User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:39.0) Gecko/20100101 Firefox/39.0 Build ID: 20150629110007 Actual results: Options like browser.safebrowsing.malware.enabled are currently providing only the ability to completely disable the related feature or to enable it + activating external communication (for example downloading an up-to-date list). Expected results: Maybe these options could provide an additional value in about:config. false would then map to 0 (feature is disabled) while true would map to 2 (feature is enabled + external communication is enabled). The value 1 would then be used to only enable the feature without any external communication. Additional informations: A use case could be for users who actually don't dislike the related feature but don't trust the connection to a provider like Google. There may also be some minor use cases like complex user setups, etc.

Safe Browsing doesn't work without a regular connection to the external provider: - The lists are downloaded every 30 minutes. They expire after 45 minutes if the update hasn't happened. - The list of malware / phishing site is a list of partial URL hashes (the first 32 bits of a SHA-256 hash). When you have a partial match, you need to download the full hashes for that hash prefix. So I'm not sure exactly what you're suggesting.

I don't know how safebrowsing is working in detail with these hashes. But this issue is not only about the 2 safebrowsing options but about any option that matches such a behavior. For example this would also match the blocklists but I'm thinking the developers are better knowing than me about a full list of the related options.

The add-on blocklist is a completely different mechanism so it would need a separate bug. It doesn't share any code with this. For the Safe Browsing list, I don't understand your suggestion so I don't think we'll be able to do anything about it.
