceptible to being taken down for any reason.

A tool like Linkwarden both saves the link url as well as the content itself, so you’ll have a copy even if the original content is lost. All while taking collaboration into account.
