I have the same problem and have started using https://raindrop.io

Hope it serves you well

maybe I'm "that guy", but why does everything have to have thumbnails and icons these days? that's so much space that's wasted instead of harboring more information... we need more geeky, dense, info-rich UIs

I tried Raindrop.io and was impressed enough to get an annual subscription to it.

My main use case was to have a single place for all my bookmarks across Android, iOS, OS X and Linux, and across Firefox and Chrome.

Among all the solutions I evaluated, Raindrop.io had the best UX at the time.
