Dear Firefox community. I'm looking for some extension similar to Liner. I tried a lot, and nothing works. I've found, that they had had firefox version some years ago (proof https://twitter.com/getliner/status/857426145775460352). But now - not. I need something similar to it. With cross device selection and sync option.

Maybe they got tired of updating it? https://web.archive.org/web/20210124070946mp_/https://addons.mozilla.org/en-US/firefox/addon/liner-web-pdf-highlighter/reviews/

I don't use any highlighter add-ons myself, but one note for your testing: add-ons are not allowed to inject scripts into Firefox's built-in PDF viewer, so they would be limited to working on web pages.
