How to create a block list?

more options

There is no option in this browser to block a website or to create your own block list. How can I do that, or are you thinking about adding this flexibility in the browser like Microsoft did in his internet explorer 11?

I can't think of any feature like that. Would you like to block yourself from visiting sites just to avoid wasting time there, or is Firefox loading sites that you never requested? There could be a different issue in that case.

Over the years there have been many add-ons for blocking yourself from visiting sites, but I've never tried them myself. Here are some examples. Please read reviews and directions before testing to see whether they suit your needs.
