While my preferred Feed Reader on Desktop is the excellent FeedBro browser extension, I've been in the market for a decent way to keep feeds synced across multiple devices. I do enjoy using different feed readers on Mobile and Desktop, yes, but the drawback is that I have to manually mark read something on my phone after reading it on my Desktop and visa-versa.

This almost solves my problem. Feeds that I subscribe to are indeed synced across all my devices running Firefox (because they're saved as bookmarks), but there's one fatal flaw that keeps me from dumping FeedBro in favor of this, and I realize it's not something that can be resolved easily due to the limitations of being a browser extension. Simply put, if I subscribe to a feed on one device, it will only update on that device. I can access the feed from my other devices, but it will only refresh the feed on the device that it originated from.

I still give it four star because it DOES sync on technicality, but that's all it has going for it. In general, I find FeedBro to be the more feature rich (and less permission heavy) alternative at the cost of only having my feeds on one local device at a time.

Edit: Browsing the Git-Hub for this extension, I found this: https://github.com/nt1m/livemarks/issues/22 to be a fascinating read. A ongoing journal of past (failed) attempts to make proper Livemark Sync work across multiple devices. At present, the issue is still open, but not updated since 2019. This will be a fascinating development to watch over time, but I doubt there will be a solution soon unless Mozilla were to completely revise how Bookmarks are saved (or better yet, offer their OWN take on integrated RSS feeds in the Firefox Browser again after all these years).
