Hey there. You can find these settings via the two options: Click the 3-bar menu top right of the browser Click Options Click Advanced

or Paste "about:preferences#advanced" into your URL

Once there you can toggle "warn you when websites try to redirect or reload the page".

As well, to block some sites you can visit these different websites here: https://www.techjunkie.com/block-website-firefox/ https://support.mozilla.org/en-US/kb/block-and-unblock-websites-parental-controls-firef https://addons.mozilla.org/en-US/firefox/addon/leechblock/ https://addons.mozilla.org/en-US/firefox/addon/blocksite/
