'any porn sites working without js? Appropriate. 'any libre uncensored 10+ tubes?' Highly inappropriate.
Anyway, most PC stores receive laptops to backup format and reinstall because the user watch porn and got infected by viruses. However that is hardly any worry for a GNU/Linux user, since most malware will target Windows and not other systems.
Apart from that, not using JS and maybe using Tor will be enough. TBB with security settings in like... medium will be enough for 99% of the websites.
