There's also AdAway for more "traditional" system-wide ad blocking via hosts file or applications like "Tinfoil Hat" which opens the mobile Facebook site in a sandboxed wrapper so you are essentially able to view the site without using their dedicated app or needing to open an incognito tab in Chrome or Firefox before visiting the mobile site. Ads and tracking aside, it's worth it even if just for the lowered system resource usage (my battery life improved by a decent margin even though I still check out Facebook every 1-3 days on my phone).
