This is not very likely. The feature works by downloading a list
of infected sites at a certain interval, then storing this list
in a local file. The file is then consulted during browsing.
So there is no extra query to a single server that has to reply before
a page is shown, like in some competing system.
Hey, Rob, in your first para, you say that a list is downloaded, so in
your second para, you *must be wrong* when you state there is "no extra
query to a single server that has to reply".
Of course, this extra wait time will depend on how often SM has to
download the list of infected sites, daily, weekly, whatever.
The Gecko backend downloads the phishing and malware data in "chunks" at
a low priority. I think it takes up to a week for the complete tables to
be downloaded. After that, any updates are also download in chunks.
So I could still be visiting phishing sites because my database could,
in part, be a week out of date!!
Back in the Triassic when the safe browsing code was still a separate
Google Safe Browsing extension, there was code to do online lookups if
the local copies of the databases didn't have information on a
particular URL, but that functionality was removed a long time ago.
