Is there any software that blocks porn on all browsers that I can install?
You can also use the service openDNS, which limits the name resolution based on the pre-set filters. Compared to the solution proposed for the /etc/hosts file it allows you to not have to constantly update the list. Once you have set your own filters just use openDNS as name server. https://www.opendns.com/home-internet-security/
There are several ways to do this
- Easiest, IMHO, is to use opendns
Opendns has been asked here:
How to configure OpenDns
Once it is configured you configure it here - https://www.opendns.com/welcome/
The advantage is that blacklists are then maintained by opendns.
- The second method is to install and configure a proxy server . You can do this with dansguardian, privoxy, or squid to name a few. You then configure iptables to route all traffic through the proxy or proxy chain.

The disadvantage of this method is that you have to manually update and maintain the blacklist.

You can use iptables, but iptables is inefficient, and you again have to manually maintain a blacklist.
you can use a hosts file. You have to obtain and update the list yourself.

The above link is more for adblock.
The "problem" is that these sites tend to change ip and host names ;)
There's no such thing as "software that blocks porn" -- artifical intelligence is nowhere near up to the job. All you can get is software that blocks websites that someone has blacklisted -- they may be diligently identifying and blocking porn websites, in which case they'll block some (but far from all) porn, or they may be blacklisting their competitors' websites or sites that they object to ideologically.
Various software like Net Nanny, etc. can be used. Alternatives of Net Nanny for linux users may be:
