First, why are you using µBO and Nano Adblocker together? They are basically the same thing. Just use one of them and disable the built-in TP because extensions will block first before built-in tracking protection.With ublock origin and nano adblocker the shield icon Enhanced Tracking Protection not show !
Built-in Tacking Protection in Edge Dev, etc. works same way = tracking protection which will block some ads. Depending on which setting is chosen it may cause some site breakage.Firefox's Tracking Protection is not an adbloker, that's not its purpose. It blocks some trackers and as a result blocks some ads too. For complete adlocking experience you should still use an adblocker like uBlock Origin.
Actually, it's required to have the Nano Defender extension installed even after the extra installation steps descried here: uBlock Origin + Nano DefenderFYI - you may scrap Nano Defender extension and add Nano Defender filter list to µBO to simplify.
