I have the following issue, i gathered what i called "leads" by browsing a lot of sites, but i would like to block the sites that i haved already looked for, something like putting it in a CSV or excel file and just blocked those URL so they wont appear.

Is there any firefox plugin that allow me to set a list of URL a just block them?

The BlockSite plugin is what you are after. It will also disable links to those sites.

Have fun.
