According to the website AdGuard uses thr Safe Browsing API for what they call âmalware protectionâ. That is pretty pointless given your browser does that anyway.
Privacy Guides recommends to use ublock origin over adguard.
SB has taken many steps to preserve privacy. If required, a full url is never sent to Google, only a part-hash of the prefix, hidden with noise of other real part-hashes. Firefox takes measures such as stripping out identifying parameters and since SBv4 (FF57+) doesnât even use cookies. (#Turn on browser.safebrowsing.debug to monitor this activity)
This still reveals my ip to Google.
Plus, canât someone as big as Google compare hashes and understand what had been visited (since they crawl websites and have databases with dozens of URLs)?
If you canât trust the proxy. You can use Brave browser. They also run a safe browsering proxy under brave.com domain. Essentially, you donât have to worry about it since you trust the browser already.
OP is on FF-fork so he can use the full uBO instead of uBO lite fyi. uBO also allows for importing blocklists too.
Back to OP:
I run AGH on my router + uBO personally. I used default uBO settings for years and recently started using the more advanced âmediumâ mode which locks things down even further. uBO does have 1-2 malware lists available and you can install additional lists from GitHub and also the ability to block webpage elements.
