Firefox Sync syncs your tabs, bookmarks, passwords, etc. Your read it later list is synced through Pocket (which is owned by Mozilla). They exist on desktop and mobile.
Still using pinboard; one of the best investment I made in my entire life.
The only two things I'm missing in safari to be hones are:
- A no-script extension or similar.
- Sync part of my work is on a no macOS machines I don't have safari there, so no sync. I partially overcome this with bookmaster for bookmarks, but I still missing tabs and read it later list. However, firefox doesn't have this later feature on desktop —and I don't why.
